Feature: 1. Pressure switch is made of iron + copper + plastic material, easy to use in the practical life. 2. 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. 3. With a maintenance effect on the machine, air regulator can prevent the machine from running all the time, not causing the machine to be easily damaged. 4. Equipped with a high safety factor, such air regulator supports electric drive mode, durable to use. 5. Air pressure controller is entitled with practical adoptability, which can keep its high performance for a long time. Specification: Item Type: Air regulator Model: FB-30, single-phase 220V, sing hole Material: Iron / Copper / Plastic Color: Black Drive Mode: Electric Rated Current: 15A Pressure Range: 0.8MPA Weight: Approx. 314 g / 11.1 oz Details: Pressure switch is used on the air compressor to adjust the start and stop status of the air compressor. Air regulator 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, it 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. Single-phase 220V is the direct grounding system of the transformer center point, and the voltage of each live wire to ground (or neutral) is 220V.. Package List: 1 x Pressure Switch
