The AirTAC GFR30010LC1TK AirTAC Filter Regulator NPT3/8 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 GFR30010LC1TK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This size-300 unit is built with a 3/8 in NPT port, the low-pressure regulator type, a 40 um filter element and a differential-pressure drain on the PC bowl. An external round gauge scaled in MPa is fitted, a reverse/check valve is included, and the mounting bracket is included. 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. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um element option (code W), gauge and scale choices, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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. 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 clamping cylinders on a fixture line with cleaned, moisture-reduced air held at the reduced pressure the clamp circuit was set up for, with the check valve holding the downstream side if supply dips.
Supplies filtered and regulated air to tool-change cylinders, chip gates and part clamps on a machining cell, where the 40 um element keeps grit and condensed water out of the actuator valves.
Conditions the air feeding vacuum ejectors and small cylinders on a packaging machine's handling stations, with the gauge letting operators verify setpoints during changeover.
Size and port are the first decision: the 200/300/400/600 steps pair with larger ports and more flow, and this unit sits at size 300 with a 3/8 in NPT port - match the step to your line's demand and we will confirm the curve against your application. Other real choices on this family: drain type (differential-pressure as here, automatic code A, or manual code M), filter grade (40 um standard, 5 um with W), gauge style and scale (MPa, psi or bar), thread (PT is the standard; G and NPT are order options), and bracket. The low-pressure type (L) is selected where the circuit runs at reduced pressures; its exact regulating range is not published, so confirm it with us. Because flow is published as curves and not a single rating, ask us to confirm sizing from the datasheet before ordering.
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 GFR300 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application's flow and pressure requirements and we will confirm sizing from the datasheet on request.
This unit leaves the drain position blank, which is the differential-pressure type: the PC bowl drains in service without a manual step. Automatic (code A) and manual (code M) drains are catalogue options on the GFR family if your installation needs them instead.
