¡¤ Compact in-line design
¡¤ Replaceable filter element
¡¤ Particle trapping for clean fluid

The filter element, which is made of sintered stainless steel, is porous and has lots of tiny holes. The particles bigger than holes are not allowed to pass through, hence clean fluid. After certain period, the holes may be blocked by particles and pressure drop will increase. This depends upon the total flow through elements and cleanliness of upstream flow. The element needs be replaced for clean fluid with minimum pressure drop.

¡¤ Maximum Operating Pressure : 3000 psig @ 70¢µ (21¡É)
¡¤ Operating Temperature : -15¢µ to 400¢µ (-26¡É to 204¡É)
¡¤ Effective Filtration Area :
