The AirTAC GFR30010F1T AirTAC Filter Regulator NPT3/8 | 300 Series 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 PT3/8" 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 GFR30010F1T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single compact body. This 300-size unit is configured with a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, and an embedded square pressure gauge scaled in MPa. The standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR line is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of thread (PT standard, G or NPT to order), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional) and gauge style and scale. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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 0.15 - 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 a control panel's valve manifold: the GFR30010F1T strips water and pipe scale from the plant air line and holds a steady regulated pressure to the directional valves, with the MPa gauge giving the operator a direct setting reference.
On a packaging or cartoning line, this filter regulator conditions the air going to cylinders and vacuum generators, keeping moisture out of the mechanism while the regulator holds the actuation pressure the machine cycle was set up for.
At a workshop drop or assembly bench, the unit cleans the shop supply and lets the operator dial in the working pressure for impact drivers, grinders and clamping fixtures, with the differential-pressure drain keeping the bowl clear during normal shifts.
Start with size and port: the 300 frame with a 3/8 in NPT port suits lines plumbed at that size, and larger frames carry larger ports and more flow. Choose the drain to match the installation: this unit's differential-pressure drain needs no attention during normal running, an automatic drain (code A) dumps condensate on a cycle, and a manual drain (code M) is emptied by hand. Pick the 40 um standard element for general plant air, or the 5 um element (code W) where finer particulate removal matters. The embedded square gauge here reads in MPa; psi or bar scales and an external round gauge are alternatives. Thread is NPT on this unit, with PT standard and G available as order options; a mounting bracket is included. Flow is published as curves, not a single rated figure, so send us your flow and pressure requirements 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 GFR flow as performance curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure, set pressure and expected air consumption, and we will confirm the relevant datasheet curve figures for this 300-size, 3/8 in NPT unit on request before you order.
This configuration has the differential-pressure drain: it discharges collected condensate automatically when the pressure drop across the 40 um element rises, so no manual draining is needed in normal service. If your application prefers a timed automatic drain or a simple manual drain bowl, those are catalogue options (codes A and M) you can order instead.
