Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand intake filter engineered for SSR M37, SSR M37B, SSR M45 and MM45 series screw air compressors. Its high-efficiency synthetic fibre media blocks dust and airborne particles from entering the airend, protecting rotors, bearings and shaft seals from wear and helping extend compressor service life.
As an original intake filtration component for the SSR range, the 88111901 is manufactured to Ingersoll Rand global technical standards and combines low initial resistance, high dust-holding capacity and straightforward installation — a core consumable for routine maintenance of SSR M37 to M45 machines.

Standards & Compliance
- ISO 5011 — intake filter performance testing (efficiency and dust capacity)
- ISO 16890 / EN 779 — general ventilation air filter classification
- GB/T 14295 — air filters
- GB/T 6165 — air filter performance test methods (efficiency and resistance)
Installation & Maintenance
Replacement interval: every 4,000 hours or 8–12 months (whichever comes first) in standard conditions; every 2,000–3,000 hours in high-dust environments such as mining, building materials or woodworking. Replace immediately if the media is visibly blackened or heavily loaded, or if differential pressure reaches 650 Pa.
- Isolate and lock out the compressor main power (LOTO) and confirm the unit has fully stopped.
- Open the filter housing cover by releasing the retaining nut or clips.
- Remove the old element and check whether the centre seal ring has been left behind in the housing groove.
- Clean the housing with a dry cloth. Never reverse-blow and reuse an old element.
- Inspect the new element — verify part number 88111901, media integrity, pleat shape, cap condition and seal elasticity.
- Fit the new element over the centre stud, ensuring the seal seats evenly top and bottom without distortion.
- Refit the cover and tighten the nut or clips evenly for a gap-free seal.
- Start up and check for air leakage around the filter housing and confirm normal operation.
Frequently Asked Questions
Q1: Is 88111901 a genuine Ingersoll Rand part?
A: Yes. It is an original Ingersoll Rand component produced to the company's global technical standards for SSR M37/M45 series compressors.
Q2: Which compressors does it fit?
A: SSR M37, SSR M37B, SSR M45 and MM45 series screw compressors. If you are unsure, provide the machine serial number and we will confirm exact fitment.
Q3: How do I know when to replace the element?
A: Replace when the media is visibly blackened or heavily loaded, when operating differential pressure reaches the 550 Pa alarm value, or when the 4,000-hour / 8–12 month interval is reached.
Q4: What happens if the element is left too long?
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, seal degradation and elevated oil carryover.
Q5: Can it be interchanged with other SSR air filters?
A: Filter dimensions and rated flow differ across power ranges, so elements are not freely interchangeable. Always confirm the correct part number using the machine serial number.
