A screw compressor is today the most widely used type of compressor in industry – and for good reason. It delivers a stable and continuous compressed air and gas supply, compressed air supply, requires limited maintenance and is also both quiet and energy-efficient in operation.
A screw compressor compresses air using two counter-rotating screws (rotors). The air is drawn into the compressor, and as the screws rotate, the air volume is gradually reduced. This increases the pressure until the compressed air is delivered into the compressed air system.
This compression method provides a smooth and stable air flow without large pressure fluctuations. This makes screw compressors particularly suitable for operating situations where constant compressed air and high uptime are required.
If you have a continuous or regular compressed air demand, a screw compressor is often the best choice. It is designed for many operating hours and provides a stable compressed air supply that suits professional environments well.
Typical advantages include:
Screw compressors are typically available as either oil-injected or oil-free solutions, and the choice mainly depends on the requirements for compressed air quality.
Oil-injected screw compressors are a very common solution in industry and often provide a strong combination of efficient operation and long service life. They are used in many types of production and technical installations.
Oil-free screw compressors are typically chosen in applications where particularly high requirements for air quality are needed, for example in selected process environments and production where clean air is critical.
If you are unsure what best suits your operation, we are happy to help with clarification and correct sizing.
If your compressed air demand varies throughout the day, a variable speed screw compressor (variable speed drive) can be an ideal choice. Here, the compressor output is continuously adjusted to the current demand, which typically results in lower energy consumption during fluctuating loads.
This is particularly relevant in companies where compressed air is not used constantly in the same amount – for example with changing production, varying staffing or periods with low load pressure.
The right solution depends not only on the size of the compressor, but also on the operating pattern and requirements. When we advise on the selection of a screw compressor, we typically base it on:
The goal is to ensure a solution that works both technically and provides good operating economy.
At Dansk Trykluft Industri, we offer both new and used screw compressors. A used solution can be attractive if you want a professional compressor at a lower investment – without compromising operation and functionality.
Whether you choose new or used, we are happy to advise on model selection, capacity and setup so the solution matches your needs.
A screw compressor is often the best choice when you use compressed air regularly or continuously. It provides high operational reliability, lower noise levels and a more stable air flow than many alternative compressor types. Therefore, it is often chosen in companies where compressed air is an important part of operations.
An oil-injected screw compressor uses oil in the compression process, which helps with lubrication, sealing and cooling. It is a very common solution in industry where efficient operation and long service life are desired. An oil-free screw compressor is typically used in environments where particularly high requirements for air purity are needed and where compressed air without oil content is required.
A variable speed screw compressor regulates the motor speed so the compressor adjusts its output to the current compressed air demand. This can provide more energy-efficient operation in companies where air demand varies throughout the day. In practice, it can reduce energy consumption and provide more stable operation without unnecessary “idle running”.
The correct sizing depends, among other things, on capacity (air consumption), operating pressure and operating profile. A compressor that is too small can cause unstable pressure and strain on the system, while a compressor that is too large can lead to unnecessary costs. We are happy to help assess the requirements and choose a solution that fits both operations and finances.

En oliefri kompressor er en maskine, der producerer trykluft uden brug af olie i kompressionskammeret. Dette betyder, at den trykluft der produceres, er fuldstændig fri for olierester og forurenende stoffer, hvilket gør den ideel til applikationer, hvor renhed er afgørende, såsom inden for medicinalindustrien, fødevareproduktion og elektronik.
Oil-free compressors operate by using specially designed piston or screw mechanisms that do not require oil for lubrication in the compression process. Instead, they use high-performance materials and advanced cooling systems to minimize wear and ensure efficiency. This results in reliable operation and clean compressed air that meets strict standards.
Valget af en oliefri kompressor afhænger af flere faktorer, herunder dit specifikke behov for luftkvalitet, trykniveau, flowhastighed og budget. Det er vigtigt, at vælge en kompressor der passer til dit anvendelsesområde, og som kan levere den nødvendige kapacitet. Overvej også energiforbrug og vedligeholdelseskrav.
We offer a wide range of oil-free compressors suitable for different applications, such as:
Oliefri kompressorer anvendes i en bred vifte af industrier, hvor høj luftkvalitet er afgørende.

En professionel stempelkompressor, også kendt som en stempelluftkompressor, er en maskine der anvendes til at komprimere luft eller gas ved hjælp af en stempelmotor. I denne type kompressor bevæger en stempelstang sig frem og tilbage inde i en cylinder for at reducere volumen og øge trykket af den indfangede luft eller gas. Stempelkompressorer er blandt de ældste og mest anvendte kompressorer i industrien, og de fås i både enkelt- og flerstadige modeller, afhængigt af de ønskede trykniveauer.
A piston compressor operates in a simple but effective way. When the piston rod moves downward in the cylinder, a vacuum is created that draws air in through an intake valve. When the piston moves upward again, the intake valve closes and the air is compressed as it is forced out through a discharge valve. This creates pressurized air that can be used for various purposes. This cycle repeats continuously during operation, making it possible to deliver a steady flow of compressed air.
When investing in a piston compressor for industrial or professional use, it is crucial to choose a model that matches your operational requirements and ensures stable, efficient production. Here are the key parameters you should evaluate:
Start med at definere det konkrete anvendelsesområde. Skal kompressoren bruges til intermitterende opgaver som drift af enkelte pneumatiske værktøjer, eller til kontinuerlig forsyning af produktionslinjer? En kompressors duty cycle indicates how much of the time it can run without being overloaded. For heavy, continuous operation, you should choose a model with a 100% duty cycle.
It is not enough to look at motor power. The compressor’s actual performance is measured in free air delivery (FAD)which indicates the amount of usable compressed air delivered at a given pressure.
Always size the compressor so that the FAD exceeds your maximum consumption, including peak loads, to avoid pressure drops and inefficient operation.
Most industrial applications require an operating pressure of 8–10 bar, but certain processes, for example in the food or metal industry, may require higher pressure. Make sure the compressor has sufficient pressure capacity to handle both current and future needs, and that the air quality meets the requirements of your production – for example through air quality analysis.
An efficient cooling solution is crucial to avoid overheating, especially under high load. Professional piston compressors are often equipped with forced air cooling or oil cooling, which extends service life and reduces maintenance costs.
Choose a model with robust components, easy access to service points and quality materials that ensure high operational reliability.
Piston compressors are used in many different industries and applications, including:
When comparing piston compressors with screw compressors, there are several differences that can influence the choice. Piston compressors are known for their simplicity, reliability and economical price, which makes them ideal for smaller and medium-sized tasks. However, they require regular maintenance and can be noisier than screw compressors.
Screw compressors, on the other hand, are more complex but offer higher efficiency, lower noise levels and can often run continuously for longer periods without overheating. They are better suited for larger industrial applications where a constant compressed air supply is required.
A screw compressor has several advantages that make it a good choice for larger industrial purposes:
By taking application requirements and budget into account, both piston and screw compressors can offer effective solutions for different compressed air needs. At Dansk Trykluft Industri, we offer compressors designed for intensive daily use with a focus on minimal downtime and low total cost of ownership over the machine’s lifetime. It is also possible to rent a compressor or rent compressed air equipment.
A high-pressure compressor is used when standard compressor solutions are not sufficient and there is a need for higher working pressure, high operational reliability, and a stable supply. This may be in production, in a workshop, or as part of a process where compressed air plays a critical role.
Hos DTI A/S leverer vi højtrykskompressorer til erhverv, hvor kravene til kapacitet, oppetid og kvalitet er høje – og hvor løsningen skal passe præcist til driften.
High-pressure compressors are used in many industrial setups where pressure, volume, and operating time must be documented and delivered consistently. They are used, among other things, for:
If you have a specialized application, we are happy to advise on the right solution and the best operational reliability in practice.
The choice of a high-pressure compressor should always be based on the actual operational needs – not just a pressure rating on paper. The most important parameters are:
1) Pressure and operating point
What working pressure must the system deliver – and does it need to be continuous or only required periodically? We help with sizing, so you do not end up with overcapacity or undercapacity.
2) Capacity and consumption (m³/h or l/min)
How much compressed air do you need per hour, and how often does the compressor need to deliver it? A correct match results in lower energy consumption and fewer operational stoppages.
3) Operating time and load profile
Should the compressor run for a few hours per week or across multiple shifts? The load profile has a significant impact on both the technology, cooling, and expected service life.
4) Environment and installation
Location, temperature, ventilation, and noise requirements all play a role – especially when operating in production environments or technical facilities. Here, the right setup can make a significant difference for both performance and maintenance.
A high-pressure compressor is often an investment that must be able to deliver consistently over many years. Therefore, many companies choose high-pressure solutions when the demands for operation and process are high.
You get a solution that can operate consistently at high pressures without performance declining as the load increases.
When the system is properly sized, a high-pressure compressor can contribute to fewer operational disruptions and more predictable operation.
With the right operating point and the correct capacity, you avoid unnecessary energy waste and achieve better utilization of your compressed air system.
In many industrial environments, compressed air is not “just air.” Depending on the application, it may be relevant to consider:
We are happy to advise on the complete solution, ensuring that both the compressor and downstream treatment match the operational requirements and process.
High-pressure compressors are often used in industry, where compressed air is a critical part of operations. This may include the automotive and transport sector, laboratories and test environments, the pharmaceutical and process industries, as well as energy and manufacturing companies with high demands for uptime and pressure stability.
The right choice depends on several factors: required working pressure, air volume/capacity, operating time and load profile, as well as environmental and installation conditions. At Dansk Trykluft Industri, we help with sizing and selecting the right solution, ensuring the compressor matches your needs in practice – not just on paper.
A standard compressor is typically used for general compressed air tasks in, for example, workshops and production, while a high-pressure compressor is designed for higher pressures and more demanding operating conditions. High-pressure compressors are often chosen when stable pressure, operational reliability, and a robust solution are essential.
The capacity depends on your consumption, the number of consumption points, and whether the compressed air is used continuously or in intervals. A correctly sized solution provides better operation, lower energy consumption, and a reduced risk of pressure drops – therefore, we always recommend basing it on your actual load profile.
Yes, in many B2B environments, air quality is important – especially in process applications, testing, laboratories, and production, where stable operation and clean compressed air can be critical. Filtration, drying, and condensate management should be assessed as part of the overall solution to ensure optimal operation and minimize downtime.
Driftstid og belastningsprofil har stor betydning for, hvilken løsning der giver mest mening økonomisk og teknisk. Hvis kompressoren skal køre i lange driftscyklusser eller flere skift, stiller det højere krav til både dimensionering, køling og robusthed – og her kan den rigtige løsning give markant bedre stabilitet og levetid.
When compressed air is a critical part of operations onboard or in offshore installations, there is no room for uncertainty. Marine compressors must be able to deliver stable performance in demanding environments with high temperatures, vibrations, and varying loads. Therefore, ALMiG marine compressors are developed with a focus on robustness, operational reliability, and long service life.
The compressors are designed for stable operation – even at ambient temperatures up to 50 °C – and are suitable for a wide range of maritime applications.
In maritime installations, compressed air is typically used for two purposes: control air and working/process air. While control air often requires stability and operational reliability for control and automation, working/process air can be more demanding in terms of load and may vary in consumption.
ALMiG marine compressors can be configured to match the specific application – whether the focus is on stable control, high supply reliability, or operation under varying consumption patterns.
Compact single-stage screw compressor – easy to integrate onboard
ALMiG marine compressors are built as single-stage, oil-injected, and air-cooled screw compressors, making them both efficient and operationally stable in daily use. At the same time, the solution is developed with a compact design, allowing for space-saving installation – for example, close to walls or in corners, where space is often limited onboard.
This provides flexibility in engine rooms and technical spaces, where considerations must include operation, service access, and space optimization
ALMiG marine compressors cover a relevant performance range for many marine applications. The solution is typically delivered in capacities from 1.50–5.17 m³/min at 8 bar(g), and models can also be supplied for 10 or 12 bar(g) depending on the installation and requirements.

In maritime environments, equipment is exposed to conditions that place particularly high demands on construction. Salt, humidity, temperature variations, and vibration can affect both components and operational reliability.
With an ALMiG marine compressor, you get a solution that is developed for stable operation under demanding conditions. This contributes to fewer unexpected stoppages and more predictable operation over time.
In many installations, the compressor is a significant part of the energy consumption. Therefore, the choice of a marine compressor should not only be about performance here and now – but also about operating economy over time.
ALMiG marine compressors are developed with a focus on efficient operation and high uptime. This provides a strong foundation for reducing energy waste, minimizing operational losses, and achieving better overall economy – especially in operating situations where compressed air is a regular part of daily operations.
Marine compressors must be easy to monitor, control, and optimize – especially when operational reliability and energy optimization are in focus. ALMiG is supplied with modern control systems and touch operation, making it easy to work with operating data and settings.
In addition, the solution can be integrated into overall control systems, enabling better monitoring, planned maintenance, and a more data-driven approach to operation.
