The AirTAC GFR30008JF2W AirTAC Filter Regulator PT1/4 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR30008JF2W is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, sized for a PT1/4 (1/4 in) port. The W code selects the 5 um filter element (finer than the 40 um standard) for removing water and particulate, and the blank drain position gives the differential-pressure drain as the default. The F2 code fits the embedded square gauge with a psi scale, and the J code means no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), the polycarbonate bowl suits -5 to 70 C non-freezing service, and no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with a choice of ports, thread types (PT standard, G and NPT as order options), drain types, filter grades and gauge scales. Flow is published as curves rather than a single rated figure, so we 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.

|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 filtered, pressure-regulated air to the clamp and fixture cylinders on a CNC machining cell, where the 5 um element helps keep water and fine particulate out of the clamping valves.
Conditions the supply ahead of spray guns and air-assist lines in a finishing booth, combining water/particulate removal and a set working pressure in one PT1/4 unit.
Supplies regulated air to the stopper, diverter and pusher cylinders along a packaging conveyor, with the psi-scaled square gauge giving operators a direct pressure readout at the machine.
Choose the GFR300 size and PT1/4 port against the air consumption of the downstream circuit, stepping up to size 400 or 600 where the line demands more flow - we confirm exact sizing from the published flow curves before you order. This unit is already configured with the 5 um element, the differential-pressure drain, the square gauge on a psi scale and no bracket; the 40 um element, automatic or manual drain, MPa or bar gauge scales, an external round gauge, a bracket, G or NPT thread and a reverse/check valve are the alternative decodable options in the range. If your application needs finer filtration than 5 um or a lubricator downstream, route that to us to confirm the right combination.
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 there is no one rated flow number we can honestly quote. Tell us your operating pressure and the air consumption of the equipment downstream, and we will confirm the sizing from the datasheet curves on request before you order.
In the code GFR30008JF2W, the W selects the 5 um filter element instead of the 40 um standard, and F2 fits the embedded square gauge with a psi scale. The differential-pressure drain (blank position) and PT thread are the defaults. If you need the 40 um element, an automatic or manual drain, an MPa or bar gauge scale, a G or NPT thread or a mounting bracket, those are available as different decodable codes in the same series - ask us to quote the exact variant.
