The AirTAC GFR30010LF2WG AirTAC Filter Regulator G3/8 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR300 series combines water and particulate filtration with pressure regulation in a single body. This GFR30010LF2WG is the 300 size with a G3/8 port, low-pressure regulator type, a 5 um filter element (code W), a polycarbonate bowl with differential-pressure drain, an embedded square gauge scaled in psi, and the mounting bracket included. No reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, 40 um standard or 5 um filtration, three drain choices and gauge scales in MPa, psi or bar. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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.

| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Cleaned and regulated supply air for the clamp cylinders on a CNC fixture, where the 5 um element protects the clamping valves and the low-pressure regulator holds the clamp circuit at its set point.
Point-of-use air preparation ahead of the low-pressure actuators on a carton-sealing or wrapping line, with the square psi gauge giving operators a clear local reading of the set pressure.
Filtered, regulated air for low-pressure air-knife or nozzle blow-off stations clearing dust and moisture from products moving along a conveyor, with the differential-pressure drain handling collected condensate.
Size steps from 200 through 600, each carrying a larger port and more flow, so pick the 300 / G3/8 frame against what your line needs and let us confirm the curve-based figures before you order. Drain here is differential-pressure, the standard choice; automatic (A) and manual (M) drains are available in the family. Filtration is the finer 5 um element (W) against the 40 um standard. The gauge is the embedded square type scaled in psi; a round external gauge and MPa or bar scales are options. This unit is ordered with G (BSPP) thread; PT is the standard thread and NPT is a catalogue option. Bracket included; a reverse/check valve can be specified (K) but is not fitted on this code.
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 series as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the datasheet flow figures against your required flow on request.
W selects the 5 um filter element instead of the 40 um standard. The finer grade suits sensitive downstream components such as precision valves and cylinders; if your application does not need fine filtration, the 40 um standard version of the same unit is available.
