Fixed & Regulated Speed Oil Free
Rotary Screw Compressors
D Series 75-300 kW
CompAir has been designing, manufacturing and supplying oil free screw compressors for more than 90 years.
CompAir’s D range of fixed and regulated speed oil free rotary screw compressors from 75 to 300 kW, generate the highest quality oil free air in accordance with ISO 8573 Class 0, making them the ideal choice for manufacturing processes where air is in direct contact with product or sensitive equipment.
Industries such as; Chemical, Food & Beverage, Pharmaceutical, Electronics and Power Generation, already rely on CompAir for complete oil free peace of mind.
- Generate 100% oil free compressed air
Non contact, non-wearing labyrinth seals prevent bearing lubricant entering the compression chamber.
- Achieve excellent efficiency
The CompAir compression element design sets the industry standard for energy efficiency. Advanced asymmetric rotor profiles and optimized radial and axial porting ensure maximum air output for minimum energy consumption.
- Reduce service costs
Service costs and downtime are kept to a minimum with; a grouped service area, simplified access for cooler cleaning and hinged service access doors all round.
- Save energy (D –RS models)
A number of regulated speed models are available within the D range of oil free rotary screw compressors, using the highest efficiency inverter drives. The regulated speed models precisely match output to demand, allowing the compressors to consume exactly the right amount of energy to do the job, providing excellent energy savings.
- Optimise air cooling (D -A models)
The optimised air cooling arrangement on the air cooled models, ensure that only unheated ambient air passes across the coolers. This maximizes the cooling effect and enables the plant to operate in high ambient temperatures with total reliability.
