Overview
The Kleinn Train Horns HK7 is a complete triple train horn package with a 150 psi, 100% duty sealed air system. It includes Model 230 train horns, a Model 6350 compressor, a 2.5 gallon air tank, and the wiring, switches and mounting hardware needed for a full install.
The Model 230 horns use a flat-rack design that needs 40% less clearance than 500 Series train horns. The trumpets separate from the mounting brackets, which helps in tight spaces where full-size train horns would not otherwise fit.
Key features
- Triple train horn configuration with Model 230 horns
- 100% duty sealed air system rated at 150 psi
- Flat-rack design requiring 40% less clearance than 500 Series train horns
- Trumpets separate from mounting brackets for tight installations
- Includes compressor, 2.5 gallon tank, tubing, switches and remote mount intake filter
- It is a universal fit kit, so it is not built for a specific year, make or model.
Air system maintenance
An air horn system stores compressed air and releases it through the horns when the switch is pressed, so the tank, compressor and lines all affect how reliably the horns sound. Moisture is the main enemy in a system like this. It gets into the tank over time and can reach the valves and horns, which is why draining and checking the air lines matter more than many owners expect.
Route the air lines away from exhaust heat and sharp edges, and secure them so they do not rub against the frame or body. Check the safety valve and pressure switch periodically, since they protect the system when pressure runs high. Before any service, drain the tank fully and let the system depressurize, because the tank holds stored compressed air even when the engine is off.
- Route air lines away from exhaust heat
- Check fittings for leaks with soapy water
- Confirm the cab switch wiring is secure
