Interruptor de presión de aire Dungs KS150A2-7 257842

Dungs KS150A2-7 257842 pressure switch is an adjustable differential pressure switch designed for use in air conditioning and ventilation systems. Its main function is to monitor the condition of air ducts, air filters and fans by turning on, off or switching the electrical circuit when the pressure in the system changes. The relay is equipped with an adjustment wheel that allows you to set the set pressure value. The mounting kit includes a differential pressure switch, mounting plate, connecting hose, mounting screws, hose connections, extension pipes and installation and operation instructions. The principle of operation consists in the reaction of the switching mechanism to changes in differential pressure: when the set pressure value is increased or decreased, the corresponding effect on the electrical circuit occurs.
