The AirTAC GFR30010JF2 AirTAC Filter Regulator 3/8 in PT, Square 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 GFR30010JF2 is a size-300 filter regulator that cleans compressed air and holds downstream pressure in one body. Water and particulate are removed by the 40 um filter element, while the standard regulator holds your set pressure between 0.15 and 0.9 MPa (20-130 psi). This configuration has PT3/8 ports (PT is the standard thread; G and NPT are order options), a differential-pressure drain that bleeds condensate automatically as flow passes through, a polycarbonate bowl suited to the 300 size, an embedded square gauge reading in psi, and no mounting bracket. 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 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, and options that include automatic or manual drains, a 5 um filter element (code W), alternative gauge scales, G or NPT threads, and a mounting bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 bench-mounted pneumatic press or clamping fixture, where the regulator holds a repeatable set pressure for consistent forming or holding force and the 40 um element keeps water and scale out of the cylinder valves.
Point-of-use preparation on a cartoning or wrapping line, where actuators and air cylinders need clean, regulated air at a stable pressure and the differential-pressure drain keeps condensate moving out without operator visits.
Installed on individual drop legs along an assembly line, giving each workstation its own filtered and regulated air supply at the set pressure, with the psi square gauge letting operators verify the setting at a glance.
Size and port step up with required flow: 200, 300, 400 and 600 cover ports from 1/8 to 1 inch, so pick the size whose flow curve clears your demand with margin. This unit is the 300 size with PT3/8 ports. Drain choice matters: differential-pressure drain (this unit) needs no attention while air is flowing, automatic drain empties the bowl on its own, and manual drain suits installations you visit regularly. Filter grade is 40 um as standard here; specify code W for 5 um where finer protection is needed. The embedded square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard with G and NPT as order options, and a bracket can be added if this no-bracket version does not suit your panel.
One honest note before you order: flow for the GFR series is published as curves, not a single rating, so we cannot quote a rated flow number here. Send us your application details and we will confirm the datasheet and sizing before you commit.
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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your application details and we will confirm the datasheet and check the sizing against your required flow on request.
This unit has a differential-pressure drain, which discharges condensate automatically as air flows through the bowl, with no operator action needed while the line is running. If your line has long idle periods, an automatic drain (code A) empties the bowl on its own; a manual drain (code M) suits installations that are visited regularly. All three drain types share the same 0.15-0.9 MPa (20-130 psi) regulation range on this standard regulator.
