How the 1616585187 Oil-Free Screw Air End Works
Oil-Free Compression Without Lubricant in the Chamber
An oil-free screw air end compresses air with two intermeshing rotors while keeping lubricant completely out of the compression chamber. The male and female rotors turn inside a precision-machined housing, trapping air at the inlet and shrinking its volume as the rotors advance. Because no oil enters the chamber, the discharged air carries no oil aerosol — a baseline requirement in food, pharmaceutical, electronics, and breathing-air applications.
The Two-Rotor Compression Cycle
Air enters at the suction port and fills the void between the rotor lobes and the housing wall. As the rotors rotate, this pocket travels along the rotor axis toward the discharge end while its volume falls continuously. Pressure climbs smoothly through the screw profile until the pocket opens to the discharge port. Timing gears hold the rotors in exact relative position so the lobes never touch, which keeps the compression oil-free without a lubricated rotor mesh.
Why Oil-Free Air Matters
Many processes treat compressed air as a direct-contact medium — it mixes with product, instruments, or packaging. Oil traces in that air mean contamination, failed audits, and scrap batches. An oil-free air end removes the oil at the source rather than filtering it out afterward, so the downstream line starts clean. This air end sustains that cleanliness for the full service interval of the O.F.S. G-27 module.

Rotor Profile Precision and Oil-Free Sealing
Asymmetric Rotor Profiles for the G-27 Frame
The rotor pair uses an asymmetric screw profile tuned to the O.F.S. G-27 frame. The lobe geometry sets the internal compression ratio and the sealing line between the two rotors. Small deviations in that profile change the delivered flow and the power draw, so Atlas Copco holds the rotors to tight manufacturing tolerances and balances them for the operating speed of the module.
Timing and Bearing Arrangement
Radial and axial bearings carry the rotor loads from compression pressure and drive torque. The timing gears synchronize the two rotors and maintain the running clearance without metal-to-metal contact. Genuine 1616585187 air ends keep the original bearing specification and gear mesh, which preserves the rotor alignment the module was built to hold.
Sealing the Oil Boundary
In an oil-free screw air end the lubrication lives only in the bearing and timing-gear cavities. Lip seals and labyrinth paths block that oil from reaching the rotors. The 1616585187 carries the factory sealing arran
