Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand intake filter element engineered for SSR M37, SSR M37 B, SSR M45, and MM45 series screw air compressors. Its high-efficiency synthetic fiber media blocks dust, particles, and airborne contaminants from entering the screw airend, protecting the 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 combines 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 (efficiency and dust capacity)

- 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): every 2,000–3,000 hours
- Replace immediately if visual inspection shows dark media, heavy dust accumulation, or 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: release the retaining nut or clips and remove the cover.
- Remove the old element: pull out the used 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 skew or twist.
- Refit the cover: reinstall the cover and tighten nuts 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 original part?
A: Yes. The 88111901 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and fits Ingersoll Rand 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 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, 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 element is 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, causing rotor and bearing wear, oil seal degradation, higher oil carryover, and potentially airend failure.
Q5: Can the 88111901 be interchanged with other SSR elements?
A: SSR elements for different power ranges have different dimensions and flow ratings and are not freely interchangeable. Always confirm the correct part number using the compressor serial number.
