CompAir DH Air Compressors
Oil Free – Contaminant Free
An oil-free DH range compressor from CompAir provides customers with a clean, reliable and cost-efficient air supply that benefits your business and your profitability.
Air purity is critical for many applications where even the tiniest drop of oil can cause product spoilage or damage production equipment. For this reason, the CompAir DH range contains absolutely no oil anywhere in the compressor and has been certified ISO 8573-1 Class Zero (2010) and silicone free, making it better and safer with simply no risk of oil contamination.

Typical Oil-Free Applications
CompAir’s oil-free solutions are proven in thousands of applications across the world, providing high quality, low cost air to manufacturers, processors and operators in a diverse range of industries including:
- Food and beverage
- Engineering & Technology
- CompAir DH – Advanced Compression Technology
The use of absolutely no oil negates the issues of contaminated air. No oil – no risks.
Single-stage, direct-driven compression element maximises efficiency and minimises maintenance
High quality water injection lubricates, cools and seals the compression process, maximising efficiency
No gearbox means no need for associated oil lubrication
Low bearing loads and low speeds mean sealed-for-life bearings can be used, requiring no oil lubrication
Regulated speed technology available to reduce energy costs
Comprehensive control ensures safe and reliable operation and includes remote communication capability
Fully packaged and silenced enclosure reduces noise and simplifies installation
High Quality Features
DH compressors have significantly fewer moving parts than comparable machines, meaning there is less to go wrong, while lower speeds and balanced bearing loads extend the compression element service life for low-cost operation.With exceptionally low running temperatures of less than 60°C near isothermal compression is achieved.This also eliminates the need of an internal aftercooler and associated power consumption reducing pressure drop to the minimum.
High Efficiency Water Purification System
Tried and tested reverse osmosis filtration, provides high quality purified water to lubricate, seal and cool the compression process.Using a permeate pump the water required is reduced to a minimum.
Individual Air Requirements
Regulated speed compressors from CompAir can efficiently and reliably handle the varying air demand. The right regulated speed compressor in the right application delivers significant energy savings and a stable air supply at constant pressure. Maximum efficiency at any level of demand cuts energy costs and saves money.
