Product Overview
88111901 air filter element is a genuine Ingersoll Rand intake filter designed for SSR M37, SSR M37B, SSR M45, and MM45 series screw air compressors. Its high-efficiency synthetic fiber media blocks dust, dirt, and particulate matter from entering the screw airend, protecting rotors, bearings, and oil seals from wear and extending compressor service life.
As an original intake filtration component for the Ingersoll Rand SSR series, the 88111901 is manufactured to Ingersoll Rand global technical standards. It offers low initial resistance, high dust holding capacity, and straightforward installation — a core consumable for routine maintenance of SSR M37–M45 compressors.

Maintenance & Installation
Replacement Schedule
- 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 the media is visibly blackened, heavily loaded, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and isolate power: Turn off the main compressor power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
- Open the air filter housing: Loosen the retaining nut or clips and remove the cover.
- Remove the old element: Pull out the used 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 a used element with compressed air for reuse.
- Inspect the new element: Verify part number 88111901; check media for damage, pleat deformation, cracked end caps, or aged gaskets.
- Install the new element: Slide it onto the center stud, ensuring the gasket seats evenly top and bottom without skewing or twisting.
- Refit the cover: Reinstall the cover and tighten nuts or clips evenly for a gap-free seal.
- Start-up check: Start the compressor, listen for air leaks at the filter housing, and confirm normal operation.
Frequently Asked Questions
Q1: Is the 88111901 a genuine original part?
A: Yes, the 88111901 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards, suitable for SSR M37/M45 series compressors.
Q2: Which compressors does the 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) the media is visibly blackened or heavily loaded; (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 element is too dirty?
A: A clogged element restricts intake, reduces discharge volume, raises specific power and energy consumption, and in severe cases allows dust into the airend, causing rotor and bearing wear, oil seal aging, higher oil carryover, and even airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: SSR models of different power ranges use different element sizes and flow capacities and are not freely interchangeable. Always confirm the correct part number by serial number.
