The AirTAC GFR300C10AJF2WTK AirTAC Filter Regulator NPT3/8 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 GFR300C10AJF2WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 300-size unit is threaded NPT3/8 (3/8 in), carries a 5 um filter element (the W grade, finer than the 40 um standard), an automatic drain that clears condensate from the metal bowl without manual attention, and a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi). An embedded square gauge with a psi scale is fitted, a reverse/check valve is built in, and no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR300 series, one of four sizes (200/300/400/600) spanning ports from 1/8 in to 1 in, with manual, automatic or differential-pressure drains, 40 um or 5 um elements, MPa/psi/bar gauge scales and PT, G or NPT threads to order. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Feeding tool-clamp and chip-clearing cylinders on a CNC machining cell, where the 5 um element protects the directional valves and the regulator holds a steady clamp pressure.
Supplying stopper and lift cylinders on a bottling or carton packaging conveyor, with the automatic drain keeping condensate out of the valves through long unattended shifts.
Conditioning air to pneumatic presses and clamping fixtures on a small-parts assembly line, where the built-in check valve holds downstream pressure if the supply dips.
Choose the size and port against the air your line actually consumes: 300 with 3/8 in NPT sits mid-range in the GFR family, and stepping up or down changes both port and flow capacity. Drain type is a real decision - automatic (this unit) suits unattended duty, manual suits supervised points, and the default differential-pressure drain tracks flow; note the regulation range is 0.15-0.9 MPa (20-130 psi) with automatic or differential drains and widens to 0.05-0.9 MPa (7-130 psi) with a manual drain. Element grade is 40 um standard or 5 um (this unit, code W) for finer protection downstream. Gauge scale can be MPa, psi or bar (psi here), thread is PT as standard with G and NPT as order options, and a mounting bracket is optional (omitted here). Flow is published as curves, not a single rating - 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 flow for the GFR300 as curves rather than a single rated figure, so we do not quote one number. Send us your inlet pressure, set pressure and air consumption and we will confirm the sizing from the datasheet on request.
This unit carries code A, an automatic drain that ejects condensate from the bowl without attention - useful on lines that run unattended. Manual (code M) and the default differential-pressure drain are available in the same series; note the regulation range is 0.15-0.9 MPa (20-130 psi) with automatic or differential drains and 0.05-0.9 MPa (7-130 psi) with a manual drain.
