The AirTAC GFR40010AJC2T AirTAC Filter Regulator NPT 3/8 in 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 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 GFR40010AJC2T is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/8 in NPT port, an automatic drain that expels collected condensate without manual attention, the standard 40 um filter element, and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with automatic drain, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing), and the polycarbonate bowl suits the 400 size.
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, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, gauge style and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow 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.

| 10 | Port size PT3/8". This body offers 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 conditioning and pressure setting for the clean, regulated air feed that actuates a CNC machine's tool-change cylinders, clamps and pneumatic gates.
Feeding filtered, regulated air to the stopper cylinders, diverters and pushers on a bottling or carton packaging conveyor, with automatic drain handling condensate between shifts.
Conditioning shop air ahead of spray guns and air-assisted applicators in a finishing booth, where water and particulate removal plus a stable set pressure protect finish quality.
Size and port are the first decodable choice: the GFR400 step with its 3/8 in NPT port suits lines with higher air demand than the 200/300 sizes, but the right step depends on required flow, and flow is published as curves rather than a single rating - ask us to confirm sizing against your application before ordering. Drain type matters in practice: automatic drain (this model) suits unattended or hard-to-reach installations, manual drain suits attended points, and the differential-pressure default drains on pressure drop. Filter grade is 40 um standard; specify W for 5 um where finer particulate removal is needed. Gauge options are the embedded square gauge or an external round gauge in MPa, psi or bar scales (this model: round, psi). Thread is PT as standard with G and NPT as orderable options; brackets are optional (this model: no 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 the GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow and datasheet figures for this 3/8 in, size-400 unit on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the bowl without manual attention - useful for unattended or hard-to-reach installations. The GFR family is also available with manual drain (code M) or the differential-pressure default, which drains on pressure drop. Note that with automatic or differential-pressure drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
