The AirTAC GFR30008F2T AirTAC Filter Regulator NPT1/4, psi Gauge is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR30008F2T is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the 300 size with a 1/4 in NPT port, a 40 um standard filtration element, a differential-pressure drain in the PC bowl, and the embedded square gauge fitted with a psi scale. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit carries a mounting bracket.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port options from 1/8 to 1 in, thread choices of PT, G and NPT, manual or automatic drain options, a 5 um element (code W), and gauge scale choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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 0.15 - 0.9 MPa (20 - 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.

Feeding clean, regulated air to tool-clamp and chip-clearing circuits on a CNC cell, with the psi gauge giving operators a local setpoint readout at the machine.
Conditioning the supply to carton-forming and sealing cylinders on a packaging line, where the 40 um element protects valve spools and the regulator holds a steady working pressure.
Prepping air for gripper and vacuum-generator circuits on a robot cell, keeping moisture and debris out of the E-valve manifold while setting the pressure the grippers need.
Start with the port and size step: the 300 size with a 1/4 in NPT port suits typical machine-supply lines, while stepping up to 400 or 600 gives larger ports where the downstream demand is bigger. Decide the drain: this unit uses the differential-pressure drain (default); automatic (A) or manual (M) drains are orderable where the installation needs them. The 40 um element is standard; specify the 5 um W grade if finer particulate removal matters. The fitted square gauge here reads in psi; MPa or bar scales are available, and an external round gauge is an option. PT is the standard thread, with G and NPT as orderable options, and a bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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 as curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Send us your line pressure and downstream demand and we will confirm the flow data from the datasheet for this exact model before you order.
The F2 in the code specifies the embedded square gauge with a psi scale (MPa and bar scales are alternatives), and the trailing T specifies the NPT thread on the 1/4 in port. PT is the catalogue standard thread, with G and NPT as orderable options, so this unit is configured for a US-style NPT installation.
