AFU 13/25

1. AO filter: removes dirt particles (down to 1×10⁻⁶ m)

2. AA filter: removes oil mist, water aerosol, finer particles (down to 0.01×10⁻⁶ m)

3. AC filter (activated carbon): removes oil vapors and odors, reducing residual oil content to very low levels (~0.003 mg/m³)

Maximum inlet pressure is 10 bar (if higher, a regulator is needed)

These filter units do not remove carbon monoxide (CO), carbon dioxide (CO₂), or other toxic gases; they only remove particulates, oil, water, and odors.

Filter element replacement schedule:

• First and second stage: after 6,000 hours or every 12 months, whichever is sooner

• Third stage (carbon filter): max 1,000 hours or 2 months (whichever is sooner) for effective odor removal
