The AirTAC GFR300C10AF2WTK AirTAC Filter Regulator NPT3/8 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 GFR300C10AF2WTK is an AirTAC GFR series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This configuration is a size 300 unit with a 3/8 in NPT port, a 5 um filter element (code W), an automatic drain that expels condensate from the polycarbonate bowl without manual attention, and a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi). An embedded square gauge with psi scale is fitted, a reverse/check valve is built in, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including manual or differential-pressure drains, a 40 um standard element, G (BSPP) or NPT threads in place of the PT standard, alternative gauge scales, and a low-pressure regulator type. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated supply to pneumatic clamping and tool-change cylinders on a machining center; the 5 um element helps protect pilot valves, and the psi gauge gives operators a setpoint check at the machine.
Air preparation for filler and capper actuator valves on a beverage line; the automatic drain handles condensate through continuous shifts, and the check valve holds the downstream setting if supply pressure dips.
Regulated air to diverter, stopper and pusher cylinders on a packaging conveyor; the square psi gauge makes setpoint verification quick during changeover, and the bracket simplifies mounting at the frame.
Size and port set the air capacity: this is a size 300 unit with a 3/8 in NPT port, and the right choice when your circuit needs more capacity than a size 200 passes - we confirm exact capacity against the published flow curves on request. The 5 um element (code W) suits finer pneumatic components and instrument air; the 40 um standard element is enough for general actuator supply. Drain choice: automatic (this unit) for unattended duty, manual for periodic service, or differential-pressure as the series default. Gauge scale can be ordered in MPa, psi or bar; thread can be PT (the standard), G (BSPP) or NPT; a mounting bracket is included here. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing 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 curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the datasheet flow figures and check the sizing against your demand before you order.
The A in the code fits an automatic drain, which expels collected condensate from the bowl without manual attention - useful on unattended or continuous-duty installations. Manual and differential-pressure drains are available in the same series if you prefer periodic or load-linked draining.
