Midlands UK supplier and authorised distributor of the CompAir D50HRS air compressor range

CompAir D50HRS Compressor

The D50HRS compressor is an oil-free solution from CompAir and has been certified ISO 8573-1 Class Zero (2010) and silicone free, making it better and safer with no risk of oil contamination.

The unique design of the DH range achieves both lower speeds and lower operating temperatures, which results in high efficiency and reduced component wear.

The D50HRS compressor has fewer moving parts than similar machines, meaning there is less to go wrong. The compressor uses a single-stage, direct-driven motor without gears or belts to maximise efficiency and minimise required maintenance.

The water injected design lubricates, cools and seals the compression process, maximising efficiency. With running temperatures of less than 60°C, near isothermal compression is achieved.

Delcos XL control system ensures safe and reliable operation of your compressed air system by continuously monitoring operational parameters: pressure, motor speed, running hours, volume flow. It has a user-friendly touchscreen interface with integrated SD card for in-depth analysis.
