Brand new heavy duty, 26 Amp LEFOO 95-125 PSI air compressor, pressure switch, control valve with a single port connection manifold. The switch listed is a universal replacement pressure switch that replaces brands such as Furnas , Square-D and more. This switch is equipped with an unloader valve, on / off lever, and a single port mounting manifold. This is similar to the regular single port pressure switch, but this switch is equipped with heavy duty 26Amp contacts to provide a longer lasting switch in demanding applications.
The unloader equipped on this switch is used to unload the air pressure off the head of the compressor when the compressor shuts off, this way when it starts there is no pressure on the piston and the compressor is able to start load free. This valve usually has a 1/4" plastic or copper line that runs to the check valve or the head of the compressor. If your compressor does not have a unloader line then this valve can be left not hooked up and the pressure switch will still function properly.
This switch can be used on a single stage or two stage compressor as long as the amperage is less than 26 amps on 120 volt or 20 amps on 240 volt, however if this is being used with a magnetic starter on a larger compressor the amperage does not matter, in this case it is just used to turn the starter on & off at the set pressure.
This switch comes pre set to turn the compressor on at 95 PSI and shut off at 125 PSI. This can be adjusted to any pressure within the factory minimum and maximum set points listed below. We have a picture showing the diagram for pressure adjustment.
Minimum On: 35 PSI
Pressure Differential: 30-40 PSI
1/4" Compression Unloader Valve Connection
1/4" Female NPT Tank Connection
Max Amps: 26 Amps at 120 Volt / 20 Amps at 240 Volt
