AUTOMATIC PRESSURE SWITCH Brand new, LEFOO automatic pressure switch for compressed air systems. Automatically turns electric motor ON or OFF at set values. Adjustable differential. Unloader port 1/4" OD copper tubing which allows compressor to start without back pressure load. Sturdy plastic housing. Manual off switch. Four port.
I have a dual stage pump And it run by a 230 vole 5 horse Motor 3450 rpm will this switch work on may compressor? Thanks Guy
A: If the amp draw is that of a real 5 Hp motor (22-25 amp) then it would be best to use a magnetic contactor. This switch will work by itself at that range, but will have a shorter life because of the current arcing on the contacts during make and break. If the amp draw is that of a 5 Hp Special (15 amps) then it should be fine.
