Ingersoll Rand 88171913 Air Filter Element | UP5-11C-8 Compressor

Product Overview

The 88171913 air filter element is a genuine Ingersoll Rand intake filter element built for the UP5-11C-8 series small rotary screw air compressor. Its high-efficiency synthetic fiber media captures airborne dust and particulate before it reaches the screw airend, helping protect rotors, bearings and shaft seals from abrasive wear and extending compressor service life.

The 88171913 installs inside air filter housing assembly 89243778 and is one of the most frequently replaced consumables in UP5-11C-8 routine maintenance. As an Ingersoll Rand intake filtration part, it is produced to Ingersoll Rand global technical standards and offers low initial pressure drop, straightforward installation and reliable sealing.

Standards Referenced

• ISO 5011 — inlet air filter performance testing 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 — air filter performance test methods (efficiency and resistance)

Maintenance and Installation

Replacement intervals

• Standard conditions: every 2000–4000 hours or 6–12 months, whichever comes first
• High-dust conditions (construction sites, woodworking shops, mining): every 1000–2000 hours
• Replace immediately if the media appears dark or heavily loaded, or if differential pressure reaches 600 Pa

Installation steps

1. Shut down and isolate power — switch off the compressor and confirm the unit has fully stopped.
2. Open the filter cover — release the cover clips or nuts on filter housing assembly 89243778 and remove the top cover.
3. Remove the old element — pull out the old 88171913 element and check whether the center gasket remains in the housing groove.
4. Clean the housing — wipe the inner walls and sealing surfaces with a clean cloth. Do not blow out and reuse an old element with compressed air.
5. Inspect the new element — verify part number 88171913, check media for damage, pleats for deformation, end caps for cracks and gasket for aging.
6. Install the new element — slide it onto the center mounting stud, ensuring the gasket seats correctly top and bottom without skewing or twisting.
7. Refit the cover — reinstall the cover and tighten clips or nuts so the seal is gap-free.
8. Start-up check — start the compressor, listen for air leaks at the filter housing and confirm normal operation.

FAQ

Q1: Is the 88171913 a genuine Ingersoll Rand part?
A: Yes. The 88171913 is a genuine Ingersoll Rand part produced to Ingersoll Rand global technical standards and fits filter housing assembly 89243778.

Q2: Which compressors does the 88171913 fit?
A: It is designed for the Ingersoll Rand UP5-11C-8 small rotary screw air compressor. If you are unsure whether it fits your unit, provide the serial number and we will match it precisely.

Q3: What is the relationship between 88171913 and 89243778?
A: 88171913 is the air filter element (consumable). 89243778 is the filter housing assembly (permanent part). The element is installed inside the housing; the housing is not replaced when changing the element.

Q4: How do I know when to replace the air filter element?
A: Replace when any of the following applies: (1) visual inspection shows dark, heavily loaded media; (2) operating differential pressure reaches the 500 Pa alarm value; (3) the 2000–4000 hour or 6–12 month interval is reached.

Q5: What happens if the air filter element is too dirty?
A: A clogged element reduces intake air, lowers discharge volume, raises specific power consumption and increases energy use. In severe cases, dust enters the airend and causes rotor, bearing and seal wear, higher oil carryover and potentially airend failure.
