Submerged Microfilter Series
Submerged Mechanical Filter for Aquaculture
Submerged mechanical filtration equipment for suspended-solids removal in commercial aquaculture, RAS systems and intensive fish farming.
Product Overview
Submerged Mechanical Filter for Aquaculture Solids Removal
Pursun Tech submerged mechanical filters separate suspended solids from circulating aquaculture water through a 316L stainless-steel filter screen and automatic intelligent backwash system. The equipment can serve as an independent mechanical stage within a RAS filtration system. Review the wider filtration equipment range for related components.

Technical FAQ
Submerged Mechanical Filter FAQ
Key information for product evaluation and model selection.
A submerged microfilter is a semi-submerged mechanical filtration unit that captures suspended solids on a rotating filter screen and restores screen capacity through automatic high-pressure backwash.
The Standard series uses a compact single-drum arrangement and includes models from 10T to 300T. The Open Inlet Classic series uses a larger enclosed open-inlet structure and includes 300T, 400T and 500T models.
Standard models include 10T, 20T, 30T, 50T, 100T, 150T, 200T and 300T. Open Inlet Classic models include 300T, 400T and 500T.
The supplied specification lists a 316L stainless steel filter screen and a stainless steel main body.
An intelligent dual-control system coordinates the motor and high-pressure water pump to clean the filter screen and maintain continuous solids-removal performance.
Regional configurations can be confirmed for 110V/60Hz, 220V/50Hz, 230V/50Hz or 240V/50Hz before ordering.
