Housing pressure drop is 0.6 PSID at 7 GPM (40mbar @ 26.5 lpm)
Graver High Flow Series filters feature a larger geometry to handle higher flows with fewer filter elements. The result is much faster, easier filter changeouts.
Key features:
6″ diameter, large geometry for high flow rates
Absolute retention ratings from 1 to 100 microns
Capable of flow rates up to 500 GPM in a single 60″ element
Inside-out flow retains contaminant even during changeout
Multi layer pleated construction with optimized surface area
Outer cage prevents media extrusion problem experienced with some competitive offerings
Unique Quad Seal gasket provides maximum seal integrity
Graver High Flow RF Series filter housings are designed to accept Graver’s and competitive High Flow RF Series large geometry filter elements. Available in both vertical and horizontal orientations, the High Flow RF housings are available in designs to accommodate from 1 to 15 filter elements, from 10″ to 60″ long. Constructed of 304 or 319 stainless steel, standard design is rated for 150 PSIG (10.3 bar) with higher pressure design available upon request.
Key features:
Industrial grade housings available in 304L and 316L Stainless Steel wetted parts
Designs for 1, 3, 4, 7, 10, 12, 15, filters per housing
Single Round -Segment Screw hold down clamps; Multi-round -swing bolt hold down clamps
150 psig design
Accepts 10″, 20″, 40″ and 60″ High Flow RF cartridges
