Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand intake filter designed for SSR M37, SSR M37 B, SSR M45 and MM45 series screw air compressors. Its high-efficiency synthetic fiber media blocks dust and airborne particles from entering the airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.
Produced to Ingersoll Rand global technical standards, the 88111901 combines low initial pressure drop, high dust-holding capacity and straightforward installation. It is a core consumable for routine maintenance across the SSR M37–M45 range.

7. Standards
- ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors: performance testing

- GB/T 14295 — Air filters
- GB/T 6165 — Test methods for air filter performance (efficiency and resistance)
Maintenance & 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 loading, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and lock out: switch off the main power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
- Open the filter housing: loosen the retaining nut 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 surface with a clean cloth. Never reverse-blow an old element with compressed air and reuse it.
- Inspect the new element: verify part number 88111901, check media for damage, pleats for deformation, end caps for cracks, and gasket for aging.
- Install the new element: slide it onto the center stud and ensure the gasket seats correctly top and bottom without skewing or twisting.
- Refit the cover: reinstall the cover and tighten the nut or clips evenly to ensure a gap-free seal.
- Start-up check: start the compressor and check for air leakage around the filter housing and normal operation.
FAQ
Q1: Is the 88111901 a genuine Ingersoll Rand part?
A: Yes, the 88111901 is a genuine Ingersoll Rand part produced to Ingersoll Rand global technical standards 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, provide the machine serial number and we will confirm exact fitment.
Q3: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows blackened media or heavy dust loading; (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 air filter 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, seal aging, higher oil carryover, and potentially airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filters?
A: SSR models of different power ratings use different filter dimensions and flow capacities and are not freely interchangeable. Always confirm the correct part number using the machine serial number.
