The AirTAC GFR300C15JF2WG AirTAC Filter Regulator G1/2, 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 AirTAC GFR300C15JF2WG is a size 300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/2 in port with G (BSPP) thread, a 5 um filter element for finer filtration than the standard 40 um grade, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. The standard regulator is adjusted across 0.15-0.9 MPa (20-130 psi), and the embedded square gauge reads in psi so set-points can be checked at a glance. No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale, thread (PT standard, G or NPT to order) and bracket. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet flow data 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.

Fitted at the point of use on a machine-tool air drop, it filters machining-fleet compressed air to 5 um and holds a steady regulated supply to the machine's pneumatic valves and clamps, with the psi gauge giving the setter a direct readout.
Mounted ahead of the cylinders on a carton-sealing or case-packing conveyor, it removes water carried over from the compressor and regulates the pressure that positions the flap-fold and tape-head actuators.
On a lab bench supply feeding air-operated sample valves or small process rigs, the 5 um element protects sensitive instrumentation from particles and the regulator lets the technician dial in the exact working pressure in psi.
Size 300 with a 1/2 in port sits in the middle of the GFR range; step up to size 400 or 600, or down to size 200, according to the air demand of the circuit. The 5 um element (code W) suits applications that need finer particle removal than the standard 40 um grade. The differential-pressure drain is the default: it discharges condensate automatically with the flow, with no operator attention; if you prefer timed or fully automatic draining regardless of differential, the A and M drain variants exist in the family. The square gauge here reads in psi; MPa and bar scales are also published. Thread is G (BSPP) on this unit, with PT as the standard thread and NPT available to order, and the bracket has been omitted (code J). Flow for this series is published as curves, not a single rating, so send us your application details 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 GFR300 series as performance curves rather than a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and we will confirm the flow data from the datasheet so you can size the unit correctly before ordering.
The W code in GFR300C15JF2WG selects the optional 5 um filter grade, which removes finer particles than the standard 40 um element. Use 5 um where downstream valves, cylinders or instruments need cleaner air; the standard 40 um grade remains available in the same family if your application does not require the finer filtration.
