The AirTAC GFR30015JC2WTK AirTAC Filter Regulator NPT1/2 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 PT1/2" 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 GFR30015JC2WTK is an AirTAC GFR300 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration is built around a 1/2 in NPT port, a 5 um filter element for finer air cleaning than the standard 40 um grade, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is high enough. A round pressure gauge scaled in psi is fitted so the set pressure is visible at a glance, and an integrated reverse/check valve holds the downstream setting if upstream supply is interrupted. No mounting bracket is included with this code, so plan to support the unit from the connected pipework. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges scaled in MPa, psi or bar, and an optional reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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 a pneumatic assembly press with air that is both filtered to 5 um and held at a stable regulated pressure, so cylinder stroke speed and clamping force stay repeatable from cycle to cycle.
Conditioning the supply to diverters, stoppers and pusher cylinders on a packaging conveyor line, where the 5 um element protects valve spools from particulate and the regulator sets consistent actuation pressure.
Supplying bench-mounted lab equipment and pneumatic test rigs from a house air line, where finer 5 um filtration and a clearly readable psi gauge keep test conditions clean and repeatable.
Size and port: the GFR series steps through sizes 200, 300, 400 and 600, each with larger ports and higher flow capacity, so match the size to the air demand of the circuit rather than the pipe alone; this unit is size 300 with a 1/2 in NPT port. Drain type: differential-pressure (as here) drains with flow, automatic drains continuously regardless of flow, and manual drains need operator attention - pick according to how often the line runs unattended. Filter grade: 40 um is the standard element; the 5 um element fitted here suits finer applications such as air tools, valves and instrumentation. Gauge: embedded square gauges are standard with external round gauges optional, in MPa, psi or bar scales - this code carries a round psi gauge. Thread: PT is the standard, with G (BSPP) and NPT as order options. Bracket: included by default, omitted on this code (J). One honest note: flow for this series is published as curves, not a single rated figure, so 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. 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 characteristic curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment and we will confirm the relevant datasheet flow figures for this size 300 unit on request.
The W in the code selects the optional 5 um filter element instead of the 40 um standard grade. It gives finer removal of particulate and rust from the air stream, which suits air tools, directional valves and instrumentation. Everything else in the decode stays the same: 1/2 in NPT port, differential-pressure drain, round psi gauge, check valve fitted, and the same 0.15-0.9 MPa (20-130 psi) regulation range.
