The AirTAC GFR30010MF3WT AirTAC Filter Regulator NPT3/8 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 GFR30010MF3WT 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 threaded NPT3/8 (3/8 in), carries a fine 5 um filter element, drains condensate by hand via the manual drain, and is fitted with an embedded square gauge scaled in bar. The polycarbonate bowl lets you see the condensate level at a glance, and the standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options including automatic or differential-pressure drains, a 40 um standard element, alternative gauge scales (MPa/psi/bar), G or NPT threads, and a reverse/check valve. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow figures for your application on request.

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.

| F | Gauge shape: Square. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Feeding clean, regulated air to tool clamps and pneumatic actuators on a CNC machining centre, where the 5 um element protects fine spools and the bar gauge keeps set pressure visible at the machine.
Supplying filtered, regulated air to the actuated fill and capping valves on a bottling line, with the manual drain emptied during scheduled changeover stops.
Regulating air to diverter and stopper cylinders on a packaging conveyor, where the single filter-regulator body saves panel space and the bracket gives a clean mounting point.
Start with the size and port: the 300 frame with its 3/8 in NPT port suits lines whose air demand sits between the smaller 200/1/4 in step and the larger 400/1/2 in step - match the port step to the pipe and the flow curve to your consumption. This unit is already configured with the fine 5 um element (choose 40 um where only coarse protection is needed) and a manual drain (choose automatic or differential-pressure drain where the unit is hard to reach or the duty is wet). The square gauge is scaled in bar; MPa and psi scales and an external round gauge are alternatives. PT is the standard thread and G or NPT are order options - this unit is the NPT version. A mounting bracket is included.
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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number here. Tell us your line pressure, set pressure and air consumption and we will confirm the flow and the full datasheet for this exact model on request before you order.
The M in the code specifies a manual drain: condensate collects in the polycarbonate bowl and is released by hand, which suits accessible mounting points with scheduled maintenance. If the unit will be hard to reach or the air is wet, ask about the automatic or differential-pressure drain variants of the same GFR300 filter regulator.
