The AirTAC GFR30010LF2WT AirTAC Filter Regulator NPT3/8 5 um 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 GFR30010LF2WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This configuration has a 3/8 in NPT port, the finer 5 um filter element, a differential-pressure drain on the polycarbonate bowl, and a square pressure gauge reading in psi. The L in the code marks the low-pressure regulator type. 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 series is published in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, and psi, MPa or bar gauge scales. 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.

| F | Gauge shape: Square. C is round, F is square. |

| W | Filtering grade 5 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.

On a machining cell that hold-down clamps thin aluminium sheet, this unit filters the shop air to 5 um and holds a low, stable clamp pressure set on the psi gauge, keeping water and swarf-laden condensate out of the clamping cylinders.
A finishing line can use this low-pressure filter regulator on the atomizing air feed to a paint spray booth: the 5 um element keeps oil and water mist out of the finish while the regulator sets the low gun pressure the coating process calls for.
On a food packaging machine, low-pressure actuation of the sealing jaws runs on clean, regulated air: this unit filters condensate and particles to 5 um, the psi gauge lets the line set jaw pressure, and the differential-pressure drain handles collected water.
The real, decodable choices on a GFR unit are size and port, drain type, filter grade, regulator type, gauge scale and thread. This model is size 300 with a 3/8 in NPT port, the 5 um element, the low-pressure regulator type, a differential-pressure drain and a square psi gauge; mounting bracket included, no reverse/check valve. If your line needs coarser, lower-cost protection the 40 um element is the standard alternative, and G or NPT thread options exist to order. Flow for the GFR series is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm the right size 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-series flow as performance curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your required flow and working pressure and we will confirm sizing for the GFR30010LF2WT against the datasheet on request.
L marks the low-pressure regulator type, so this is the low-pressure variant of the GFR300 rather than the standard type. The exact adjustment range for the low-pressure type is not published in our data, so confirm the setpoint you need with us before ordering. The square gauge fitted on this model reads in psi.
