Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand intake filter engineered for SSR M37, SSR M37 B, SSR M45, and MM45 series screw air compressors. Its high-efficiency synthetic fiber media blocks dust, dirt, and particulate matter from entering the 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 range, the 88111901 is manufactured to Ingersoll Rand global technical standards. It delivers low initial pressure drop, high dust holding capacity, and straightforward installation — a core consumable for routine maintenance of SSR M37–M45 compressors.

Maintenance & Installation
Replacement Interval
- Standard conditions: every 4,000 hours or 8–12 months, whichever comes first
- High-dust conditions (mining, construction 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: 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 seal remains in the housing groove.
- Clean the housing: Wipe the inner walls and sealing surfaces with a clean cloth. Never reverse-blow and reuse an old element.
- Inspect the new element: Verify part number 88111901, and check for media damage, pleat deformation, cracked end caps, or aged seals.
- Install the new element: Slide it onto the center stud, ensuring the gasket seats evenly top and bottom without skew or twist.
- Refit the cover: Reinstall the cover and tighten the nut 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.
FAQ
Q1: Is the 88111901 a genuine part?
A: The 88111901 is a genuine Ingersoll Rand component 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 M37 B, SSR M45, and MM45 series screw compressors. If you are unsure, provide the compressor serial number and we will confirm the correct part.
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 element is left 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, wearing rotors and bearings, aging oil seals, and increasing oil carryover — potentially leading to airend failure.
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 compressor serial number.
