Bridge-type water filters offer the following advantages compared to other types of water filters:

　　The unique structure of the bridge-shaped orifice makes it less prone to blockage by gravel. According to tests by Germany's Nord Company, the porosity of traditional water filters is reduced by 40% when filled with gravel, whereas the bridge-style filter only sees a decrease of 10%. Therefore, the bridge-style filter has...GoodExcellent water purification capabilities. The well provides clean, sand-free water after desanding and well cleaning.

　　2. The special hole structure of the water filter enhances its mechanical strength. Therefore, it boastsGoodThe mechanical strength.

　　3. Based on customer requirements, wells can be coated with various corrosion-resistant layers, thereby extending their lifespan.

　　4. The bridge-type water filter system is made from punched steel plates and rolled, resulting in lightweight and cost-effective.

　　5. Multiple connection methods are available, making the downstream operation convenient.

　　6. We can adjust the gap of the bridge openings according to customer requirements, ensuring a satisfactory porosity for the bridge.

　　7. Offer bridge water filters in any diameter upon customer request.GreatConvenience for users is provided locally.
