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 and particulate matter from entering the airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.
As an OEM intake filtration component for the Ingersoll Rand SSR range, the 88111901 is built to Ingersoll Rand global technical standards. It combines low initial pressure drop, high dust holding capacity and straightforward installation, making it a core consumable for routine maintenance of SSR M37–M45 compressors.

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): 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 gasket 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, 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, ensuring the gasket seats evenly top and bottom without skewing or twisting.
- 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 Ingersoll Rand part?
A: Yes. The 88111901 is a genuine Ingersoll Rand replacement part manufactured to Ingersoll Rand global technical standards for SSR M37/M45 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 verify the correct part for your machine.
Q3: How do I know when to replace the air filter element?
A: Replace it 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 is not replaced in time?
A: A clogged element restricts intake, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear and seal aging, which can increase oil carryover and even lead to airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filters?
A: SSR models of different power ratings use elements with different dimensions and flow capacities, so they are not freely interchangeable. Always confirm the correct part number by serial number.
