Filter, Regulator, Lubricator


Marsh Bellofram filter, regulator, lubricators (FRLs) are pre-packaged, fully configurable modular assemblies of popular configurations of air filters, regulators, lubricators, and gauges, offered as a single unit. Designed with economy and convenience in mind, Marsh Bellofram FRLs are available in miniature and standard. Regulators incorporate patented Bellofram rolling diaphragms, which have become the industry gold standard for quality and performance, with metal body, polycarbonate bonnet, a non-rising adjustment knob, and panel, pipe, or bracket mounting capabilities.

Filter regulators offer the same features as the pressure regulators with the addition of polycarbonate bowls, 5 or 50 micron filters, and manual, semi-automatic, or automatic drains. Lubricators feature polycarbonate bowls and field settable dials providing variable lubrication between 0 and 90 drips per minute. Units are available in 0-30, 0-60, and 0-120 psi output pressure ranges with a maximum supply pressure of 120 psi. FRLs are also offered with choice of 3/8, 1/2, 3/4, and 1 NPT pipe sizes. Their modular design facilitates easy maintenance and swap-out of the filter, regulator, or lubricator.
