The AirTAC GFR30010LF2W AirTAC Filter Regulator PT3/8, 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 GFR30010LF2W is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the size 300 unit with a PT3/8 (3/8 in) port, the finer 5 um filter element, the low-pressure regulator type, a differential-pressure drain, and an embedded square gauge reading in psi. A mounting bracket is included, and the polycarbonate bowl suits the 300 size. 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 is published in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

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.

Filtered, regulated air to the clamping cylinders on a CNC fixture, where the low-pressure type and 5 um element keep actuation air clean and held at the set point the fixture was designed around.
Supplying conditioned air to the divert cylinders and gate actuators along a sorting conveyor, with the differential-pressure drain carrying condensed water away during continuous line running.
Conditioning the air feeding nozzles and pilot valves on a laboratory or pilot-scale coating and dosing skid, where the 5 um grade protects fine orifices and the psi gauge gives a familiar set-point readout.
Step the size and port (200 through 600, 1/8 to 1 in) against the air demand of the downstream circuit, and pick the drain type that matches your maintenance access: differential-pressure as fitted here, automatic, or manual. Choose 40 um for general circuit protection or 5 um, as on this unit, where finer particle removal matters. Gauge scale (MPa, psi or bar), PT versus G or NPT thread, standard versus low-pressure regulation, and the bracket are all fixed at order time. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this size 300, 3/8 in unit on request.
It marks the low-pressure regulator type. The exact adjustment range for the low-pressure version is not published in the standard tables, so we confirm it on request; the 1.0 MPa (145 psi) maximum inlet pressure and the rest of this unit's specification are unchanged.
