Pressure Adjustment Range: Designed to control air compressor operation by maintaining system pressure, typically adjustable from 100–130 psi.
Mounting & Ports: Standard mounting dimensions and 1/8-inch NPT threaded ports for most heavy-duty truck and trailer applications.
Materials: Manufactured from corrosion-resistant, robust metal alloys to withstand harsh environments and vibration.
Application: Commonly installed on air brake-equipped vehicles, including Class 6-8 trucks, semi-trailers, and buses.

This is a heavy-duty, threaded D-2 style air compressor governor—directly interchangeable with Bendix/Haldex and related models (KN18530, 284358, 275491, 101474). It automatically cycles the air compressor on at a set "cut-in" pressure (typically 100–105 psi) and off at a set "cut-out" pressure (typically 120–130 psi).

Standardized port sizing and mounting make it a universal fit in commercial truck, trailer, and bus air brake systems. The governor ensures system safety and reliability by precisely managing compressor operation within OEM brake system requirements, and is widely available as both OEM and aftermarket replacement.
