LIQUID FILTER & STRAINER
25 Series (In-line) / 24 Series (90 Angle)

APPLICATION
Stainless steel filters and strainers are used in liquid flow systems for removal of various size particles.

WORKING PRINCIPLE
Filters allow the removal of fine particles from various liquids. The stainless steel mesh can be reused after cleaning. Strainers are coarse filters that remove larger particles.

STANDARD DESIGN
The filters and strainers consist of a housing with an inlet and outlet. Inside the housing the straining element is fixed in such a way that the flow is forced through it. This element consists of a backup tube and straining mesh which is fitted between two flanges by means of a rubber gasket. The flanges clamp to the housing with a standard clamp and gasket, allowing for easy assembly and disassembly for cleaning or inspection. All seats and seals are made from FDA approved materials.

PROPER FILTERING RECOMMENDATIONS
These filters and strainers are designed for particulate removal in liquid flow systems. They are not made to remove product impurities or odors. Effectiveness of the filter and strainers vary according to line pressure, size and amount of particles in a product, etc.

FILTER MEDIA SHOULD BE CHANGED IF THERE IS A PRESSURE DROP OF 2 TO 5 PSI OVER NORMAL PRESSURE.
When using strainers or filters with a high speed or positive displacement pump, use a by-pass or pressure relief system to protect the strainers and filters.
