The AirTAC GFR30010ALC2K AirTAC Filter Regulator 3/8 in PT 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 GFR30010ALC2K is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air at the standard 40 um grade and regulates downstream pressure as a low-pressure type. This configuration is built with a 3/8 in PT port, an automatic drain that expels collected condensate without manual attention, a round pressure gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. The polycarbonate bowl lets you see the condensate level at a glance, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drains, an optional 5 um filter grade (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads as order options alongside the PT standard. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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. 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.

| 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. |

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 the cylinders and actuators on a carton-forming or wrapping line, with the automatic drain keeping condensate out of the supply during continuous shifts.
Supplies clean, pressure-controlled air to the pop-up gates, stops and diverters along a conveyor system, where the low-pressure regulation suits gentle-actuation circuits.
Prepares the air feeding benchtop laboratory automation and sample-handling equipment, with the 40 um filter and psi gauge giving a visible, controlled supply at the point of use.
Start with the port step: this unit is the 300 size with a 3/8 in PT port; smaller and larger sizes (200 to 600, 1/8 in to 1 in) exist if your line needs a different connection or capacity. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your actual air demand before ordering. The automatic drain on this unit suits unattended duty; a manual drain (code M) or the differential-pressure default are alternatives if you prefer. The standard 40 um grade covers general air preparation; specify the W code for the 5 um grade if finer filtration is needed. The round psi gauge fitted here is the external style; an embedded square gauge with MPa, psi or bar scales is also available. PT is the standard thread on this model, with G (BSPP) and NPT offered as catalogue options to order, and the bracket is included.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow 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 one number. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for this exact model on request before you order.
The A in the code sets the automatic drain, which expels collected condensate by itself instead of waiting for a manual bleed - useful on equipment that runs unattended. The K sets a reverse/check valve, and the C2 sets the round gauge reading in psi. The L marks the low-pressure regulator type, whose exact adjustment range we confirm from the datasheet on request.
