Feature:1. Manufatured by iron + copper + plastic material, this gas regulator is with guaranteed quality, and you can use it with confidence.2. High safety factor helps pressure switch with electric drive mode, which is durable to use.3. Air pressure controller is entitled with practical adoptability, which can keep its high performance for a long time.4. Used on the air compressor, pneumatic pressure switch can adjust the start and stop status of the air compressor. Meanwhile, the air compressor is stopped and rested by adjusting the pressure in the air storage tank.5. Given that such air regulator supports maintenance effect on the machine, it enables to prevent the machine from running all the time, not causing machine easily damaged.Specification:Item Type: Air regulatorModel: FB-31, three-phase 380V, sing holeMaterial: Iron / Copper / PlasticColor: BlackDrive Mode: ElectricRated Current: 20APressure Range: 0.8MPAWeight: Approx. 560 g / 19.8 ozDetails: Gas regulator is used on the air compressor to adjust the start and stop status of the air compressor. Air pressure controller can stop the air compressor to rest by adjusting the pressure in the air storage tank, which has a maintenance effect on the machine. During the commissioning of the air compressor factory, air regulator needs to be adjusted to the specified pressure according to customer needs, and then set a pressure difference, for example, when the compressor starts, it pumps up the air storage tank, and the air compressor stops or unloads while the pressure is 8kg. .Package List:1 x Pressure Switch
