PUHUI series - semi-automatic sewage filter sales champion product

Semi automatic sewage filterManufacturer's professional 'Puhui', HVAC system specific filters, semi-automatic sewage filters, champion products. This semi-automatic sewage filter is used in HVAC systems such as thermal pipelines, central air conditioning, heat exchange stations, boiler rooms, etc. The internal stainless steel is corrosion-resistant, and the shell is made of carbon steel pressure pipes, with good pressure bearing effect and long service life!

Working principle of semi-automatic sewage filter

Normal flushing: With the steering valve open for normal filtration, quickly open the drain valve, and the pressure inside the filter body will instantly decrease, causing the filter screen to vibrate, thereby loosening and shaking off impurities and dirt adhered to the filter screen, and discharging them from the drain outlet with the water flow.
Forced backwash: When cleaning and discharging normally, close the steering valve to allow the water flow to be filtered in the front section of the filter cartridge, and some of the water flow to backwash back to the rear section of the filter cartridge, washing away the impurities adhered to the filter cartridge and the dirt intercepted and stored inside the filter cartridge, and discharging them from the discharge outlet with the water flow.

Application range of semi-automatic sewage filter

The semi-automatic sewage filter combines the advantages of high-quality filtration from different water sources (sewage, reservoirs, rivers, lakes, etc.) with the simplicity of manual cleaning. This semi-automatic sewage filter is designed for a wide range of industrial, municipal, and irrigation applications. Heating pipelines, central air conditioning, etc. are used in the surrounding areas .....
The internal components of the semi-automatic sewage filter are made of stainless steel to withstand high loads of dirt and pressure. The cleaning of the main valve is also very simple. The operator opens the flushing valve and rotates the handle, and under high pressure, water covers the entire filter area to remove dirt, and the entire process only takes a few seconds.

Characteristics of semi-automatic sewage filter:

(1) Maintain free operation: The filter is cleaned and foreign particles are actively intercepted. Convenient sewage discharge.
(2) Continuous operation: Is it necessary to stop the line flow.
(3) The structure is simple.
(4) Compact size, its design saves space. In addition, it is easy to work with manuallyGL41HY type filterReplace with a semi-automatic sewage filter to facilitate the renovation of old pipelines.
(5) Superior performance price ratio: Intermittent filtration system, which reduces operating costs.
Connection method, flange connection. The flange grade standards are 1.0MPa, 1.6MPa, and 2.5MPa. As for higher pressure ranges and other international standards, please contact Pratt&Whitney Valve. The pressure range of the semi-automatic sewage filter is 0-2.5MPa.
