The AirTAC GFR300C10JC2WGK 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 GFR300C10JC2WGK is an AirTAC GFR300 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body, sized for a G3/8 (3/8 in) port with G (BSPP) thread. This configuration carries the 5 um filter element (code W), a differential-pressure drain, a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), a round gauge reading in psi, and a built-in reverse/check valve (code K). No mounting bracket is included with the J suffix. 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 spans sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, plus a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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.

Filters and regulates the air feeding clamp and fixture cylinders on a machining cell, with the 5 um element in the supply line and the round psi gauge giving operators a direct setpoint readout at the machine.
Point-of-use filter regulator for pneumatic cylinders and diverters on a packaging conveyor, built with the check valve (code K) and a differential-pressure drain, set line-side with the psi gauge.
Conditions the air supply to a spray-painting booth or coating line, filtering the incoming air and regulating atomisation pressure at the point of use, with the drain dealing with collected moisture.
Choose the size step (200/300/400/600) and port to match the air demand of the circuit - this unit sits at size 300 with a 3/8 in G-threaded port. Drain type is a real choice: differential-pressure (as fitted here), automatic (A) or manual (M); filter grade is 40 um standard or 5 um with the W code, which this model carries. Gauge style and scale are selectable - embedded square or external round, in MPa, psi or bar; this unit has the round psi gauge fitted. Thread is PT as standard with G and NPT as order options, and the mounting bracket is optional (J = not included). Because flow is published as curves rather than one rated number, 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 GFR series as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number for this unit. Send us your application details and we will confirm the flow and the full datasheet figures for this exact model on request.
The W in the code orders the 5 um filter grade instead of the 40 um standard element. Both grades are catalogue options across the GFR range, and the 5 um element is chosen where the downstream circuit needs finer particulate removal. The rest of the specification - port, drain, gauge and regulation range - is unchanged.
