The AirTAC GFR300C15AJF2W AirTAC Filter Regulator PT1/2, 5 um 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 GFR300C15AJF2W is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is a 1/2 in PT port unit with a 5 um filter element (code W), an automatic drain, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), and an embedded square gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. It is supplied without a mounting bracket and without a reverse/check valve, and the bowl is metal.
This is a genuine AirTAC part. The GFR family covers filter regulators in 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 (W) filtration, square or round gauges scaled in MPa, psi or bar, an optional low-pressure regulator, an optional reverse/check valve, and G (BSPP) or NPT threads as order options alongside the PT standard. 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.

Conditioning and regulating the air feeding clamps, tool-changers and air-blast nozzles on a CNC machining cell, where the 5 um element protects fine-orifice components and the regulator holds the circuit at its set pressure.
Supplying filtered, regulated air to vacuum cups and gripper cylinders on a bottling or carton packaging line, with the automatic drain clearing condensate from the bowl without an operator having to bleed it by hand.
Feeding a bench-mounted pneumatic press or riveter in an assembly plant, where the square psi gauge lets operators set and check the working pressure against the process sheet at a glance.
Choose the size step (200/300/400/600) against the port and the flow your line needs; this unit is size 300 with a 1/2 in PT port. Pick the drain: differential-pressure (default), automatic (this unit) or manual - note the regulation range differs by drain type, with automatic and differential-pressure units adjusting 0.15-0.9 MPa (20-130 psi). Pick the element: 40 um standard or 5 um (W) as here. Gauges are embedded square as standard with an optional external round gauge, scaled in MPa, psi or bar. Thread is PT as standard, with G (BSPP) and NPT as order options; brackets are optional and this code omits one. 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. 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 here. Send us your application details and we will confirm the datasheet flow curve and sizing for you before you order.
The A in this code fits the automatic drain, which expels collected condensate without operator attention. Manual-drain (M) and differential-pressure (blank) versions of the same size are available; note the regulator adjustment range differs by drain type, and we can quote the variant you need.
