Ingersoll-Rand Air Compressor Inlet Filter (32170953)

This inlet filter assembly includes a 10 micron filter element and the outer assembly, designed for use on Ingersoll Rand compressors in the 2340, 2475, TS4N5, and 2200L5 series. The 1″ stem thread ensures straightforward installation in compatible housings. Its focus on filtration efficiency helps reduce particulates reaching the compression chamber, potentially extending service intervals and maintaining better air quality for tooling and finish work. Maintenance involves inspecting the filter element and replacing it as needed to sustain performance.
XYZIL Air Compressor Inlet Filter with Element 32170953

XYZIL offers a standard 32170953 inlet filter element compatible with a broad range of Ingersoll Rand models, including 2340S5-AS, 10CGT, 10FGT, 10XGT, and 2475 variants. The assembly supports multiple pump configurations, ensuring a practical replacement option for several stationary reciprocating compressors. This compatibility makes it a versatile choice for workshops with mixed fleets. Regular checks for seal integrity and element condition help maintain filtration performance and minimize intake contaminants.
Viair 3/8″ NPT Intake Air Filter Muffler Assembly

The Viair muffler assembly features an aluminum housing with a 3/8″ NPT male thread, plus a removable cap to replace the filter element easily. This design is suitable for portable compressors and vehicles that require quiet operation alongside filtration. The combination of a muffler and filter reduces intake noise while providing a barrier against dust and moisture entry, which supports compressor longevity in dusty or outdoor environments.
Replacement Air Intake Filter Assembly for Husky (PRO-EDGE)

PRO-EDGE’s Husky replacement air intake filter assembly emphasizes durable carbon steel construction suitable for indoor or outdoor use. With a 1/2″ MNPT thread and a compact enclosure measuring 3.56″ height by 3.25″ diameter, this unit offers a robust fit for smaller to mid-sized compressors. The design supports straightforward maintenance and replacement of the filter element, helping to preserve compressor efficiency in challenging environments with dust, humidity, or temperature fluctuations.
Replacement Carbon Steel Air Intake Filter Assembly for Ingersoll Rand 32170953

Also from PRO-EDGE, this carbon steel intake filter assembly is designed for 1″ MNPT connections and Ingersoll Rand 32170953 deployments. The enclosure stands 4.0″ tall with a 6.0″ diameter, delivering a sturdy housing that can withstand harsh environments. Its steel construction offers durability in shop settings, wind, and rain exposure, while the filter element helps prevent dust and particulates from entering the compressor’s intake path.
Buying Guide: Key Considerations for Air Filter Assemblies
When selecting an air filter assembly for an air compressor, consider compatibility, filtration efficiency, durability, and maintenance ease. First, verify model compatibility and thread size (MNPT vs. FPT) to ensure a proper fit with your unit. In critical service areas, a lower micron rating (such as 10 microns) provides finer filtration, but assess whether your environment warrants absolute filtration or a balance between flow and protection.
Durability matters in shop conditions. Steel or carbon steel housings offer ruggedness for outdoor or workshop use, while aluminum housings provide a lighter option with corrosion resistance. For portable compressors, integrated muffler elements can simultaneously reduce intake noise, contributing to a quieter work environment. Consider whether the design supports straightforward element replacement without disassembly or special tools, as this directly affects maintenance downtime.
Maintenance strategy should include a regular inspection schedule for filter elements, seals, and housings. Build a replacement cadence based on operating hours, ambient conditions, and the presence of dust or moisture. When possible, select assemblies with standard filter elements that are widely available to avoid extended downtime waiting for specific parts. Finally, assess the total cost of ownership, including initial purchase, replacements, and potential energy efficiency implications from improved air quality inside the compressor.
Across the five highlighted options, users gain access to compatible, durable, and service-friendly assemblies that suit a variety of compressors—from compact Husky and VIAIR units to larger Ingersoll Rand models. Careful matching of thread sizes, material construction, and maintenance access will yield dependable performance and longer service intervals in demanding environments.
