The AirTAC GFR30015JF1WTK 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 GFR30015JF1WTK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is a 1/2 in NPT unit with a 5 um filter element, a differential-pressure drain, an embedded square gauge scaled in MPa, and a reverse (check) valve fitted; it is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the regulation range for this differential-pressure-drain version is 0.15-0.9 MPa (20-130 psi). The bowl is polycarbonate (PC); only size 600 units in the family use an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT (standard), G or NPT threads, 40 um standard or 5 um (W) filtration, manual, automatic or differential-pressure drains, and gauge options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

Point-of-use filtration and regulation feeding the machine's pneumatic valves and actuators: the 5 um element screens particulate before directional valves, and the check valve holds the circuit during upstream pressure dips.
Regulating and cleaning supply air to carton-forming and sealing cylinders on a packaging line, where the differential-pressure drain sheds condensate during production flow without interrupting the cycle.
Setting a stable working pressure at the spray-gun take-off, with the 5 um element helping keep moisture and particles out of the air line ahead of the gun.
Match the size and port to the air demand of the line: this unit is size 300 with a 1/2 in NPT port. Drain choice matters in use: differential-pressure (this unit) drains condensate while air flows, automatic drains continuously, and manual drains on demand. Filtration is 40 um as standard or 5 um (code W) where finer filtration is needed - this unit carries the 5 um element. The embedded square gauge is scaled in MPa, with psi and bar scales available as order options, and the fitted reverse/check valve holds downstream pressure during upstream pressure loss. Threads are PT as standard with G and NPT as catalogue options, and brackets are optional. Flow is published as curves, not a single rating, 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.
Flow for the GFR300 series is published as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your air demand and line pressure and we will confirm sizing and the full datasheet figures on request.
W marks the 5 um filter element instead of the 40 um standard grade. This unit carries the 5 um element, which suits applications that need finer filtration; if you prefer the standard 40 um grade, order the same model without the W.
