Twist Flow Strainers
The Automatic Twist Flow filter (ATF) is a hybrid system consisting of a centrifugal separator and an inline filter. The fluid to be cleaned enters the housing tangentially (similar to a centrifugal separator) and accelerates down as a result of the tapered housing. The resulting spiral flow with its centrifugal force carries the coarsest contamination first to the inner wall of the housing. The smaller, less dense particles are filtered as the fluid passes through the element and exits the filter. Both the sedimented particles and those separated by the filter element finally collect at the bottom of the housing and are discharged periodically from the system by opening the backwash valve.
Filter is designed for filtration of solid particles from water or fluids similar to water. With filtration ratings between 200 μm and 3,000 μm, the ATF is particularly well suited for separating suspended solid particles, up to several grams per liter, from low-viscosity fluids.
