The AirTAC GFR300C10C2WGK AirTAC Filter Regulator G3/8, 5 um 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 GFR300C10C2WGK is an AirTAC GFR filter regulator: water and particulate filtration plus pressure regulation combined in one body, with no lubricator. This configuration is a size 300 unit on a G3/8 (3/8 in) G-thread port, fitted with the 5 um filter element, a differential-pressure drain, a round pressure gauge reading in psi, a reverse/check valve and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator setting range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part from the GFR300 series. The G-series filter regulators span sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and a reverse/check valve. Flow figures are published as curves rather than a single rating, so contact us and we will confirm the datasheet figures for your application on request.

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 ahead of clamping cylinders: the 5 um element strips water and fine particulate before the clamp valves, and the regulator holds a steady clamp pressure with the psi gauge in view of the operator.
Feeding the sealing-arm cylinders of a case-packing station with filtered, regulated air, while the reverse/check valve holds the set pressure against upstream fluctuations during machine cycling.
Supplying pilot air to solenoid valves and small actuators on an automated benchtop rig, where the 5 um grade protects fine internal clearances and the regulator keeps actuation pressures repeatable.
The GFR300 size sits in the G-series step from 1/8 in to 1 in ports, so move up or down a size when the air demand of the line changes. This code carries the 5 um element (W) instead of the 40 um standard, a differential-pressure drain, a round gauge on the psi scale, a reverse/check valve and a mounting bracket. Thread on this unit is G (BSPP); PT is the standard thread and NPT is available to order. Drain choice matters in practice: differential-pressure drain suits steady demand, automatic drain suits unattended points, and manual drain suits periodically checked installations.
Flow for the GFR series is published as performance curves, not as a single rating, so ask us to confirm sizing against your application from the datasheet 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.
Rated flow is not published as a single number for the GFR series; AirTAC publishes it as performance curves. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
W is the filter-grade code for the 5 um element. The standard GFR element is 40 um; choosing 5 um gives finer particulate removal upstream of sensitive valves and instruments. This unit also has a differential-pressure drain, a round gauge reading in psi and a reverse/check valve.
