The Condor MDR1 pressure switch can be used for single phase compressors or as a pressure switch to provide a signal to the control circuit in a larger compressor. You can see just how the product works in the video below.
The MDR1 pressure switch is now supplied with differential kit as standard, this allows greater control over the cut out pressure of the switch.
On the underneath of the MDR1 switch there is an unloader valve with a 6mm push in connection. The function of the unloader valve is to remove the pressure from the piston of a compressor so that when it re-starts it can move freely and prevent the motor from stalling.
The MDR1 pressure switch is supplied with a delayed unloader valve (AEV 1S) as standard. If you need an unloader valve without delay (EV 1S), this can be ordered separately.
Cable glands are included with this product.
Pressure switches for other pressure ranges are available on request.
Please note, from Feb 2018 the MDR1 is now supplied with differential kit pre installed.
