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 captures dust, dirt, and particulate matter before it reaches the screw rotor, protecting bearings and oil seals from wear and extending compressor service life.
As an original Ingersoll Rand intake filtration component, the 88111901 is manufactured to Ingersoll Rand global technical standards. It combines low initial pressure drop with 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 filters for internal combustion engines and compressors: efficiency and dust capacity
- 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 & Installation
Replacement Interval
- Standard conditions: every 4,000 hours or 8–12 months, whichever comes first
- High-dust conditions (mining, construction materials, woodworking): every 2,000–3,000 hours
- Replace immediately if media turns black, shows heavy dust build-up, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and lock out: Turn off main power, apply lockout/tagout (LOTO), confirm the compressor has fully stopped.
- Open the filter housing: Loosen the retaining nut or clips and remove the cover.
- Remove old element: Pull out the old 88111901 element; 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 with compressed air.
- Inspect new element: Verify part number 88111901; check media for damage, pleats for deformation, end caps for cracks, and gasket for aging.
- Install new element: Slide the new element onto the center stud, ensuring the gasket seats evenly top and bottom without tilting or twisting.
- Refit the cover: Reinstall the cover and tighten nuts 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 original part?
A: Yes, the 88111901 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards, 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 unsure, provide your machine serial number and we will confirm the correct part.
Q3: How do I know when to replace the air filter?
A: Replace when: (1) visual inspection shows blackened media or heavy dust; (2) operating differential reaches the 550 Pa alarm; (3) the 4,000-hour or 8–12 month interval is reached.
Q4: What happens if the air filter is clogged?
A: A clogged filter restricts intake air, reducing discharge volume and increasing specific power and energy consumption. Severe clogging allows dust into the compressor, causing rotor and bearing wear, seal degradation, higher oil carryover, and potentially major compressor damage.
Q5: Can the 88111901 be interchanged with other SSR air filters?
A: No. Different SSR power classes use different filter dimensions and flow ratings. Always confirm the correct part number using the machine serial number.
