Overview
The HornBlasters 20 Gallon 7 Port Air Tank with Fitting Kit (part number H/BTA-2008H-862) is a 20 gallon air tank with seven high-flow ports for train horns, air suspension and air tools.
The tank is made for high-flow applications such as train horns and air suspension systems, and it provides plenty of air to run air tools. It has seven ports: five 1/2 inch ports, one 3/4 inch port and one 1/4 inch port, to prevent bottlenecking.
The tank is made in the USA and meets SAE J10 and FMVSS 121 specifications. It has a semi-gloss black powder coat outside and an interior coated with a rust inhibitor to resist corrosion.

Planning the air system
A tank is the storage side of a compressed air system, so its size and ports matter as much as the compressor. A larger tank holds more air between compressor cycles, which steadies pressure when several tools or horns draw at once. Plan the layout so the lines to each port are short and direct.
Pressure safety starts with the valves. A pressure switch sets when the compressor runs, and a blow-off valve should be rated above that setpoint so the system relieves before components are damaged. Check the drain valve on a regular basis, since moisture collects in the bottom of any tank. Mount the tank securely and measure the space before you commit to a location.
- Measure mounting space before cutting or drilling
- Drain moisture from the tank regularly
- Inspect fittings and lines for leaks

Vehicle fitment
The HornBlasters 20 gallon air tank is not vehicle-specific. It serves any mobile air system, from train horns to suspension.
No tank dimensions are given, so measure the space available before choosing a mounting location, and check HornBlasters’ specifications for mounting points.
Installation notes
HornBlasters advises installing a safety blow-off valve in any air system to keep it from over-pressurizing and damaging other components. It suggests a valve rated 25-35 PSI higher than the maximum pressure of the pressure switch: for example a 175 PSI blow-off valve for a 150 PSI system, and a 150 PSI blow-off valve for a 120 PSI system.
