The AirTAC GFR30010ALC2 AirTAC Filter Regulator PT3/8 Low-Pressure 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 GFR30010ALC2 is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with 3/8 in PT ports, an automatic drain that expels collected condensate without operator attention, the standard 40 um filter element, and the low-pressure regulator type (code L) for circuits that run below standard supply pressures. A round gauge reading in psi is fitted, a mounting bracket is included, and the polycarbonate bowl carries a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, gauge and scale options, and G or NPT thread variants to order. Flow is published as curves rather than a single rated figure, so contact us and we will confirm the datasheet figures 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.

Conditioning and regulating air to the fill-head and capper cylinders on a beverage bottling line, with the automatic drain clearing condensate through humid production shifts.
Feeding gripper circuits on an assembly robot where pressure must sit at a stable low setting and the fitted psi gauge gives operators a local readout.
Point-of-use treatment ahead of loom jet and cylinder circuits, filtering line water and particulate before it reaches the machine's pneumatic valves.
Size steps from 200 through 600, so match the GFR300's 3/8 in PT port to your line size and expected demand. Drain choice is a real decision: automatic (this unit, code A) empties the bowl on its own, manual (M) needs operator attention, and differential-pressure (blank) bleeds when the pressure drop warrants. Filtration is 40 um as coded; specify W for a 5 um element. The round gauge here reads psi; the embedded square gauge and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included. 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 flow for the GFR300 as curves rather than a single rated figure, so we do not quote a number here. Send us your line size and air demand and we will confirm the datasheet flow figures for this exact model on request.
Code A fits the automatic drain, which expels collected condensate without operator attention - useful on unmanned cells or humid sites. Manual (M) and differential-pressure (blank) drains are catalogue alternatives on the GFR300 if you prefer hands-on control or bleed-on-demand behaviour.
