The AirTAC GFR30015AJC1WT 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 automatic 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 GFR30015AJC1WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your set point. This configuration has 1/2 in NPT ports, the finer 5 um filter element (W grade, against the 40 um standard), an automatic drain that bleeds collected condensate from the polycarbonate bowl without daily attention, and a round external pressure gauge reading in MPa. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range; no mounting bracket and no reverse/check valve are fitted.
It is a genuine AirTAC part from the catalogue GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, manual, automatic or differential-pressure drains, 40 or 5 um elements, and square or round gauges scaled in MPa, psi or bar. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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 paint or coating booth drop: the 5 um element keeps water carryover and fine particles out of the finish while the regulator holds the atomizing air at the set pressure the operator dials in.
Supplying a bench press or clamping fixture where repeatable clamp force depends on steady downstream pressure; the automatic drain clears condensate on a machine that runs unattended between shifts.
Protecting the solenoid valves and cylinders on a packaging conveyor: filtered, regulated air at each station, with the auto-drain bowl handling the moisture a long supply line collects.
Size the unit by port and expected air demand: this GFR300 carries 1/2 in ports, stepping up to GFR400 or GFR600 gives larger ports and more flow, while GFR200 suits smaller lines. This model has the 5 um element - choose the 40 um standard grade where only bulk water and coarse particles are the concern. The automatic drain suits unattended duty; manual and differential-pressure drains are also catalogue options. The gauge here is the round external type on an MPa scale; the embedded square gauge and psi or bar scales can be ordered instead. Thread is NPT on this unit; PT is the standard and G (BSPP) is also available to order, and a mounting bracket is optional if you want the unit secured independently of the piping. Because flow is published as curves rather than a single rating, send us your line size and 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 GFR300 flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow curve and the datasheet for this exact model on request.
The A code on this model fits an automatic drain, which bleeds collected condensate from the bowl by itself instead of relying on someone opening a manual drain. Manual and differential-pressure drains are also catalogue options on the GFR300 if you prefer them.
