Products Description
Air Pressure Switches
LF12 is three phase pressure switch, used for air compressor and water pump to regulate pressure between two preset values. It is available with an unloader value, which prevents compressor from starting under load and an On-Off knob for manual cut off the compressor or pump. A four port manifold style is available, which makes easy mounting of other parts for air compressor, like valve and gauge. LF12 is available with thermal relay for overload protection.The relay will cut off the motor power timely to prevent the motor from burning when motor is overloaded.
