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 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 series, the 88111901 is manufactured to Ingersoll Rand global technical standards. It offers low initial resistance, high dust holding capacity, and straightforward installation, making it a core consumable for routine maintenance of SSR M37–M45 compressors.

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 and Installation
Replacement Interval
- Standard conditions: every 4000 hours or 8–12 months, whichever comes first
- High-dust conditions (mining, construction materials, woodworking shops): every 2000–3000 hours
- Replace immediately if visual inspection shows blackened media, heavy dust accumulation, or pressure differential reaches 650 Pa
Installation Steps
- Shut down and isolate: Turn off 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 for media damage, pleat deformation, cracked end caps, or aged gaskets.
- Install the new element: Slide it onto the center stud, ensuring the gasket seats correctly 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 part manufactured to Ingersoll Rand global technical standards and 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 machine serial number for precise matching.
Q3: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows blackened or heavily dust-loaded media; (2) operating differential reaches the alarm value of 550 Pa; or (3) the 4000-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, increases specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear, oil seal degradation, higher oil carryover, and potentially compressor failure.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: No. Different power classes have different element dimensions and flow ratings. Always confirm the correct part number using the machine serial number.
