Les Hall Filter has been a longtime distributor of the Kraissl line of simplex and duplex strainers. These strainers are typically used for protecting equipment in pipeline service, with a wide range of flow capabilities. These cleanable strainers are available in cast iron, bronze, aluminum, steel, stainless steel and other special alloys, which ensures that we can provide a suitable strainer for any heavy duty application.

Unique to Kraissl strainers is a unique one-stroke valve operation on the duplex units, allowing for continuous flow transfer from one side to the other without interruptions. Duplex models also include a tapered plug valve with a metal-to-metal seat for long life in rough service, ensuring that your strainer will be rock solid for many years of operation.

If you think a strainer may be appropriate for your application, contact us to learn about the wide variety of options available on these high quality products.
