The AirTAC GFR30010MF2WK AirTAC Filter Regulator PT3/8 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR30010MF2WK is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is a PT3/8 (3/8 in) unit with a 5 um filter element for finer filtration than the standard 40 um grade, a manual drain on the polycarbonate bowl, an embedded square gauge reading in psi, a built-in reverse/check valve, and the mounting bracket included. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR filter-regulator line, available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, and a choice of drain type, filter grade, gauge style and scale. Flow data for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeds filtered, regulated air to the pneumatic clamps, tool-change actuators and purge lines on a machining centre, with the 5 um element protecting fine spool valves from particulate carryover.
Sits at the drop point on a carton-forming or wrapping line, conditioning the air that drives the sealing and pusher cylinders and holding a steady set pressure as line demand fluctuates.
Installed at a branch take-off on the factory air ring main, giving a work cell its own locally regulated supply, with the check valve holding the downstream circuit if the main is depressurised.
Pick the size and port against the air demand of the circuit: this 300-size unit carries PT3/8 (3/8 in) ports, and the GFR line steps up through 400 and 600 for larger flows. On filtration, the standard element is 40 um; this model carries the 5 um (code W) element, so choose it where downstream valves, cylinders or instruments need finer air. Drain choice matters: manual drain (this unit) needs an operator to bleed the bowl, while automatic and differential-pressure drains discharge condensate on their own. The embedded square gauge reads in psi here; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and a reverse/check valve is fitted on this unit. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet curves on request.
The M in the code selects the manual drain on the polycarbonate bowl: condensate collects in the bowl until an operator opens the drain to bleed it off. If you would rather not rely on manual bleeding, the GFR300 series is also available with automatic or differential-pressure drains - just ask for the equivalent code.
