The AirTAC GFR30010C2WGK AirTAC Filter Regulator G3/8, 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 AirTAC GFR30010C2WGK is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one compact body. This 300-size unit is configured with a G3/8 (BSPP) port, a 5 um filter element for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically as flow passes through, an external round gauge reading in psi, and a built-in reverse (check) valve. The polycarbonate bowl suits this size, and the unit includes a mounting bracket.
This is a genuine AirTAC part from the GFR300 range, which spans sizes 200, 300, 400 and 600 with port options, drain types, filter grades, gauge styles and scales, and thread choices. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range for this drain configuration is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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. 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.

Feeds clean, regulated air to the tool-change clamping circuits of a CNC machining centre, where the 5 um element protects solenoid valves from fine particulate and the check valve holds settings if supply pressure dips.
Conditions the air feeding diverter and gate cylinders on a carton packaging line, keeping pressure steady at the setpoint so box pushes and product stops stay consistent through the shift.
Serves a bench-mounted drop for air impact drivers and nutrunners in an assembly cell, filtering line water before it reaches the tools and letting each operator read and adjust pressure in psi on the round gauge.
Choose the 300 size with its G3/8 port when your line sits between the smaller 200/1/4 in class and the larger 400/1/2 in class; the right step depends on the flow your application needs, which we can confirm against the published curves before you order. This unit carries the 5 um element (code W) instead of the standard 40 um grade - pick 5 um where downstream valves, cylinders or instruments need cleaner air, and 40 um where coarse water and chip removal is enough. The differential-pressure drain is the default: it needs no daily manual action, but a manual-drain version is available if you prefer controlled dumping. The round psi gauge suits US-style reading; square gauges and MPa or bar scales are alternatives. Thread here is G (BSPP); PT is standard and NPT is an order option. A bracket is included for panel or wall fixing. Ask us to check sizing against your flow requirement before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote one number. Send us your inlet pressure and required downstream flow and we will confirm the sizing from the datasheet curves before you order.
The W code in GFR30010C2WGK selects the optional 5 um element, which filters finer than the standard 40 um grade. It is the better choice when feeding sensitive valves, cylinders or instruments; if you only need coarse water and particle removal, the standard 40 um version of the same size is available.
