How to find the right Accessories & Compressors AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Accessories & Compressors

Pressure rating: The compressor and tank must reach and hold the operating pressure the horn maker specifies. Train and air horns sound weak or out of tune when they are under-pressurized.
Duty cycle: Choose a compressor whose rated duty cycle covers your refill needs, especially if you also run tools or tires off it. Running past the duty cycle overheats it and shortens its life.
Tank volume vs. horn consumption: Size the tank to the horn's air use; larger multi-trumpet train horns need a larger tank for usable blast length. A small tank gives only a short blast before pressure drops.
Pressure switch, relay and fusing: The compressor needs a pressure switch matched to its rating, a relay, and a fuse and wire gauge sized for its current draw. Compressors draw heavy current; wiring them without a relay and fuse is a fire risk.
Fittings and thread standards: Match thread type and size (commonly NPT in North American kits) across the tank, valves, gauge and lines. Mixed thread standards leak or will not seal.
Water management: Include a tank drain and mount the compressor intake filter away from road spray. Condensation and ingested water corrode tanks and kill compressors.

Viair: The most common onboard 12V compressor brand for horn and air-suspension setups.
HornBlasters: Train-horn specialist that sells matched compressors, tanks and valves.
Kleinn: Air horn and onboard air kits with matched components.
Wolo: Budget air horn compressors and replacement parts.

Usually not; small direct-drive horn compressors are not built to fill a tank to train-horn pressure, so get a rated onboard compressor and tank.
