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

Product Overview

88171913 air filter element is a genuine Ingersoll Rand inlet filter element engineered for the UP5-11C-8 series small rotary screw air compressor. The element uses high-efficiency synthetic fiber media to block dust, dirt and particulate matter from entering the screw airend, protecting rotors, bearings and shaft seals from 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. Manufactured to Ingersoll Rand global technical standards, it offers low initial resistance, straightforward installation and reliable sealing.

Operating and Service Parameters

• 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 overall
• Service life: approx. 2,000–4,000 hours (6–12 months) under standard conditions; 1,000–2,000 hours in high-dust environments
• Shelf life: 36 months when sealed and stored in a dry, ambient-temperature environment

Standards

• ISO 5011 — inlet air 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 visual inspection shows darkening or heavy dust loading, 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 latches or nuts on housing 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. Never reverse-blow an old element with compressed air and reuse it.
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 fixing stud, ensuring the gasket seats correctly top and bottom without skewing or twisting.
7. Refit the cover: reinstall the cover and secure latches or nuts with no gap at the seal.
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 original part?
A: Yes. The 88171913 is a genuine Ingersoll Rand part manufactured to global technical standards and fits housing assembly 89243778.

Q2: Which compressors does the 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 machine serial number and we will match it precisely.

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 installs 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 when: (1) visual inspection shows darkening or heavy dust loading; (2) operating differential pressure reaches the 500 Pa alarm value; or (3) the 2,000–4,000 hour or 6–12 month interval is reached.

Q5: What happens if the air filter element is too dirty?
A: A clogged element causes insufficient intake, reduced discharge volume, higher specific power and increased energy consumption. In severe cases dust enters the airend, wearing rotors and bearings and aging shaft seals, which raises oil carryover and can ultimately scrap the airend.
