The AirTAC GFR30008F2 AirTAC Filter Regulator PT1/4, 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 PT1/4" 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 GFR30008F2 is a size-300 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1/4 in PT port, the standard 40 um filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi), and a mounting bracket is included.
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, optional 5 um (code W) filtration, automatic or manual drains, G or NPT threads, and alternate gauge scales. Flow is published as curves rather than a single rating, so we confirm datasheet and flow figures on request before you order.

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.

Feeds a clamping or light-press circuit on a production machine, supplying filtered air and holding the cylinder working pressure set on the psi gauge.
Installed ahead of packaging and cartoning machinery, cleaning condensed water and particles from the shop air while regulating the supply to actuators and sealers.
Mounted at a workshop air drop serving impact drivers and air ratchets, giving each station its own filtered, regulated supply at the pressure the tools need.
Size the GFR300 by port and flow: the 300 size with a 1/4 in PT port suits mid-range lines; step up to 400 or 600 for higher flow, or down to 200 for compact circuits. Choose the drain to match the duty: differential-pressure (this unit) drains with flow, automatic (code A) drains on a cycle, and manual (code M) needs an operator. If finer filtration is needed, the 5 um element (code W) is the option over the standard 40 um. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and the included bracket complete the selection. Flow for this family 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 GFR performance as flow curves rather than a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow and datasheet figures for this 1/4 in, size-300 unit on request before you order.
This unit has the standard differential-pressure drain, which expels collected condensate automatically as air flows through the bowl. If your line runs intermittently at low flow, an automatic drain (code A) or a manual drain (code M) may suit better - both are orderable options on this family.
