Benefits
Two-stage compression
Intercooling between the stages lowers the temperature for efficient work at high pressure.
100% duty cycle
Blocair is built for continuous work, even in tough conditions and at high working pressures.
IE3 direct drive
No belt and no transmission losses; start-stop technology eliminates energy losses during unloading.
Laser cutting
Up to 30 barCutting lasers need plenty of clean air at high pressure. Blocair BL compressors are available for 15, 20 or 30 bar.
Plastics and PET blowing
High pressureAir up to 30 bar for PET blow moulding, plastics forming and pressure testing. Two-stage compression with intercooling handles continuous work.
General industry
Working and control airFor smaller plants and maintenance workshops with occasional or intermittent demand. For continuous, high demand a screw compressor is the better choice.
Metalworking
ProductionWorking and control air for machines, fixtures, pneumatic cylinders and blow-off. Two-stage compressors deliver more air at higher pressure.
