Product Overview
88111901 air filter element is a genuine Ingersoll Rand inlet filter element engineered for SSR M37, SSR M37B, SSR M45 and MM45 series screw air compressors. The element uses high-efficiency synthetic fibre media to block dust, dirt and airborne particles from entering the screw airend, protecting rotors, bearings and oil seals from wear and extending compressor service life.
As an original inlet filtration part for the Ingersoll Rand SSR range, 88111901 is built to Ingersoll Rand global technical standards, offering low initial pressure drop, high dust-holding capacity and straightforward installation. It is a core consumable for routine maintenance of SSR M37 to M45 compressors.

Standards
- ISO 5011 — inlet air filter performance testing for engines and compressors (efficiency and dust capacity)

- 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 shops): every 2,000–3,000 hours
- Replace immediately if visual inspection shows darkened media, heavy dust build-up, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and isolate: switch off the main power, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
- Open the filter housing cover: loosen the retaining nut or clips and remove the cover.
- Remove the old element: pull out the old 88111901 element and check whether the centre gasket remains in the housing groove.
- Clean the housing: wipe the inner walls and sealing faces with a clean cloth. Never reverse-blow an old element with compressed air for reuse.
- Inspect the new element: verify part number 88111901; check media for damage, pleats for deformation, end caps for cracks, gasket for ageing.
- Fit the new element: slide it onto the centre stud, ensuring the gasket seats correctly top and bottom without skewing or twisting.
- Refit the cover: replace the cover and tighten the nut or clips evenly to ensure a gap-free seal.
- Start-up check: start the compressor, listen for air leaks at the filter housing and confirm normal operation.
FAQ
Q1: Is 88111901 a genuine original part?
A: 88111901 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and suited to SSR M37/M45 series compressors.
Q2: Which compressors does 88111901 fit?
A: It fits Ingersoll Rand SSR M37, SSR M37B, SSR M45 and MM45 series screw compressors. If you are unsure, provide the compressor serial number and we will match it precisely.
Q3: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows darkened media or heavy dust; (2) differential pressure reaches the 550 Pa alarm value; or (3) the 4,000-hour or 8–12 month interval is reached.
Q4: What happens if the air filter element is too dirty?
A: A clogged element restricts inlet air, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear and oil seal ageing, which can increase oil carryover and even lead to airend failure.
Q5: Can 88111901 be interchanged with other SSR air filter elements?
A: Elements for different SSR power ranges differ in dimensions and rated flow and are not freely interchangeable. Always confirm the correct part number using the compressor serial number.
