D-2 air governor Replace KN18530 284358 275491 101474
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.
