The AirTAC GFR30010MF2WTK 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 GFR30010MF2WTK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, with a 3/8 in NPT port. Water and particulate are removed by a 5 um filter element (the fine grade of the two offered - 40 um is the standard alternative), and the downstream pressure is set with the standard regulator over a 0.05-0.9 MPa (7-130 psi) adjustment range. The bowl is manual-drain polycarbonate, so condensed water is emptied by hand as part of routine maintenance. This configuration carries an embedded square gauge scaled in psi, a reverse (check) valve to hold the regulated setting when upstream supply is lost, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, and options across drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options) and bracket choice. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the flow and datasheet 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.

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.

On a workholding clamping circuit, this unit filters the shop air to 5 um and holds a set clamping pressure on the downstream side, with the check valve helping the setting survive a brief upstream drop. The psi gauge lets the setter read the clamp pressure directly.
Feeding a packaging machine's directional-valve manifold, the 5 um element keeps fine particulate out of the valve spools while the regulator holds the supply pressure the valve manufacturer specifies. The manual-drain bowl is emptied during the shift-end walkaround.
Mounted on the panel at the inlet of a robot cell's air preparation manifold, this 3/8 in unit combines filtration and regulation in one body to save panel space, with the included bracket fixing it to the backplate and the square psi gauge giving operators a visible setpoint.
Size and port: the GFR300 steps up from the 200 series with a larger body and a 3/8 in port, so choose it when the line's flow demand sits above what a 1/4 in unit carries comfortably - match the size step to the flow your circuit needs. Drain: this unit is manual-drain, which suits installations where someone walks the line and can empty bowls on a schedule; if the unit sits in an inaccessible spot, the automatic or differential-pressure drain variants are the better decode. Filter grade: the 5 um element here is the finer choice for downstream valves, cylinders and instruments that tolerate less particulate than the 40 um standard grade. Gauge: the embedded square gauge is fitted and scaled in psi; external round gauges and MPa or bar scales are available. Thread: this code is NPT; PT is the catalogue standard and G (BSPP) is also an order option. A mounting bracket is included, and the reverse (check) valve is fitted.
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Tell us your application and we will confirm sizing against the datasheet on request.
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 family as curves rather than a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the flow figures from the datasheet for this exact 3/8 in configuration on request.
The M in the code specifies a manual-drain polycarbonate bowl: condensed water is emptied by hand during maintenance rounds. It is a good fit where the unit is accessible and checked regularly. If the unit will be hard to reach, the same series is available with automatic or differential-pressure drains - ask us and we will decode the right variant for your installation.
