Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand inlet filter engineered for SSR M37, SSR M37 B, SSR M45 and MM45 series screw air compressors. Its high-efficiency synthetic fibre media blocks dust, dirt and airborne particles before they reach the airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.
As an original inlet filtration component for the SSR range, the 88111901 is built to Ingersoll Rand global technical standards. Low initial pressure drop, high dust-holding capacity and straightforward installation make it a core consumable for routine maintenance of 37–45 kW SSR machines.

Standards Referenced
- ISO 5011 — inlet air filter performance testing (efficiency and dust capacity)
- ISO 16890 / EN 779 — classification of general ventilation air filters
- GB/T 14295 — air filters
- GB/T 6165 — air filter performance test methods (efficiency and resistance)
Maintenance and Installation
Replacement interval
- Standard conditions: every 4,000 hours or 8–12 months, whichever comes first
- High-dust conditions (mining, building materials, woodworking): every 2,000–3,000 hours
- Replace immediately if media is blackened or heavily loaded, or if differential pressure reaches 650 Pa
Installation steps
- Shut down and isolate — switch off the main power, apply lock-out/tag-out (LOTO) and confirm the machine has fully stopped.
- Open the filter housing — release the retaining nut or clips and remove the cover.
- Remove the old element — pull out the used 88111901 and check whether the centre gasket remains in the housing groove.
- Clean the housing — wipe the inner wall and sealing face with a clean cloth. Never reverse-blow and reuse an old element.
- Inspect the new element — verify part number 88111901, check media for damage, pleat deformation, cracked end caps or aged gaskets.
- Fit the new element — slide it onto the centre stud, ensuring the gasket seats evenly top and bottom without twisting.
- Refit the cover — tighten the nut or clips evenly for a gap-free seal.
- Start-up check — run the compressor and listen for air leaks around the filter housing.
FAQ
Q1: Is 88111901 a genuine Ingersoll Rand part?
A: Yes — 88111901 is an original Ingersoll Rand component produced to Ingersoll Rand global technical standards for SSR M37/M45 series compressors.
Q2: Which compressors does 88111901 fit?
A: It fits Ingersoll Rand SSR M37, SSR M37 B, SSR M45 and MM45 series screw compressors. If you are unsure, provide the machine serial number and we will confirm exact fitment.
Q3: How do I know when to replace the air filter?
A: Replace when media is visibly blackened or heavily loaded, when differential pressure reaches the 550 Pa alarm value, or when the 4,000-hour / 8–12 month interval is reached.
Q4: What happens if the filter is left too dirty?
A: A clogged element restricts inlet air, reducing displacement and raising specific power and energy cost. In severe cases dust enters the airend, wearing rotors and bearings, ageing seals and raising oil carry-over.
Q5: Are SSR air filters interchangeable across models?
A: No. Filter dimensions and rated flow differ by power class. Always confirm the correct part number against the machine serial number.
