The AirTAC GFR30010JC2T 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 AirTAC GFR30010JC2T is a 300-size filter regulator that cleans compressed air and holds downstream pressure in one body. Water and particulate are removed by the 40 um standard filter element, while the integrated standard-type regulator holds your set pressure across a 0.15-0.9 MPa (20-130 psi) adjustment range. This configuration has 3/8 in NPT ports, a differential-pressure drain that bleeds condensate automatically as flow passes through, and a round external gauge scaled in psi so operators can read and set pressure directly. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl gives a clear view of condensate level.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and can be ordered with manual or automatic drains, a 5 um (W) filter element, different gauge scales, G or NPT threads in place of the PT standard, and with or without a mounting bracket. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the 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 0.15 - 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.

Installed ahead of an air-operated press or clamp cylinder circuit, it removes pipe-scale and condensed water from the shop air and holds a steady regulated pressure so cycle force stays repeatable shift after shift.
Mounted at the air inlet of a carton-sealing or wrapping machine, it protects the machine's directional valves from water and debris while the psi gauge lets maintenance set the line pressure the machine was designed for.
Fitted at a workbench drop feeding air tools and small actuators, it gives each operator a locally filtered and regulated supply, with the round psi gauge readable at a glance and the differential drain keeping the bowl clear during normal use.
Start with the port and size step: this unit is size 300 with 3/8 in NPT ports, one step up from 1/4 in; if your line may grow, moving to size 400 (1/2 in) gives more flow capacity, but confirm sizing against the published flow curves before ordering. For the drain, differential-pressure (this unit) needs no attention during normal flow, automatic (code A) suits intermittent low-flow duty, and manual (code M) gives operator-controlled draining. The 40 um element is standard; choose the 5 um W grade where downstream valves or instruments need finer filtration. Gauge choices are the embedded square gauge or the external round gauge fitted here, in MPa, psi or bar scales. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. Brackets are optional (code J omits the bracket).
Flow is published as curves, not a single rated figure, so send us your application details and we will confirm the datasheet figures 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 performance as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure and the flow your application needs, and we will confirm the datasheet curve figures for the GFR300 on request before you order.
The differential-pressure drain (the default, no code letter) bleeds condensate from the bowl automatically as air flows through, so it suits lines with continuous use. Choose code A for an automatic drain on intermittently used lines where flow may be too low to trigger the differential drain, or code M for a manual drain where an operator drains the bowl on a schedule.
