The AirTAC GFR300C10C2WG AirTAC Filter Regulator 3/8 in G Thread 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 GFR300C10C2WG is an AirTAC GFR300 filter regulator: a 300-size unit that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is threaded G3/8 (G/BSPP), carries the optional 5 um filter element, drains the bowl by differential pressure, and is fitted with a round pressure gauge reading in psi. The standard regulator covers 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing). The polycarbonate bowl is standard at this size, and a mounting bracket is included.
This is a genuine AirTAC part. The G-series filter regulator range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include manual or automatic drains, a 40 um standard element, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow data is published as curves rather than a single rating, so ask us to confirm the 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. 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.

Filter-regulated air for a carton-sealing and stretch-wrapper cell: the 5 um element keeps water and scale out of solenoid valves while the regulator holds a steady setting to the wrapper's clamp cylinders.
Air preparation for a CNC cell's pallet-clamp and chip-door circuits: the 3/8 in port feeds the manifold, the psi gauge gives operators a readable setpoint, and the differential-pressure drain keeps the bowl clear during shift runs.
Supply for a distribution-centre conveyor's diverter and stopper cylinders: regulation across 0.15-0.9 MPa lets each lane be tuned individually, and the 5 um grade protects the directional valves from particulate in the plant air.
Size and port set the flow path: the 300 frame with a 3/8 in port suits lines one step above 1/4 in point-of-use drops; step up to 400/600 or down to 200 as demand changes. Choose the drain to match the duty - differential-pressure (this unit) drains only when the pressure drop across the element demands it, automatic suits unmanned installations, manual suits attended ones. The 5 um element (code W) is the tighter grade; the 40 um standard element is available if your air is already pre-filtered. Gauge scales come in MPa, psi or bar, and threads can be ordered in PT, G or NPT.
Flow for this family is published as curves, not a single rated figure, so send us your application details and we will confirm sizing from the datasheet before you order.
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 GFR300 series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application - inlet pressure, set pressure and the air demand of the equipment - and we will confirm the sizing from the datasheet before you order.
The W in the code selects the optional 5 um grade; the catalogue standard is 40 um. The tighter element suits lines with sensitive valves or downstream equipment, while 40 um is the usual choice for general plant air. Both grades are catalogue options on the GFR300 frame.
