A53G SPDT Air Pressure Switch
A53G gas boiler air pressure switch is a negative type switch that has 3 187# terminals with a customizable pressure range for use in a boiler, water heater, commercial air conditioner, or other VAV systems.
Gas Boiler Air Pressure Switch Description
The A53G gas boiler air pressure switch has 2 differential pressure air tubes, one is high pressure and the other one is low pressure. You can customize it according to your requirement and we also have the universal water heater pressure switch, please contact us if you to see more.
The A5 series is a new design type that uses the leaf spring to replace the traditional spring construction. This kind of new design can eliminate the effect of temperature so that these air pressure switches have higher precision and reliable performance than the traditional types. We also got the letters patent for it.
Meanwhile, this series of switches are totally sealed, which can resist water and dust. So, it is especially suitable for a hostile environment that is wet and dusty because it can work well for a long time. Welcome to test our samples.
