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

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. It uses high-efficiency synthetic fiber media to block dust, dirt, and airborne particles from entering the screw airend, helping protect rotors, bearings, and shaft seals from wear and extending compressor service life.

The 88171913 element is installed inside air filter assembly 89243778 and is one of the core consumables in routine UP5-11C-8 maintenance. As an Ingersoll Rand intake filtration part, it is produced to Ingersoll Rand global technical standards and offers low initial resistance, straightforward installation, and reliable sealing.

Operating Conditions and Service Life

• Operating temperature: continuous -20°C to 80°C; short-term up to 100°C
• Relative humidity: ≤95% RH, no condensation
• Collapse pressure resistance: ≥ 2.5 kPa
• Service life: approx. 2,000–4,000 hours (about 6–12 months) under standard conditions; 1,000–2,000 hours in high-dust environments
• Shelf life: 36 months in original sealed packaging, dry ambient conditions

Standards Referenced

• ISO 5011 — intake filter performance testing for 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 2,000–4,000 hours or 6–12 months, whichever comes first.
• High-dust conditions (construction sites, woodworking shops, mining): every 1,000–2,000 hours.
• Replace immediately if the media turns black, dust loading is heavy, or 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 housing: release the end-cap clips or nuts on filter assembly 89243778 and remove the 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 reverse-blow old elements with compressed air and reuse them.
5. Inspect the new element: verify part number 88171913 and check the media for damage, pleat deformation, cracked end caps, or aged gaskets.
6. Install the new element: slide it onto the center stud, ensuring the gasket seats correctly top and bottom without skewing or twisting.
7. Refit the cover: reinstall the end cap, fasten clips or tighten nuts, and confirm there is no sealing gap.
8. Start-up check: start the compressor, listen for air leaks at the filter housing, and confirm normal operation.

FAQ for Buyers

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

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

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

Q4: How do I know when to replace the air filter element?
A: Replace it in three cases: visual inspection shows blackened media or heavy dust loading; operating differential pressure reaches the 500 Pa alarm value; or the 2,000–4,000 hour / 6–12 month interval is reached.

Q5: What happens if the air filter element is too dirty?
A: A clogged element restricts intake air, reduces discharge volume, raises specific power and energy consumption, and in severe cases allows dust into the airend, causing rotor and bearing wear, seal aging, higher oil carryover, and potentially airend failure.
