Fluid Straining Systems

As a leading provider of fluid straining systems, Hellan Strainers remove all types of solids (such as algae, zebra mussels, sand, grit, debris, machine cutting chips, etc.) from various fluids. They are extremely popular due to their reliability, efficient operation and cost savings. Instead of trapping solids like conventional basket strainers (which necessitate frequent basket removal for cleaning), the Hellan Strainer discharges solids from the flow without disassembly. This reduces operational and maintenance costs and permits continuous flow of fluids. 

Online Cleanable / Automatic Strainers


Online Cleanable Strainers are designed for applications where automated cleaning cycle is preferred. Automated Strainers reduce the manual process of cleaning the baskets.

Hellan Fluid Systems, a leading provider of self-cleaning fluid strainers, offers strainers that are cast in sizes from 1 1/2″ to 20″ and fabricated in 2"- 60" sizes. The nature of the fluid to be strained determines the material of the casting. Cast iron models are most common for freshwater applications. Cast steel can be used for higher pressure or where water hammer occurs. Stainless steel is used for highly corrosive fluids and bronze is used for seawater applications. Since the degree of straining required differs widely by application, a broad selection of perforated metal screen sizes is offered, as well as screens utilizing fine wedge wire filtration. Contact our team of experts to learn more about the various types of strainers we have to offer and the different types of applications they can be used in like marine, military, data centers, HVAC, and more. 


Hellan Strainers are used in all industries that require the collection and removal of particulate from fluid systems.
