The AirTAC GFR30010AJF2WT AirTAC Filter Regulator NPT3/8 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 PT3/8" ports, a automatic 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 GFR30010AJF2WT is a size-300 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/8 in NPT port, a 5 um filter element (code W, finer than the standard 40 um), an automatic drain that purges collected condensate without manual attention, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and an embedded square gauge scaled in psi. The polycarbonate bowl suits the 300 size, and no mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, and choices of drain type, filter grade, gauge scale and thread (PT standard, G and NPT as order options). 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic 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. |
| T | NPT 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.

Clean, regulated air feeding the cylinders of a bench-mounted pneumatic press, with the 5 um element protecting the directional valve and the psi gauge giving the operator a direct setting reference.
Air preparation for the divert and clamp cylinders on a packaging conveyor line, where the automatic drain keeps condensate out of the circuit during continuous shifts without operator attention.
Point-of-use conditioning for a laboratory automation skid, where the finer 5 um filtration and stable regulated pressure protect sensitive pneumatic metering and sampling components.
Size 300 with a 3/8 in port suits lines whose air demand sits between the smaller 200/1/4 in and larger 400/1/2 in steps; match the size to the flow your circuit needs and we will confirm it against the published curves before you order. The 5 um element (W) is the right choice when downstream valves or instruments tolerate less particulate than the standard 40 um grade. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are available on other codes. The square gauge here reads in psi; MPa and bar scales exist on other variants. Thread is NPT on this code, with PT standard and G available to order, and this unit ships without a mounting bracket.
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 this series as curves, not as a single rated number, so there is no one figure we can quote. Send us your line pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
The code decodes them directly: A is the automatic drain, which purges collected condensate on its own instead of relying on manual or differential-pressure operation, and W selects the optional 5 um filter element in place of the standard 40 um grade. Both are standard catalogue choices for the GFR family.
