The AirTAC GFR300C15MJC2WTK AirTAC Filter Regulator NPT1/2 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 GFR300C15MJC2WTK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This configuration is built for a 1/2 in NPT port, filters to 5 um (the finer of the two catalogue grades), drains by hand through the manual drain, carries a round pressure gauge reading in psi, and has a reverse (check) valve fitted. No mounting bracket is included with this code. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family runs in four sizes (200, 300, 400 and 600) with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um filtration, embedded square gauges or optional external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for 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.

Feeding clean, regulated air to the tool-clamp and actuator circuits on a CNC machining centre, where the 5 um element protects fine control valves and the round psi gauge lets setters read setpoints directly.
Regulating air to the pick-and-place cylinders and sealing jaws on a packaging conveyor, with the fitted check valve isolating the regulated circuit from supply-pressure dips.
A filter-regulator station on assembly plant air drops, where operators drain the bowl by hand at shift start and adjust branch pressure with the round psi gauge.
Size and port set the air capacity: the 300 body on this unit takes a 1/2 in NPT connection, one step up from the 200 series, with the 400 as the next step if your demand grows. Drain type is a real service choice: manual (as here) suits points an operator visits regularly, while automatic and differential-pressure drains suit unattended lines - note that with a manual drain the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). The 5 um element (code W) is the finer option over the standard 40 um where downstream valves or instruments need cleaner air. The gauge on this code is the external round type reading psi; MPa and bar scales are catalogue options. Thread is NPT here; PT is the standard thread and G (BSPP) is also available to order. Flow for the GFR series is published as curves, not a single rating - send us your pressure and air demand and we will confirm sizing against 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 number. Tell us your working pressure and air demand and we will confirm the sizing against the datasheet on request.
This unit drains by hand, which suits positions an operator visits regularly; with a manual drain the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). For unattended lines the same body is available with automatic or differential-pressure drains - ask us and we will quote the variant.
