The role of the filter is to remove suspended matter and particles in the water, reduce turbidity, purify water quality, and reduce system dirt, bacteria, algae, rust, and corrosion, to purify water quality and protect the normal work of other equipment in the system. Stainless steel strainer is an indispensable device on the pipeline transporting media, usually installed in other equipment at the import end of the equipment. After the medium to be treated passes through the cartridge of the stainless steel strainer, its impurities are blocked. When cleaning is needed, just take out the removable cartridge and re-install it after treatment, therefore, it is extremely convenient to use and maintain.

What are the features of our stainless steel Y-filters?


Filters are available with threaded (NPT/BSP/BSPT) or socket weld inlet/outlet connections. The stainless steel strainer body meets applicable ASME standards. The filter is equipped with a threaded cap and sealed with a flat gasket. 304SS perforated screens are standard. It is equipped with a discharge/exhaust connection with a plug as standard. Its large screen area and properly proportioned filter chamber minimize initial pressure drop while maximizing the time between cleanings. The stainless steel strainer has a machine tapered seat for perfect installation of removable filter screens with a discharge plug that can be replaced with an optional ball valve for in-line discharge of dirt, limescale, etc. Stainless steel filter has a compact and reasonable structure design, small footprint, and flexible and convenient installation and movement.

Stainless steel filter achieves automatic backwashing through its retrieval and strain function, which can cope with unstable water quality fluctuations without manual intervention. 


Stainless steel filter has few wearing parts, no consumables, low operation and maintenance costs, and simple operation and management. The stainless steel strainer operates precisely and can flexibly adjust the backwashing differential pressure time and time setting value according to different water sources and filtration precision. During the backwashing process of the stainless steel strainer, each screen is backwashed in turn; to ensure safe and efficient cleaning of the screen, while other screens are not affected and continue to filter.
