The AirTAC GFR30010LC2TK AirTAC Filter Regulator, NPT3/8, 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 differential-pressure 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 GFR30010LC2TK is a size 300 GFR-series 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 NPT ports, the low-pressure regulator type, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically as flow passes through. It ships as coded with an external round gauge on a psi scale, a reverse/check valve fitted, and a mounting bracket included. The polycarbonate bowl is rated for the family's 1.0 MPa (145 psi) maximum inlet pressure and -5 to 70 C (non-freezing) operation.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and each size can be ordered with manual or automatic drain, a 5 um (code W) element, square or round gauges on MPa, psi or bar scales, G or NPT threads, and bracket options. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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.

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.

Mounted at the drop of a cartoning or wrapping line, this unit filters carryover water and scale from the shop air and holds a steady, reduced supply pressure to the machine's cylinder and vacuum circuits, with the psi gauge giving operators a direct reading at the panel.
On a machining fixture that clamps with air cylinders, the filter element keeps grit out of the clamp valves while the regulator holds the clamping pressure the process calls for, and the fitted check valve holds the downstream circuit against supply-side pressure loss.
Where an assembly cell runs air actuation at reduced supply pressure, the low-pressure regulator type is the right control choice; the 3/8 in NPT ports tie into the cell manifold, and the differential-pressure drain keeps condensate out of the downstream valves without a manual blowdown routine.
Start with the port step: size 300 carries 3/8 in ports, and moving up to size 400 or down to size 200 changes both the connection and the flow path, so match the size to the air demand of the circuit. Because flow for this series is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering. From there the real choices are decodable: drain type (differential-pressure as fitted here, or automatic or manual by code), filter grade (40 um standard, 5 um with code W for finer particulate), gauge style and scale (this unit carries an external round gauge in psi; embedded square gauges and MPa/bar scales are order options), and thread family (PT is the catalogue standard, with G and NPT as order options - this unit is NPT). A mounting bracket is included on this configuration; code J deletes it. The low-pressure regulator type (code L) is selected where the circuit works below the standard regulator's range - confirm the exact setting range with us before ordering, as it is not published as a single figure.
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 performance curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing from the datasheet curves on request before you order.
The gauge is a coded choice. The embedded square gauge is the standard fitting on GFR units, while an external round gauge is an order option, and each is available on MPa, psi or bar scales. The C2 code on this model selects the external round gauge on a psi scale; if you need the square gauge or a different scale, that is a different code in the same series.
