Air pressure switch on boilers, wall-hanging furnaces, and water heaters, which are a kind of home appliance with natural gas as an energy source. They are not only beautiful in appearance, and easy to use, but also small in size. Wall mounted on the wall of the family does not occupy a lot of use area. Meanwhile, the wall-hanging furnace can not only provide a large flow of constant temperature hot water for the family bath but also has a powerful family central heating function, which can meet the heating needs of multi-room.
Where is the air pressure switch boiler? This is a picture showing the air pressure switch in the gas boiler or water heater. In fact, the air pressure switch has negative pressure and positive pressure for options but most of them in the water heater is negative.
Besides, different installation requires different assemble shape, the following picture show the shapes on the market.
How air pressure switch on boiler works?
When the ignition switch of the gas water heater boiler enters the working state, the fan starts first to form a negative pressure difference in the combustion chamber, and the air pressure switch sends the instructions to the water pump. After the water pump starts, the water flow switch sends the instructions to the high-pressure discharge device. After the high-pressure discharge device starts, the instructions are sent to the gas-proportional valve, and the gas-proportional valve starts. Our GPS100 series wind pressure switch as a detection element, applied in the wall-hanging furnace, plays a vital role. It and the gas proportional valve and gas induction switch is interlocking control, the combustion chamber has a certain amount of negative pressure gas, and the proportional valve can work, when 5 seconds gas induction switch can not detect the exhaust gas discharge, the wind pressure switch can close the gas channel in time, to ensure that the gas does not leak, so as to protect personal safety.

About GPS100 Water Heater Air Pressure Switch
GPS100 series air pressure switches are specially designed for the OEM market and are typically used in boilers, wall-mounted furnaces, water heaters, HVAC, and other industrial control equipment. With custom pressure, positive pressure sensing, negative pressure sensing, and pressure difference sensing features. Equipped with our highly sensitive and highly reliable, and with UL, ENEC, CQC, LVD, and other multinational certifications of a micro switch, the micro switch can provide up to 16A 125/250VAC load control capacity, the switch meets the requirements of environmental protection materials. Besides, the boiler & water heater not only need air pressure switches but also need air pressure sensors, water pressure switches, water flow sensors, safety value, and so on.
Microswitch in the Air Pressure Switch
Generally, the microswitch is one of the parts of the air pressure switch and it should be a low operating force because the gas or the air can not provide a strong force for it. Other than that, other parameters are easy to find on some companies’ catalogs. Such as the color, circuits, rating, and so on. For us, the G5 is widely used on it, welcome to visit its product page.
All in all, the air pressure switch on boiler, on the water heater, or other device is easy to understand, if you wanna know how to wire it, welcome to contact us to know the details.
