The AirTAC GFR30008JF2 AirTAC Filter Regulator PT1/4 Square 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 GFR30008JF2 is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single compact body, so one 1/4 in PT unit does both jobs ahead of valves, cylinders and tools. This configuration carries the 40 um standard filter element with a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a square pressure gauge reading in psi for direct setting of the 0.15-0.9 MPa (20-130 psi) regulation range. The bowl on this 300-size unit is polycarbonate, and no mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um element option, alternative gauge scales, and G (BSPP) or NPT threads to order. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Mounted ahead of the solenoid valves and clamping cylinders on a CNC machining centre, it cleans the shop air and holds a steady set pressure so workholding and tool-change actuation behave consistently through the shift.
On a bottling or canning conveyor, it conditions the air feeding stopper and gate cylinders, keeping water carryover out of the valves while the gauge lets the line technician read and hold the setting in psi.
At a packaging line carton-sealing station, it filters and regulates the air feeding the flap-fold and taping heads, with the differential-pressure drain handling condensate so the station can run unattended between checks.
Start with the port: this unit is 1/4 in PT, one step up from the 200 size, and the 300 frame suits lines running moderate air demand - step to 400 or 600 if your circuit grows. Choose the drain to match access: the differential-pressure drain here works unattended, the automatic option (code A) cycles on pressure, and manual (code M) suits monitored points. The 40 um element is standard; specify the 5 um W option where finer protection is needed. The square gauge here reads psi; MPa and bar scales are alternatives, and an external round gauge is optional. PT is the standard thread, with G (BSPP) and NPT available as order options, and brackets can be added where this bracketless version is panel- or body-mounted instead.
Flow for the GFR series is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet 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 flow for the GFR series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote honestly. Tell us your inlet pressure and the demand of the equipment downstream, and we will confirm the sizing against the datasheet before you order.
The blank drain code on this model means the differential-pressure drain: condensate collected in the polycarbonate bowl is discharged automatically as air flows through, with no operator action. If your line has low or intermittent flow, the automatic (A) or manual (M) drain versions of the same GFR300 1/4 in unit may suit better - ask us for those codes.
