The AirTAC GFR300C10LF2WG AirTAC Filter Regulator G3/8 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 See datasheet 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 GFR300C10LF2WG is an AirTAC GFR300 filter regulator: a 5 um filter element and a low-pressure regulator combined in a single body. This configuration has a G3/8 (BSPP) port, a differential-pressure drain that bleeds accumulated condensate whenever the pressure differential across the element rises, a metal bowl, an embedded square gauge reading in psi, and a mounting bracket. It removes water and particulate from compressed air and holds a reduced, low-range working pressure downstream. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part in the GFR300 size family, one of four sizes (200, 300, 400, 600) that step up in port and flow capacity, with manual, automatic or differential-pressure drains, 40 um or 5 um elements, standard or low-pressure regulator types, and PT, G or NPT threads. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm the flow 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

Point-of-use conditioning for a CNC machining centre: the 5 um element strips water and fine particulate before they reach the machine's solenoid valves, while the low-pressure regulator holds the reduced pressure the machine's low-pressure circuit calls for and the psi gauge gives a direct read.
A power-clamping circuit on an assembly fixture that runs at reduced pressure: the regulator holds the clamp set-point, the square psi gauge lets the operator verify it at a glance, and the filter keeps scoring particles out of the clamp cylinder.
Conditioning the compressed air feeding a laboratory bench or test rig where instruments and small actuators need clean air at a low regulated pressure, with the differential-pressure drain clearing condensate automatically during pressure swings.
Size and port: GFR300 carries a G3/8 port; step up to GFR400 or GFR600 when the circuit's air demand outgrows 3/8 in piping, or down to GFR200 for smaller lines. This unit is the low-pressure regulator type (code L); the standard type is available if your circuit works at ordinary regulated pressures. Filter grade: this one carries the 5 um element (code W) for finer protection; the 40 um standard element suits general-duty upstream use. Drain: differential-pressure here, with automatic and manual variants offered. Gauge: embedded square, psi scale; MPa or bar scales and an external round gauge are alternatives. Thread: this unit is G (BSPP); PT is the standard thread and G and NPT are order options. Bracket included. Because flow is published as curves rather than a single rating, 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 number, so we do not quote a rated flow figure. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this exact model before you order.
The L in the code marks the low-pressure regulator type; the exact regulated range for this variant is not published in the catalogue, so we confirm it on request. If your circuit works at ordinary regulated pressures, the standard-type GFR300 in the same G3/8 port is the alternative - we can decode the right variant for you.
