Product Overview
The Filtaworx FW400 is a large-format automatic self-cleaning screen filter with 12,170 cm² of filtration area.
Filters in this range are also known as automatic backwash filters — the screen is cleaned in place by an automatic backwash cycle while flow continues uninterrupted.
The cleaning cycle, what triggers it and what it costs in water and time are set out in how automatic self-cleaning filters work.
