Condor MDR 1 pressure switch for compressors

Power pressure switches for compressors and pumping systems

The Condor MDR 1 is a compact and powerful pressure switch for compressors that can switch motors up to 2.5 kW directly. Its high-quality workmanship, precise switching points and sturdy die-cast aluminum housing ensure long-term reliable operation.

The proven MDR technology offers safety and quality, confirmed by extensive durability and vibration tests. With a maximum cut-off pressure of 11 bar, a motor switching capacity of 2.5 kW and protection class IP 44, the MDR 1 meets all requirements for modern control and regulation technology in compressed air technology.

Thanks to differential pressure adjustment, an optional operating hours counter, and a start-up relief valve (AEV), switching points can be precisely adjusted and operating times reliably monitored—for maximum operational reliability and durability in everyday industrial use.
