The AirTAC GFR30010LF2T AirTAC Filter Regulator NPT 3/8 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 GFR30010LF2T is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit is threaded NPT 3/8 (the T suffix; PT is the catalogue standard, with G and NPT as order options) and carries the L code for the low-pressure regulator type, so it is intended for circuits that run at reduced pressure rather than full line pressure. Filtration is the standard 40 um element, condensate is handled by the differential-pressure drain, and an embedded square gauge reading in psi is fitted. The bowl on this size is polycarbonate (only size 600 uses aluminium alloy). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. A mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include automatic or manual drains, a 5 um (W) filter element, gauge scales in MPa, psi or bar, an external round gauge, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, 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 filtered air to spray guns on a paint or coating line, removing water and particles and holding a reduced pressure setting at the gun where full line pressure is too high.
Supplies filtered, reduced-pressure air to clamping circuits on a machining or welding fixture whose actuators are rated below the shop's full line pressure.
Conditions air for the cylinders and actuators on a packaging or bottling line, combining water and particulate removal with low-pressure regulation in one body.
Choose the size by port and expected flow: this unit is size 300 with 3/8 in NPT ports; larger sizes (400, 600) carry larger ports and more flow, while size 200 suits lighter duty. Drain type is a real choice: the differential-pressure drain fitted here discharges condensate as standard, while automatic (A) and manual (M) versions can be ordered. Filtration is 40 um standard; specify W for the 5 um element when finer filtration is needed. The embedded square gauge on this unit reads in psi; MPa or bar scales and an external round gauge are available. Threads can be ordered in G (BSPP) or NPT instead of the PT standard, and a mounting bracket is included. Because AirTAC publishes flow as curves rather than a single rating, send us your flow and pressure requirements 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
It marks the low-pressure regulator type. This unit is intended for low-pressure duty rather than standard full-range regulation; the exact adjustment range for the low-pressure version is not published in our sheet, so we confirm it on request. The standard (non-L) GFR range is also available.
