Angle type strainers

AWH strainers are intended for use in pipelines, for coarse cleaning and filtration of liquid flows for the food, chemical and pharmaceutical industry as well as for low-germ processes. They are suitable for use in processing low-viscosity flowing media like water, steam, liquid foods and drinks with high hygienic requirements.

Dirt trap

AWH dirt traps protect the product and the process system, pumps and heat exchangers against damage from foreign bodies. Our dirt traps are Y-shaped (Y filter). The direction of flow is always from the inside to the outside. The trap should be installed so that the filter insert is removed from below. Its streamlined shape ensures reliable processes in a simple and cost-effective way. We offer gap filters with gap widths of 1 mm, 0.5 mm and 0.25 mm. Compared to conventional perforated sheets, slotted tubes offer much greater flexibility and a far larger free strainer surface.

Solids filter

The AWH has developed a filter for highly abrasive media that retains unwanted particles in powdered media. The filter can be used anywhere where contamination with foreign particles can occur. For example, changing media in tank trucks ensure that residues from the previous medium have to be filtered out. In addition, coarse-grained contaminants can be removed from powdery media.
