A402 Pressostat d'air pour chauffe-eau (0,5 psi)

HVAC Air Pressure Switch Description

The A402 HVAC air pressure switch belongs to our A4 series family which is high-quality and high precision. It uses the unibody construction design to replace the traditional microswitch construction type, which has better precision, longer life, and is more stable. The accuracy for the A4 HVAC air pressure switch series is ±3Pa, which is a high level on the market.

Meanwhile, it not only has a wide working pressure range that is from 40 to 500Pa, so it can meet many different devices’ requirements. As well as it has good performance in working temperature, which is from -40 to 110℃. So, the switch will not easy to be affected by the environmental temperature.

Besides, it also has a long operating life, it has 250000 cycles of electrical life and 1000000 cycles of mechanical life at least. What’s more, we not only have the air pressure switch but also have the air pressure sensors, which can detect different places’ valves at the same time.  For more REGAL pressure & flow switch sensor products, please click the link or contact us to get more details.
