Filter Regulator Lubricator

Marsh Bellofram Filter-Regulator-Lubricators (FRLs) are designed with economy and convenience in mind. Filter Regulators have the same features as the regulators with the addition of polycarbonate bowls, 5 or 50 micron filters, and with manual, semi-automatic or automatic drains. Lubricators feature polycarbonate bowls, with field-settable dials providing variable lubrication between 0 and 90 drips per minute.
