The AirTAC GFR30010AJF2T AirTAC Filter Regulator NPT3/8 Auto Drain 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 GFR30010AJF2T is a size 300 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, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge reading in psi. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits -5 to 70 C (non-freezing) operation. No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, manual or automatic drain options, a 5 um (code W) element alternative, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. 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. |

| F | Gauge shape: Square. 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. |

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 clean, regulated air to the cylinder-driven taping heads on a packaging line's carton sealer, with the automatic drain handling condensate through long shifts.
Supplies regulated air to the pusher and diverter cylinders that move bottles between conveyor lanes, keeping actuator pressure steady as demand varies.
Regulates the air supply to pneumatic grippers and valves on laboratory automation benches, with the psi gauge giving operators a direct setpoint readout.
Choose the size by the port and flow your line needs: size 300 with a 3/8 in port sits mid-range, and larger sizes carry larger ports. Pick the drain: automatic (this unit, code A) suits unattended duty, manual suits periodic checks, and the differential-pressure default bleeds with pressure drop. The 40 um element is standard; specify 5 um (code W) where finer filtration matters. The gauge here is the embedded square type with a psi scale (code 2); MPa and bar scales are available. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as order options - this unit is NPT. Code J means no mounting bracket is fitted. Flow is published as curves, not a single rating, so 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 filter-regulator flow as curves rather than a single rated figure, so we do not quote a number here. Contact us with your flow demand and we will confirm the datasheet figures for this size 300, 3/8 in unit against your application.
This unit carries code A: the automatic drain ejects collected condensate on its own, which suits unattended or hard-to-reach installations. Manual-drain and differential-pressure-drain versions of the same size 300 body are also available in the GFR range.
