Benefits
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.
Built to suit
Power pack for OEMs, on a base (plug & play), on a 90, 270 or 500 l receiver, or Full Feature with dryer and filters.
Food and beverage
No oil contaminationAir for packaging machines, beverage filling and pneumatic valves where oil must never touch the product. Oil-free compressors remove that risk.
Laboratories
Analysis and testingQuiet, oil-free air for analysers, test rigs, pneumatic valves and autoclaves. A small compressor can stand right in the room where you work.
Medical and healthcare
Clean, dry airOil-free air for medical devices, sterilisation and hospital equipment. A dryer and filters keep the air dry and clean.
Control and automation
Control airConstant pressure for pneumatic valves, cylinders, automatic doors and control systems. Quiet compressors with filter and regulator can sit next to the machine.
