How long are your compressors under warranty?
Subject to maintaining the recommended service and maintenance schedule:
- Most CompAir compressors fall under the Assure warranty for up to 44,000 operating hours or 6 years (whichever is the soonest).
- The Hydrovane ADVANCE warranty is valid for up to 10 years or 48,000 hours on new 4kW-75kW compressors.
- BOGE bestcair offers a 5-year guarantee on all replacement parts.
To discuss the exact warranty details on the air compressor you are interested in, please contact us for more information.
What is a written scheme of examination (WSE)?
Under the Pressure Systems Safety Regulations 2000 (PSSR), all users and owners of pressure systems need to be able to demonstrate that their equipment is safe to use and that they are firmly aware of its safe operating limits.
This is achieved by having a Written Scheme of Examination (WSE) completed by a ‘Competent Person’ with associated thorough examination reports.
Do you provide installation?
All air compressor installation work is carried out by our own fully skilled engineers in compliance with current approved codes of practice and pressure systems regulations.
Our installation team are fully conversant with compressed air, and all cooling and chilled water system requirements.
Our ability to provide a total system solution and turnkey packages while maintaining control over the project from start through to final completion ensures that the air compressor installation system is correct from design to commissioning.
Do you offer finance options on buying new equipment?
Yes, we offer different financing options including leasing and rental packages – available subject to a credit check.

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.
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 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.
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.
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.
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.
