Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand intake filter element built for SSR M37, SSR M37 B, SSR M45 and MM45 series screw air compressors. Its high-efficiency synthetic fiber media blocks dust, dirt and airborne particulate before it reaches the airend, protecting rotors, bearings and oil seals from wear and extending compressor service life.
Produced to Ingersoll Rand's global technical standard, the 88111901 combines low initial pressure drop, high dust-holding capacity and straightforward installation — a core consumable for routine maintenance of SSR M37 to M45 machines.

7. Applicable Standards
- ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors: performance testing (efficiency and dust capacity)
- ISO 16890 / EN 779 — Classification of general ventilation air filters
- GB/T 14295 — Air filters
- GB/T 6165 — Test methods for air filter performance (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 blackened media, heavy dust accumulation, or differential pressure reaching 650 Pa
Installation Steps
- Shut down and isolate: switch off the compressor main power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
- Open the filter housing cover: release the retaining nuts or clips and remove the cover.
- Remove the old element: pull out the old 88111901 element and check whether the center gasket remains in the housing groove.
- Clean the housing: wipe the inner walls and sealing faces with a clean cloth to remove dust and debris. Never reverse-blow an old element with compressed air and reuse it.
- Inspect the new element: verify part number 88111901, and check media for damage, pleats for deformation, end caps for cracks, and gasket for aging.
- Install the new element: slide it onto the center mounting stud, ensuring the gasket seats correctly top and bottom without skewing or twisting.
- Refit the cover: replace the cover and tighten nuts or clips evenly to ensure a gap-free seal.
- Start-up check: start the compressor, listen for air leakage at the filter housing, and confirm normal operation.
FAQ
Q1: Is the 88111901 a genuine Ingersoll Rand part?
A: Yes. The 88111901 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand's global technical standard and designed for SSR M37/M45 series compressors.
Q2: Which compressors does the 88111901 fit?
A: It fits Ingersoll Rand SSR M37, SSR M37 B, SSR M45 and MM45 series screw compressors. If you are unsure about your model, provide the machine 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 blackened media or heavy dust; (2) operating 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 element is too dirty?
A: A clogged element restricts intake 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 aging, which raises oil carryover and can ultimately scrap the airend.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: Elements differ in size and rated flow across SSR power ranges and are not freely interchangeable. Always confirm the correct part number using the machine serial number.
