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 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 SSR range, the 88111901 is built to Ingersoll Rand global technical standards, offering low initial pressure drop, high dust holding capacity and straightforward installation. It is a core consumable for routine maintenance of SSR M37–M45 compressors.

Applicable Standards
- ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors: performance testing
- ISO 16890 / EN 779 — General ventilation air filter classification
- 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 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 media turns black, dust loading is heavy, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and isolate: switch off the compressor main power, apply lockout/tagout (LOTO) and 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 wall and sealing face with a clean cloth. Never reverse-blow an old element with compressed air for reuse.
- Inspect the new element: verify part number 88111901 and check media, pleats, end caps and gasket for damage or aging.
- 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 and listen for air leaks at the filter housing; confirm normal operation.
FAQ
Q1: Is the 88111901 a genuine Ingersoll Rand part?
A: Yes. The 88111901 is a genuine Ingersoll Rand component manufactured to global technical standards and specified 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 any of the following applies: the media is visibly black or heavily loaded with dust; operating differential pressure reaches the 550 Pa alarm value; or the 4,000-hour / 8–12 month interval is reached.
Q4: What happens if the air filter element is too dirty?
A: A clogged element restricts intake, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, wearing rotors, bearings and shaft seals, which can increase oil carryover and even lead 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 should not be interchanged at will. Confirm the correct part number using the machine serial number.
