The AirTAC GFR30010JF2T AirTAC Filter Regulator NPT3/8, 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 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 GFR30010JF2T is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration has a 3/8 in NPT port, a 40 um filter element, a differential-pressure drain, a standard regulation range of 0.15-0.9 MPa (20-130 psi) and an embedded square gauge scaled in psi. Maximum working (inlet) pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), the bowl is polycarbonate, and no mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include manual or automatic drains, a 5 um element (code W), gauge scales in MPa, psi or bar, an external round gauge, a reverse/check valve, a mounting bracket, and G (BSPP) or NPT threads in place of the PT standard. 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.

Filtered, regulated air for the drawbar and clamping actuators on a CNC machining centre, keeping condensate and swarf-carried moisture out of the clamp cylinder while holding the set pressure.
Supply to diverters, pushers and sealing jaws on a packaging line, where the drain bowl strips condensate before it can reach the directional valves downstream.
Point-of-use conditioning ahead of spray guns and air-operated diaphragm pumps in a paint booth, holding a steady set pressure at the gun while the bowl catches water carryover.
Size steps from 200 to 600 as flow demand grows; this 300 size carries a 3/8 in NPT port. Drain type is a real choice: differential-pressure (this unit, no operator action), automatic, or manual. Filter grade is 40 um standard or 5 um with code W. The gauge is an embedded square unit with a scale of MPa, psi or bar (psi here), and an external round gauge is optional. Thread is PT as standard with G (BSPP) and NPT as order options, and brackets are optional. 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 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures on request.
This unit uses a differential-pressure drain, which bleeds condensate as air flows through and needs no operator action. A manual drain (code M) empties only when operated, and an automatic drain (code A) ejects condensate on its own - choose based on how often the line runs unattended.
