The AirTAC GFR30010ALC2T AirTAC Filter Regulator 3/8 in NPT 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 GFR30010ALC2T is a 300-size 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, the standard 40 um filter element, an automatic drain that ejects collected condensate without manual attention, and the low-pressure regulator type. It is fitted with an external round pressure gauge reading in psi, includes a mounting bracket, and carries a polycarbonate bowl. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, plus options for drain type, 5 um filtration (code W), thread style and gauge scale. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

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, regulated air to clamp cylinders on a CNC fixture line, where the low-pressure regulator type holds a moderate clamping pressure and the automatic drain keeps condensate out of the valves between shifts.
Sits at the drop point of a packaging conveyor to clean and regulate air for diverters and pusher cylinders, with the psi gauge giving operators a visible setpoint at the machine.
Prepares air for pick-and-place grippers at a bench assembly station: the 40 um element protects the gripper valve, the bracket mounts the unit to the station frame, and the round gauge confirms supply pressure at a glance.
Start with the port step: this unit is the 300 size with a 3/8 in NPT port; smaller 200 and larger 400/600 sizes exist if your line needs a different connection or flow path. Choose the drain to match access: automatic (this unit, code A) suits enclosed or infrequently attended installations, while manual and differential-pressure drains are the other catalogue choices. The standard element is 40 um; specify 5 um (code W) where finer particulate removal matters. Gauge scale is selectable (MPa, psi or bar) and this unit carries the external round gauge in psi. Thread is NPT here; PT (standard) and G are the other order options. A mounting bracket is included.
Flow for this series is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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 rather than a single rated figure, so we do not quote one number. Tell us your application and required flow and we will confirm the sizing against the datasheet on request.
The A in the code specifies an automatic drain, which expels collected condensate from the bowl without operator attention - useful where the unit is mounted in a hard-to-reach spot. The catalogue also offers manual drains and a differential-pressure drain as the default option, so you can order the style that matches your maintenance routine.
