The AirTAC GFR30010F2G AirTAC Filter Regulator G3/8, 40 um, 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 GFR30010F2G is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 300-size unit carries a G3/8 (BSPP) port, a 40 um standard filter element, a differential-pressure drain and an embedded square gauge reading in psi. Its regulation range is 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and it operates from -5 to 70 C (non-freezing). The polycarbonate bowl keeps collected condensate and debris visible, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR300 series is one of four sizes (200, 300, 400, 600) with ports from 1/8 to 1 inch, PT as standard and G or NPT as order options; drains come as differential-pressure, automatic or manual, and a 5 um element (code W) can be ordered in place of the 40 um standard. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure 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 filtered, regulated air to the clamping fixtures and tool-change cylinders of a CNC machining center, where chips and condensate in the shop-air line must be stripped out before they reach the valves.
Conditioning the air supply to the pusher and sealing cylinders on a carton-sealing conveyor, holding a steady set pressure so stroke timing stays repeatable through the shift.
Point-of-use regulation at assembly-station air drops in a plant, so each station sets its own downstream pressure independently of fluctuations in the main header.
Match the size and port to the air your application actually consumes: this 300-size unit has a 3/8 inch port, and the larger sizes move more flow. This code pairs the 40 um standard element with a differential-pressure drain, which bleeds off collected condensate as the pressure drop across the element builds; an automatic or manual drain can be ordered instead. The embedded square gauge reads in psi, with MPa or bar scales available and an external round gauge as an option. The thread here is G (BSPP); PT is the standard and NPT can be ordered. Flow is published as curves, not a single rating, so 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 series as curves rather than a single rated figure, so we do not quote one number. Send us your air consumption and line pressure and we will confirm from the datasheet whether this 3/8 inch unit is correctly sized for your application.
F means the embedded square gauge is fitted, and 2 sets its scale to psi. MPa or bar scales are available, and an external round gauge can be ordered instead of the square gauge.
