Product Description

The Kleinn 6270RC is a fully sealed, waterproof 12-volt air compressor built for reliable onboard air performance in demanding automotive environments. Rated at 150 PSI with a 25% duty cycle and a 1.9 CFM flow rate, it delivers consistent pressure recovery for air horn systems, compact train horns, and light-duty onboard air applications. Thermal overload protection automatically shuts down the motor if temperatures exceed safe operating limits, preventing permanent damage during extended use.

Designed as both a standalone upgrade and a direct replacement for Kleinn's HK3, HK3-1, HK4, and HK4-1 air horn kits, the 6270RC installs in most orientations and includes a remote intake Snorkel System to draw filtered air from inside the vehicle - a critical feature for under-truck or exposed frame rail mounting. The oil-less design requires no maintenance and the included stainless steel braided leader hose with built-in check valve ensures a durable, leak-free connection right out of the box.
