Oil-Free Compressed Air
Four architectures, five lines, one promise: no oil in the air stream — from dental clinics to factory clean-air baseload.
Oil-free compressed air is not a feature — it is a requirement. Food and beverage lines, electronics assembly, medical and pharmaceutical packaging, and textile spinning all depend on air that has never contacted lubricating oil — one carryover event can void a batch or trigger a regulator audit.
EMAX delivers oil-free through five lines across four mechanical architectures, each tuned for a different scale, pressure band or purity tier — pick the one that fits your duty cycle and your air-quality requirement.
TAT Oil-Free Piston
1.5 – 4.5 kW. Multi-head parallel platform with cabinet sound enclosure. Dental clinics, surgical air, pharma packaging, lab benches.
Explore TAT-SilentTAT-Star Four-Pressure Oil-Free Piston
4 – 22 kW (5 – 30 HP) · 3 / 8 / 12 / 16 bar. Star-type radial piston, no lubricant in the compression chamber. The 3, 12 and 16 bar tiers are coverage no other EMAX oil-free line publishes.
Explore TAT-StarTSLO Oil-Free Scroll
2.2 – 15 kW (3 – 20 HP). Low-vibration scroll compression, oil-free by design. Lab instruments, sensitive electronics, R&D, medical instrument cleaning.
Explore TSLOTSC-OFW Oil-Free Screw
7.5 – 55 kW. Water replaces oil as the rotor seal medium. Food and beverage process air, textile spinning, multi-station electronics assembly, factory-scale clean-air baseload.
Explore TSC-OFWTSC-OFD Dry Oil-Free Screw
45 – 315 kW (60 – 422 HP) · 7 / 8 / 10 bar. Two-stage dry compression, no oil and no water in the air path. Fixed-speed as standard, PM VSD on request; sized for continuous baseload and the N+1 standby slot.
Explore TSC-OFDOil-free removes the oil. It does not remove the water.
Atmospheric moisture passes straight through a compressor and condenses in the pipework behind it. Of the lines above, only the TSLO 4-in-1 carries a dryer inside its enclosure — both piston lines, the scroll 2-in-1, the water-lubricated screw and the dry two-stage screw leave dew-point control to be specified alongside the machine. ADH refrigerated dryers are matched to the compressor they ship with, up to 165 Nm³/min, and travel in the same container load.

Oil-free architectures span almost an order of magnitude in capex per kW; OPEX (energy, water, filtration replacement) compounds the spread. Run a 5-year projection before you specify.
