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

Product Overview

89243778 is the genuine Ingersoll Rand inlet air filter housing assembly engineered for the UP5-11C-8 series small rotary screw air compressor. The assembly includes the filter housing, end cover, sealing components, and mounting interface, and it is designed to work with air filter element 88171913 to form a complete inlet filtration system.

Manufactured to Ingersoll Rand global technical standards, the 89243778 housing aligns precisely with the UP5 series intake piping, delivers reliable leak-free sealing, and helps protect the screw airend from dust-related wear.

Key Specifications

Filter Performance (with element 88171913)

Filtration performance is determined by the paired element 88171913.

• Filtration rating: approx. 5 μm
• Filtration efficiency: approx. 98% @ 5 μm
• Filter class: F5 (medium-efficiency pre-filtration)
• Dust holding capacity: approx. 0.15–0.20 kg
• Beta ratio: β₅ ≥ 100

Flow & Pressure Drop

• Rated air flow: approx. 1.5–2.0 Nm³/min (for UP5-11 models)
• Initial pressure drop: approx. 150–200 Pa (with new element)
• Operating differential range: 200–400 Pa
• Alarm / final resistance: alarm at 500 Pa; final resistance 600 Pa
• Energy relationship: each additional 100 Pa inlet pressure loss raises compressor specific power by approx. 0.5%

Dimensions & Installation

• Housing dimensions: approx. φ120 × 150 mm (reference)
• Inlet connection: approx. 1.5"–2" (threaded / flanged)
• Paired element: 88171913
• Mounting: bolt-fixed / clip-on, vertical installation
• Sealing: seal ring between housing and end cover; element seals against housing center bore

Materials

• Housing: engineering plastic (PA/PP) or die-cast aluminum alloy
• End cover: engineering plastic with clips or nut
• Seals: NBR (nitrile rubber) seal rings, oil and ageing resistant
• Mounting bracket: metal / plastic base
• Fasteners: mounting nuts and washers included

Operating & Service Conditions

• Operating temperature: -20°C to 80°C
• Relative humidity: ≤95% RH
• Pressure resistance: housing withstands 10 kPa negative pressure without deformation
• Service features: removable and reusable; element can be changed without removing the housing
• Housing service life: matches compressor life, typically ≥10 years in normal use
• Storage life: 60 months in sealed original packaging, dry at room temperature

Standards Referenced

• ISO 5011 — inlet air cleaner 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 & Installation

Replacement Intervals

• Air filter element 88171913: every 2,000–4,000 hours or 6–12 months
• Housing: no scheduled replacement; replace only if damaged or cracked
• Seals: inspect at each element change; replace if deformed or aged

Installation Steps

1. Shut down and isolate: switch off compressor power and confirm the unit has fully stopped.
2. Open the filter end cover: release the cover clips or nut and remove the top cover.
3. Remove the old element: pull out the used 88171913 element.
4. Clean the housing interior: wipe the inner walls and sealing faces with a clean cloth to remove dust and debris.
5. Inspect the seal ring: check the seal between housing and end cover; replace if aged or deformed.
6. Fit the new element: seat the new 88171913 element in the housing center position.
7. Refit the end cover: replace the cover and secure the clips or tighten the nut.
8. Full assembly replacement (if required): if the housing is cracked or damaged, remove the intake piping bolts, take off the complete 89243778 assembly, fit the new unit, and reconnect the piping.
9. Start-up check: start the compressor and check all connections for air leakage.

FAQ

Q1: Is 89243778 the housing assembly or the filter element?
A: 89243778 is the filter housing assembly (housing, end cover, and seals), not the element. The paired element is 88171913. For routine servicing, order only 88171913; the housing does not need to be replaced each time.

Q2: Which models does 89243778 fit?
A: It fits 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 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 durable component matched to the compressor, while the element is a consumable replaced at 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 complete assembly?
A: Replace the housing if: ① it is cracked or broken; ② the end cover clips are broken and cannot seal; ③ the inlet thread is damaged and leaking; ④ the sealing face is worn and cannot maintain a seal.
