What is an Exhaust Filter?

Self-cleaning exhaust water filter is a water vapor separation device.

The air in the water system is prone to corrosion and damage to the equipment and components such as pumps, boilers, heat exchangers, refrigerators, etc., and the service life and efficiency are greatly reduced. It is not good to set the exhaust valve only at the highest point of the system. When the pressure is reduced, the gas dissolved in the water will re-form bubbles, especially a large amount of gas will be separated out before the pump. ^[1]

The self-cleaning exhaust filter uses the mechanism of air-water separation, sedimentation, and filtration. When the water in the cooling water, hot water and chilled water system enters the self-cleaning exhaust filter, the volume increases, the flow rate decreases sharply, and the air bubble separation in the water rises to the gas gathering area. After rising to the gas collection area, it is eliminated by the automatic exhaust valve. Circulating water with dirt in the filter. The dirt settles with the water flow. The dirt is accelerated after passing through the separation plate, and it quickly settles in the pollution storage area on both sides of the filter element. Open the drain valve regularly. After the air and dirt are separated, the clean water flows into the inlet of the pump through the filter element. Due to the small vibration of the filter element under the impact of the water pump and water flow, the dirt attached to the outside of the filter element can be shaken off to achieve self-cleaning. ^[2]

The self-cleaning exhaust water filter is a multifunctional system component, with automatic pressure difference alarm function, air and water separation function, and filtering function. The filter has strong self-cleaning ability, so it is not necessary to clean the filter often. Effectively remove impurities such as iron oxide scale, old scale, sludge and air in the water system, in order to give full play to and ensure clean water quality.

Vertical and horizontal are optional, occupying small space area;

Inlet and outlet angles are 0 °, 90 °, 180 °, 270 °. Arbitrary angle, flexible layout of machine room

With self-cleaning filter function, no need to open the cover to clean the filter

Can eliminate air bubbles and air dissolved in water, reduce system corrosion, protect water pump impeller;

Reduce system corrosion and protect pump impeller

Large dirt capacity

Low component resistance

Durant increase system resistance remains unchanged
