Ingersoll Rand 89243778 Air Filter Housing Assembly | UP5-11C-8 Intake Filter

Product Overview

The 89243778 air filter housing assembly is a genuine Ingersoll Rand intake filter housing component built for the UP5-11C-8 series of small rotary screw air compressors. The assembly comprises the filter housing, end cover, seals and mounting interface, and is designed to work with filter element 88171913 to form a complete intake filtration system.

Produced to Ingersoll Rand global technical standards, the 89243778 aligns precisely with the UP5 series intake piping for a reliable, leak-free seal that protects the screw airend from dust wear.

• Filter class: F5 (medium-efficiency pre-filter)
• Dust holding capacity: approx. 0.15–0.20 kg
• Beta ratio: β₅ ≥ 100

Flow and Pressure Drop

• Rated air flow: approx. 1.5–2.0 Nm³/min (UP5-11 models)
• Initial pressure drop: approx. 150–200 Pa (with new element)
• Operating differential range: 200–400 Pa
• Alarm / final resistance: 500 Pa alarm; 600 Pa final
• Energy impact: every 100 Pa increase in intake pressure loss raises specific power consumption by approx. 0.5%

Construction and Mounting

• Housing dimensions: approx. φ120 × 150 mm (reference value)
• Intake connection: approx. 1.5"–2" (threaded / flanged)
• Mounting: screw-fixed / clip-on, vertical installation
• Sealing: gasket between housing and end cover; center bore seal for the element
• Housing material: engineering plastic (PA/PP) or die-cast aluminium alloy
• End cover: engineering plastic with clips or nut
• Seals: NBR O-rings, oil and ageing resistant
• Mounting bracket: metal or plastic base
• Fasteners: mounting nuts and washers included

Operating Conditions and Service Life

• Operating temperature: -20°C to 80°C
• Relative humidity: ≤95% RH
• Pressure resistance: housing withstands 10 kPa negative pressure without deformation
• Service features: removable for cleaning and reuse; element can be replaced without removing the housing
• Housing service life: matches the compressor, generally ≥10 years under normal use
• Seal inspection: check O-rings at every element change; replace if hardened or deformed
• Storage life: 60 months in sealed packaging, dry conditions at room temperature

Standards Referenced

• ISO 5011 — inlet air filter performance testing for compressors
• ISO 16890 / EN 779 — air filter classification
• GB/T 14295 — air filters
• GB/T 6165 — air filter performance test methods

Maintenance and Installation

Replacement Intervals

• Filter element 88171913: every 2,000–4,000 hours or 6–12 months
• Housing: no scheduled replacement; replace as a unit if cracked or damaged
• Seals: inspect at every element change; replace if deformed or aged

Installation Steps

1. Shut down and isolate: switch off the compressor and confirm it has fully stopped.
2. Remove the end cover: release the clips or nuts and lift off the cover.
3. Extract the old element: pull out the used 88171913 element.
4. Clean the housing: wipe the inner walls and sealing faces with a clean cloth to remove dust and debris.
5. Inspect seals: check the O-ring between housing and end cover; replace if aged or deformed.
6. Fit the new element: seat the new 88171913 element in the housing center.
7. Refit the cover: replace the end cover and secure clips or nuts.
8. Full assembly replacement (if required): if the housing is cracked or damaged, remove the intake pipe bolts, take off the complete 89243778 assembly, fit the new unit and reconnect the piping.
9. Start-up check: run the compressor and listen for air leaks at the connections.

FAQ

Q1: Is 89243778 the housing assembly or the filter element?
A: 89243778 is the housing assembly (housing, end cover and seals), not the element. The matching element is 88171913. For routine servicing, order 88171913 only — the housing does not need replacing.

Q2: Which models does 89243778 fit?
A: It fits the Ingersoll Rand UP5-11C-8 small rotary screw compressor. If you are unsure, provide the machine serial number and we will confirm.

Q3: What is the relationship between 89243778 and 88171913?
A: 89243778 is the housing assembly; 88171913 is the element that fits inside it. The housing is a long-life component; the element is a consumable replaced at service intervals.

Q4: Does the housing need periodic replacement?
A: Under normal use, no. Replace the complete 89243778 only if the housing cracks, deforms severely, the thread strips, or the sealing face is damaged.

Q5: How do I know when to replace the housing?
A: Replace it if: (1) the housing is cracked or broken; (2) the cover clips are broken and cannot seal; (3) the intake connection thread is damaged and leaking; or (4) the sealing face is worn and no longer seals.
