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, dirt and particulate matter from entering the airend, protecting rotors, bearings and shaft 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 combines low initial restriction, high dust-holding capacity and straightforward installation — a core consumable for routine maintenance of SSR M37 to M45 compressors.

7. Applicable Standards
- ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing (efficiency and dust capacity)

- GB/T 14295: Air filters
- GB/T 6165: Test methods for air filter performance (efficiency and resistance)
Standard 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 shops): every 2,000–3,000 hours
- Replace immediately if visual inspection shows dark or heavily loaded media, or if differential pressure reaches 650 Pa
Installation Steps
- Shut down and isolate: Switch off main power, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
- Open the filter housing cover: 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 face with a clean cloth to remove dust and debris. Never reverse-blow an old 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 the new element onto the center stud, ensuring the gasket seats correctly on both sides 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, listen for air leaks at the filter housing, and confirm normal operation.
FAQ
Q1: Is the 88111901 a genuine original part?
A: The 88111901 is a genuine Ingersoll Rand original component, manufactured to Ingersoll Rand global technical standards 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 about your model, provide the machine serial number and we will match it precisely.
Q3: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows dark or heavily loaded media; (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 causes insufficient intake, reduced discharge volume, higher specific power and increased energy consumption. In severe cases, dust enters the airend, wearing rotors and bearings and aging shaft seals, which raises oil carryover and can lead to airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: Air filter elements differ in size and flow capacity across SSR power ranges and are not freely interchangeable. Always confirm the correct part number using the machine serial number.
