A 380V three-phase compressed air package for workshops and production lines: 10kW installed power, 320L receiver, 850 L/min at 8 bar, zero oil anywhere in the system.

This industrial oil free air compressor was developed for plants that want one dependable source of compressed air instead of a row of small machines scattered around the workshop. Six 1680W pump sets are managed by a single controller and discharge into a 320-litre receiver, giving 850 litres of usable air per minute at 8 bar — enough headroom for simultaneous demand from lines, jigs and hand tools.
The oil-free construction removes the usual pain points of factory air systems. Since no lubricant ever enters the compression chamber, there is no oil carry-over downstream, no topping-up rounds, no used-oil disposal paperwork, and no coalescing filter elements to replace on schedule. Condensate leaves the drain as plain water.
Quick details
Every design choice below is aimed at one thing: keeping the line supplied during a full production shift.
Splitting 10kW across six modules keeps each unit's duty cycle modest, so temperature stays low during sustained running and the load can follow demand rather than cycling one big block.
Modules come online one after another instead of all at once. Peak inrush current stays manageable on your 380V board, reducing contactor stress and avoiding nuisance tripping.
If a single module is taken out of service, the remaining five continue supplying roughly 83% of rated flow — the shift keeps running and repairs are scheduled, not emergency.
The 320L tank covers short, sharp draws from presses, blow guns and actuators that exceed average consumption, keeping the pressure band narrow where it matters.
Cold-rolled steel laminations slow heat build-up, aluminum housings shed it fast, Class F windings tolerate high internal temperatures, and each motor carries a thermal protector.
Weak grids and voltage dips are common in industrial parks: starting is reliable down to 175V, and the unit is proven across -30℃ to 40℃ ambient conditions.
Sealed, self-lubricating bearings and seamless cylinder sleeves remove routine lubrication entirely — no oil drums to order, store or dispose of.
Five protection layers guard against electrical, thermal, mechanical and over-pressure faults. Fleet data across thousands of installations puts failures below 0.02%.
Typical installations across processing plants, assembly workshops and finishing lines.
Feeds pneumatic clamps, indexing tables and air chucks at several stations at once, with the receiver covering every momentary spike.
Impact wrenches, ratchets, grinders and riveters draw hard and intermittently — 850 L/min sustains several operators working simultaneously.
Clean air without oil aerosol suits cartoners, strappers and filling heads where product contact or contamination rules apply.
Stable 8 bar supply to spray guns and agitation tanks, free of oil contamination that causes fisheyes and reject finishes.
Reliable air for tool changers, spindle seals, part blowing and chip evacuation on machining centres and lathes.
Replaces ageing lubricated piston sets; existing three-phase distribution is usually enough — no service upgrade required.
