水泵導流器也稱(導流過濾器、吸入式過濾器、泵入口過濾器)用於直接安裝在泵的入口處，具有特殊過濾設置能有效剔除雜物。

平直的整流板能夠爲泵提供平衡的水流，減少亂流對泵的衝擊和侵蝕，節省了泵的入口導流管，比傳統方式節省1/3空間，

具有取代90%彎管、丫型過濾器及整流管的功能，也能防止産生氣鎖現象。

Diffuser is also called (diversion filter, suction filter, pump inlet filter) for directinstallation at the inlet of the pump, with special filtering settings to effectively remove debris。

The straight rectifier plate can be The pump provides balanced water flow, reduces the impact and erosion of the turbulence on the pump, saves the pump's inlet diversion tube, saves 1/3 space than thetraditional method, and has the function of replacing 90% elbow, Y-type filter and rectifier tube It can also prevent air lock.
