Type AA Strainer Angled Flow Body, Single Motorized Screen


Available in 3″ model only.  Providing hands-free operation, Type AA strainers employ a single, electric motor-driven rotating screen and a rigid scraper bar to remove solids from the surface of the screen when rotated. A solids collecting sump is also provided. Cleaning of the Type AA is initiated when the motor and the flush valve operator are actuated.

The cleaning cycle must be performed while the strainer is under positive pressure.  Type “AA” strainers are preferably installed in the vertical down-flow position as illustrated.

All Type “AA” strainers are shipped with Raised Face, ANSI B16.5 Class 150 Flanged Connections.
