Holset Air Compressors

Fleet Products stocks Holset air compressors engineered for high-output performance in truck brake systems. Ideal for Cummins-powered applications, Holset compressors are built for durability, pressure efficiency, and serviceability. ALL QE MODEL COMPRESSORS REQUIRE A 4 LINE DRYER 065647WL-G EXTRA LINE BY ITSELF PART 500457.

Suffixes like D, M, and C identify the engine platform—Detroit Diesel, Mack, and Cummins—and when followed by E, they indicate an E-Type unloader configuration for that engine series. Meanwhile, prefixes such as SS (Super Single), ST (Super Twin), and QT (Quiet Economy) define the compressor family before the model number.
