Restrainer (support) Basket
Used to fully support a filled filter bag, reducing chance of rupture once filled. The standard design is made of 316SS and has 9/64" perforations. The bottom of the filter bag should extend all the way to the bottom of the restrainer basket. We also offer mesh lined versions to "convert" filter housings into large pipeline strainers. For coarse filtration applications this may be a better alternative than mesh filter bags.

Hold Down Ring. Used for applying downward pressure onto the filter bag for better sealing with the restrainer basket. Hold down rings are not required for all filter housing styles and are not used for SNAP-RING™ filter bags.
Also referred to as "filter bag locks" ensure proper positioning of the filter bag within the restrainer basket. Bag positioners should be used for all applications that have potential for back pressure (otherwise causes the filter bag to move a lot within the restrainer basket). They are required for ACCUGAF™, PROGAF™ and LOFCLEAR™ filter bags.
