The AirTAC GFR300C10LC2WG AirTAC Filter Regulator G3/8 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 AirTAC GFR300C10LC2WG is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is the 300 size with a G3/8 (BSPP) port, the 5 um filter element (code W) for finer filtration than the standard 40 um, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and the low-pressure regulator type for circuits that run at reduced settings. It carries a metal bowl, an external round pressure gauge with a psi scale, a mounting bracket, and no reverse/check valve. 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 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, standard or low-pressure regulation, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

On a cartoning or wrapping line, the GFR300C10LC2WG sits at the machine's air inlet to strip water and fine particulate before the valves and cylinders, while the low-pressure regulator holds the gentle setting that delicate clamp and pusher actuators need.
On a machining-centre clamping fixture fed at 3/8 inch, this unit filters the shop air to 5 um to protect the clamp cylinders and sequencing valves, and its low-pressure regulation keeps holding force at the reduced setting the fixture was designed around.
Looms and spinning frames run continuous compressed air through sensitive jet and nozzle components; this filter regulator at the frame inlet removes condensate and 5 um-level particles and drops the supply to the low pressure the nozzles require, with the psi gauge giving operators a local reading.
Choose the size and port step against the air consumption of the circuit downstream: 200, 300, 400 and 600 step up in port and flow capacity, and this unit sits at 300 with a G3/8 port. This example carries the 5 um element (code W); the standard grade is 40 um, so pick 5 um where finer particulate protection matters and 40 um for general-purpose prep. Drain choice is differential-pressure (as fitted here, self-bleeding on differential), automatic (A) or manual (M). The regulator here is the low-pressure type; its exact adjustment range is not published in our sheet, so confirm it with us if your setpoint is critical. Gauges are available as the embedded square type or an external round gauge in MPa, psi or bar scales - this unit has the round psi gauge. Threads come as PT (standard), G or NPT to order, and a mounting bracket is included on this configuration (code J deletes it). Flow for the G-series is published as curves, not a single rating, so 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 G-series flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your application's air consumption and line pressure and we will confirm the flow data from the datasheet and check the sizing for you before you order.
The code spells it out: W selects the 5 um filter element instead of the 40 um standard grade, and C2 selects the external round gauge with a psi scale instead of the embedded square gauge. The regulator is the low-pressure type, the drain is the differential-pressure type, and the bracket is included. If you would rather have the standard 40 um element, a bar or MPa gauge scale, or the standard regulator type, we can quote the matching GFR300 configuration.
