The Atlas Copco O.F.S. M‑26 air‑end, part number 1616590463, is an original dry‑type oil‑free screw compression element designed for Atlas Copco oil‑free compressed‑air systems. As the core heart of oil‑free screw compressors, this air‑end delivers 100% oil‑free compressed air without oil injection inside the compression chamber, catering to industrial production requiring ultra‑clean process air.
When production cannot tolerate even trace oil aerosols in compressed air, the air end becomes the most critical single component in your entire system. The Atlas Copco O.F.S. M-26 (1616590463) is purpose-built for this high-stakes requirement. Unlike flooded screw elements that rely on oil for sealing and cooling, this dry screw air end achieves compression without injecting oil into the rotor chamber. The outcome is certified oil-free compressed air for sensitive manufacturing workflows.
the Atlas Copco O.F.S. M-26 air end, part number 1616590463, acts as the core compression element for Atlas Copco oil-free rotary screw compressors. We source this unit directly from Atlas Copco (Shanghai) Trading Co., Ltd., and we supply only brand-new, genuine stock. This dry screw air end delivers Class 0 oil-free compressed air for industries that cannot accept even trace oil contamination in process air.
Working Principle
Two distinct screw air end designs serve Atlas Copco compressor fleets: oil-injected air ends and dry oil-free air ends such as the O.F.S. M-26. An oil-injected screw air end uses counter-rotating male and female rotors. The compressor injects cooling lubricant directly into the compression chamber. This oil seals internal clearances between rotors, absorbs compression heat and reduces rotor friction. The compressed air and oil mixture flows out of the chamber, and downstream separators remove most oil from the air stream. This design delivers stable flow at lower upfront cost, but trace oil carryover always remains a risk for sensitive production lines.
The O.F.S. M-26 air end follows a different compression principle. Synchronisation gears keep the coated rotors separated during rotation, so rotors never touch each other. No oil enters the compression cavity at any stage. Precision non-contact seals isolate bearing lubrication from the air flow path. Air enters the suction port, fills the rotor grooves, and compresses as the rotor volume shrinks along the element. The finished compressed air exits completely free of compressor oil. Separate cooling circuits manage the high heat generated during dry compression to protect rotor coatings and maintain stable clearances.

Maintenance Schedule
Your maintenance team must follow structured inspection cycles for dry screw air ends, because dry compression creates tighter tolerance limits than oil-injected units. Carry out vibration, temperature and seal condition checks every 2,000 operating hours. Inspect rotor coatings and internal clearances during major service at 8,000 operating hours. Plan full air end replacement when you see sustained flow loss, rising discharge temperature, abnormal rubbing noise, failed air purity tests or seal degradation. Many facilities schedule proactive replacement during planned shutdowns between 20,000 and 40,000 running hours. Actual service life depends on ambient dust levels, cooling system health and load cycles.
You must replace associated consumables including shaft seal assemblies, gaskets and inlet filter elements whenever you swap this air end. Keep the cooling circuit fully cleaned and serviced to avoid thermal damage to rotor surfaces.

Installation Guidance
Only certified Atlas Copco compressor technicians complete air end replacement work.
Isolate the compressor, release all internal air pressure and lock out electrical power before you start disassembly.
Remove guard panels, disconnect cooling lines, air flanges and drive couplings from the worn air end.
Lift the old air end carefully using rated lifting gear and clear the mounting base. Clean all contact surfaces and inspect the base for damage.
Unpack the new 1616590463 O.F.S. M-26 and inspect the unit for transit damage before fitting.
Position the new air end onto the mounting frame, then align the drive coupling. Use dial indicators to check alignment and correct offset to manufacturer tolerances. Misalignment causes rotor contact and rapid failure.
Torque all mounting bolts and flange fasteners to values listed in the service manual. Reconnect cooling pipes, air connections and sensor wiring.
Fit new gaskets and seal kits. Double-check every connection to eliminate leaks.
Complete a no-load test run first. Monitor vibration, discharge temperature and noise for 30 minutes. Gradually ramp the compressor to normal working pressure.
Log all readings and run an air purity test before returning the compressor to production duty.
