In our daily sales work, we have noticed that some air compressor users don't really understand how to choose the right compressor specially if they are only responsible for the purchase and finance departments. So, we decided to start a course to help all friends, so if you are a DENAIR client or not, you are all welcome to ask us anytime if you have any question about Air Compressors.
Today, we will start with the basics; Capacity and pressure
Pressure and capacity are the two main specifications to look for when buying an air compressor;
- Pressure is expressed in bar or PSI (pounds per square inch).
- Capacity is expressed in CFM (cubic feet per minute), liters per second, or cubic meters per hour/minute.
Remember: pressure is 'how strong', capacity is 'how much.
- What's the difference between a very small and a very large compressor? It's not the pressure, it's the capacity.
What pressure do I need?
Most compressed air equipment is designed to operate at around 7 to 10 bar, For this reason, most people only need a compressor with a maximum pressure of 10 bar, For some applications, higher pressure is needed, like 15 or 30 bar. Sometimes even up to 200 - 300 bar or more (scuba diving and paintball for example).
How much pressure do YOU need?
Look at the tools or machines you use, it should state the required minimum pressure but be sure to check the specs or ask the manufacturer.
What size/capacity (CFM/m3*min) do I need?
Capacity is the amount of air that the compressor can pump out. It is expressed in CFM (cubic feet per minute).
How much capacity do you need?
Add up the requirements for all the air tools and machines that you have.
This is the maximum capacity that your equipment requires together.

why choose us
The longer service life of the master machine
The rotor uses an asymmetrical line running at a low speed with the support of the ball bearings and roller bearings as a result. The damage and the cost are lowered and the service life is extended. Some force is counteracted by the axial force generated by the bevel gear. So the load on the bearings of the master machine is lowered.
Permanent alignment of the electromotor and the master machine
Different from the strap compressor, the SRC series compressor can integrate the electromotor with flange, shaft coupling box-gear box. and the master machine into one in such way the master machine and the electrometer are aligned forever in the transpiration. The SRC series compressors equipped with an effective and fully sealed air-cooling electromotor.
