Tips: Ingersoll Rand Airend Rebuild Kit 42447169, a professional airend rebuild can restore the compressor efficiency to over 95%.
Product Introduction
The Ingersoll Rand Airend Rebuild Kit (Model 42447169) is designed specifically to repair the core components of IR air compressors. It provides a complete set of key components, including rotors, bearings, and seals, ensuring reliability and performance equivalent to OEM standards. Suitable for IR's mainstream stationary air compressor series (such as the SSR and XFE), this kit significantly reduces maintenance costs and extends equipment life. Designed to closely match original factory specifications, it supports efficient rebuilds and is compatible with high-pressure air requirements in a variety of industrial scenarios. At approximately 50% the price of a new airend, it is a cost-effective maintenance solution.

Product Features
1. Accurately restore compression efficiency
Pre-ground bearings and laser-calibrated seal grooves ensure an air gap tolerance of ±0.01mm after installation, preventing energy loss caused by internal leakage. Measured flow rate restoration reaches over 96% of new units.
2. Anti-degradation design extends service life
Seals made of perfluorocarbon rubber (FFKM) are resistant to high-temperature, acidic lubricants and offer a lifespan three times longer than standard NBR.
Bearings are pre-coated with molybdenum-based grease, providing additional protection during start-up and shutdown, reducing premature failure caused by dry friction.
3. Modular Repair Reduces Costs and Increases Speed
The kits are pre-packaged in the order of disassembly (e.g., rotor chamber assembly, bearing assembly, and end cap assembly). Engineers can replace each section individually, reducing a typical two-day repair to six hours.
Typical Application Scenarios
This rebuild kit is the preferred solution for the following high-load applications:
1. Automotive Manufacturing: Repairing unexpected bearing seizures during continuous operation of a spray paint line compressor.
2. Food Packaging: Preventing lubricant contamination and meeting FDA food-grade sealing standards.
3. Mining Equipment: Combating premature seal aging caused by dusty environments.
4. Pharmaceutical Manufacturing: Maintaining a stable air supply to meet... GMP Certification Requirements
Detailed Workmanship
The kit includes a brass washer with fine-adjustment scales to address axial play caused by thermal expansion.
1.Triple-lip shaft seal: 70% more oil leakage resistance than single-lip designs.
2.Preformed seal strip: Eliminates on-site cutting, ensuring a bubble-free end-face fit.
Authoritative Verification
Third-party laboratory testing demonstrates an L10 life of 13,000 hours for the bearings in this kit, exceeding the manufacturer's nominal value.
1. Compliance: All materials include a Safety Data Sheet (SDS) and comply with EU REACH regulations.
2. Performance Benchmark Verification: ISO 8573-1:2010 certified, with exhaust oil content ≤3 ppm after rebuild, exceeding the industry standard of 5 ppm.
Services Provided
1. Diagnostic Support: Free vibration analysis templates are provided to help predict airend failure points.
2. Global Express Delivery: 72-hour delivery from North American warehouses and 7-day delivery from Asia.
FAQ
Q1: Does the kit include a rotor? Do I need to purchase it separately?
The rotor is not included. This kit is designed for bearing and seal wear parts. Rotor damage requires a separate evaluation (free magnetic particle inspection guidance is provided).
Q2: After rebuilding, the compressor flow rate is still below standard. What could be the cause?
90% of the time, this is due to incorrect installation clearances. We recommend using the torque gradient wrench (included in the kit) and following the three-step tightening method.
Q3: Can it be used with compressors from other brands?
Strictly prohibit mixing! This kit is only compatible with Ingersoll Rand-specified models. Cross-use may result in an explosion risk.
