The Parker Racor FBO-10-DP assembly features an aluminum die-cast filter head with four hand operated bolts and a locking ring collar. The filter housing rotates into the locking ring collar, and is simple and easy to remove without undue mess or difficulty by a single technician. The slotted locking ring collar allows maintenance personnel to hand-loosen the four collar bolts, rotate and lower the bowl assembly for element change outs. With a new element installed, simply raise the bowl, rotate into position on the locking ring, then hand tighten evenly. The closure hardware consists of stainless steel nuts, bolts and washers with metal hand knobs for ease of maintenance. This unit features a Differential Pressure Gauge.
