I have a dryer installed, so why do I get water in my air lines?

The most common cause of water in air lines generates from either a faulty or inadequate air dryer. Direct Air have extensive knowledge and experience with refrigerant, desiccant and membrane dryers and have specialist refrigerant engineers who can diagnose and quickly repair a range of common issues.

How can I get a better quality of air?

The quality of air compressed within your system is directly affected by ambient influences. Contaminants such as water, oil and particles are present in the air around us and get intensified in industrial settings. To improve air quality, you need to consider implementing downstream solutions such as filtration and dryers.

How do I dispose of condensate from my compressed air system legally?

All condensate generated needs to be responsibly disposed as stated in the water industry act of 1991 and the environmental protection regulations of 1991.

Zero loss drains can be installed to remove condensate from your compressed air system and be treated onsite keeping your company compliant with legislation.

What is the quietest air compressor?

Rotary vane and screw compressors are generally available as silenced units.

Typically noise levels range from 40 dBA to 82 dBA dependant upon manufacturer and size.

What is the most energy efficient air compressor?

The most energy efficient air compressor really depends upon the application it is used for. It is widely recommended that when thinking about compressed air energy efficiency you should conduct an energy audit to measure your current usage and identify areas where you could make effective cost saving changes.

What is the difference between a screw, vane and piston compressor?

Rotary Screw Air Compressor

The rotary screw air compressor is probably the most common type of air compressor today. A male and a female screw move towards each other while the volume between them and the housing decreases. The pressure ratio of a screw is dependent on the length and profile of the screw and of the form of the discharge port. The quietest style of air compressor, the maximum pressure achievable from a screw air compressor is 13 bar (188psi). Direct Air & Pipework are distributors of both CompAir and Boge screw air compressors and can offer both oil lubricated or oil free machines.

Vane Air Compressor

A Vane air compressor is driven at very low speed and is favoured for its outstanding reliability. The rotor rotates within a cylindrical stator and is the only continually moving part. The rotor is offset and uses centrifugal force to extend the vanes from their slots forming compression cells. Oil is used to lubricate and seal the cells as they decrease in volume, compressing the air. Direct Air & Pipework supply the popular and reliable Hydrovane air compressor in a range from 1.1kW to 75kW.

Piston Air Compressor

One of the earliest compressor designs, the versatility of the piston compressor allows it to change from compressing both air and gases with very few alterations. Piston compressors are normally quite loud and through multi staging can reach incredibly high pressures for applications such as breathing air.
