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

Product Overview

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

As an original Ingersoll Rand inlet filtration assembly, the 89243778 is manufactured to Ingersoll Rand global technical standards, ensuring precise alignment with the UP5 series compressor intake piping, reliable sealing without leakage, and effective protection of the screw airend from dust wear.

Technical Parameters

Filtration Performance (with element 88171913)

This product is a housing assembly; filtration performance is determined by the matching element 88171913.

• Filtration rating: approx. 5 μm
• Filtration efficiency: approx. 98% @ 5 μm
• 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 (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 at 600 Pa
• Pressure drop vs. energy: every 100 Pa inlet pressure loss increases specific power by approx. 0.5%

Dimensions and Installation

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

Materials

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

Operating Conditions

• Operating temperature: -20°C to 80°C
• Relative humidity: ≤95% RH
• Pressure resistance: housing withstands 10 kPa negative pressure without deformation
• Serviceability: removable for cleaning and reuse; element can be replaced without removing the housing

Service Life and Maintenance

• Housing service life: matches machine life, generally ≥10 years under normal use
• Seal replacement: inspect O-rings at every element change; replace if aged
• Shelf life: 60 months in original sealed packaging, dry ambient temperature

Standards

• ISO 5011: inlet air cleaner performance testing
• 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

• Air filter element 88171913: every 2,000–4,000 hours or 6–12 months
• Housing: no scheduled replacement; replace as a unit if damaged or cracked
• O-rings: inspect at every 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. Remove end cover: release the cover clips or nuts and take off the top cover.
3. Remove old element: withdraw the used 88171913 element.
4. Clean housing interior: wipe the housing inner wall and sealing face with a clean cloth to remove dust and debris.
5. Inspect O-rings: check the seal between housing and end cover; replace if aged or deformed.
6. Fit new element: place the new 88171913 element into the housing center position.
7. Refit end cover: reinstall the cover and secure clips or tighten nuts.
8. Full assembly replacement (if needed): if the housing is cracked or damaged, remove the intake piping bolts, take off the complete 89243778 assembly, fit the new assembly and reconnect piping.
9. Start-up check: start the compressor and check connections for air leakage noise.

FAQ

Q1: Is 89243778 the housing assembly or the element?
A: 89243778 is the air filter housing assembly (housing, end cover, seals), not the element. The matching element is 88171913. When replacing the element, 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 unsure, provide the machine serial number for confirmation.

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 part (machine life), while the element is a consumable (periodic replacement).

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

Q5: How do I know when to replace the housing?
A: Replace the housing if: ① the housing is cracked or broken; ② end cover clips break and cannot seal; ③ inlet threads are damaged and leak; ④ the sealing face is worn and cannot maintain a seal.
