Cylindrical Filter /Strainer Baskets are designed from basic materials: expanded metal and perforated metal. Each material has its own flow rates and individual characteristics making it a “best fit” for particular engineering requirements. For example, perforated metals can be selected with round holes, square holes, or any other shape required based on size or shape of the particulate that needs to be strained or filtered. Expanded metal and perforated metal filters offer superior rigidity and durability to wire cloth filters. For filters that require intricate bends and pleats to achieve proper performance characteristics, and where durability is less of a concern.

In some applications, filter design requires a mix of materials for support or to develop a protective underlying or outer structure of expanded or perforated metal or a coarser mesh that guards delicate pleated interior components.
Typical metal filter shapes, closures & end styles
Metal filters as custom designed to fit your specific application can be formed using a variety of techniques. The specifics of your filtration requirement – particles size, GPM flow rate, contact liquid as well as the physical space limitations intowhich the filter must fit all affect the construction type and the filter end formation.

The following are typical construction variations:
Pinched End Strainer
Bag Fold Strainer
Square fold end Strainer
Flush Bottom Strainer – this strainer could be fitted with a wire cloth bottom or solid metal end cap
Inverted Bottom Strainer
Cone Shaped Strainer
Truncated Cone Strainer
Rectangular Strainer
Pleated Strainer
Cylindrical Straine
