KBQ-04A series pressure difference switches can sense micro pressure change to conduct on-off action. This type of pressure difference switches is widely applied to flow control filters, air blowers and air valves of ventilating systems. It can also be applied to heater coil overheat protection and industrial cooling circuit frost protection. The product is visible and adjustable, and can visibly adjust the operation value of the pressure difference switch.
