Purolator industrial coalescer cartridges provide efficient and economical filtration and coalescence of fluids in a wide range of applications where API certification is not required. This broad range of liquid/liquid coalescers provides greater coalescing efficiency and contaminant holding capacity than most conventional coalescers or other separation techniques. As a result, Purolator industrial coalescers improve product quality, reduce maintenance costs and help prevent unscheduled shutdowns.
