Straight Pass Filter Strainer

Products Photos Catalog Straight Pass Filter Photos Catalog

The straight pass filter is an indispensable device for conveying medium pipelines.

It is mainly used in heating, air conditioning, HVAC, water supply systems and sewage pipes.

After the valve is installed in the pipeline, online sewage discharge can be achieved without closing the valve.

Operation Instructions

The steel welded filter is welded to the sewage pipe.

When the medium passes through the filter, the debris in the medium is passed to the outside of the filter cartridge.

When discharging sewage, the sewage valve can be opened online to flush the debris out of the body and discharge it to the designated location through the connecting pipe and the connecting hose.

After the sewage is discharged, the sewage valve can be closed.
