The AirTAC GFR30010AJC2WT AirTAC Filter Regulator NPT3/8, 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 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 GFR30010AJC2WT is a GFR300-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/8 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that expels collected condensate without manual attention, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round pressure gauge reading in psi. It is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl is standard at this size.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and gauge or no-gauge variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

|---|---|
| 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). |
| C | Gauge shape: Round. 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.

Point-of-use air preparation for a pneumatic press or clamp cylinder: the 5 um element protects the valve and cylinder from water and particles while the regulator holds a steady working pressure at the machine.
Filtered, regulated air for diverters, lifters and stop gates on a packaging conveyor, with the automatic drain keeping condensate off the bowl in an area nobody inspects between shifts.
Clean, stable supply air for sample-handling grippers and small actuated valves on laboratory automation, where the 5 um grade and a psi gauge support repeatable, instrumented setups.
Size 300 with a 3/8 in NPT port sits in the middle of the GFR range; step up to size 400 or 600, or down to 200, according to the flow your line needs - we will check the published flow curves against your demand if you send the figures. The 5 um element in this code is the finer catalogue grade; choose 40 um (standard) where only coarse water and particle removal is needed. The automatic drain suits unattended duty; manual drain is the low-cost choice where someone checks the bowl routinely, and differential-pressure drain is the catalogue default. The round psi gauge in this code is the external gauge option; an embedded square gauge with MPa, psi or bar scale is also available. PT is the standard thread; G and NPT are order options. A bracket is optional (this code is supplied without one). Because flow is published as curves and not a single rating, 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, not as a single rated number, so we do not quote a figure here. Send us your line pressure and required downstream flow and we will confirm the datasheet curve figures for this exact model on request.
The A in the code selects the automatic drain, which ejects collected condensate without manual intervention - useful on unattended or hard-to-reach installations. The W selects the 5 um element, the finer of the two catalogue grades (40 um is standard). Both are decodable choices, and the manual-drain variant carries a wider 0.05-0.9 MPa adjustment range if you ever prefer it.
