The AirTAC GFR300C10AF2T AirTAC Filter Regulator NPT3/8 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 GFR300 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration has a 3/8 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge reading in psi. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is published in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and with manual, automatic or differential-pressure drains, 40 um or 5 um (code W) elements, MPa, psi or bar gauge scales, and G (BSPP) or NPT threads as order 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.

Feeding clean, regulated air to a machine tool's tool changer and clamping actuators, where the automatic drain clears condensate through long production shifts without operator attention.
Supplying carton-sealing and case-erector cylinders on a packaging conveyor, with the 40 um element protecting directional valves and the regulator holding a steady setpoint for consistent stroke action.
Providing filtered, regulated air to pneumatically actuated process valves on a skid, with the square psi gauge letting technicians set and verify the actuator pressure locally.
Size and port step up together across the GFR range (200/300/400/600), so choose the size whose flow curve covers your demand at your working pressure - this 300 unit carries a 3/8 in NPT port. Drain choice is a real decision: automatic (fitted here) suits unattended duty, manual suits periodic checks, and differential-pressure drain versions are also available in the series. The 40 um element is standard; specify 5 um (code W) for finer protection. The gauge here is the embedded square type reading in psi; MPa and bar scales are available, and an external round gauge is an option. PT is the standard thread, with G (BSPP) and NPT as order options, and a mounting bracket is included.
Flow for this series is published as curves, not a single rated number, so send us your flow and pressure requirements 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 as curves rather than a single rated figure, so we do not quote one number. Tell us your flow and working pressure and we will confirm sizing from the datasheet on request before you order.
This configuration is fitted with an automatic drain, which ejects collected condensate on its own - useful for unattended or continuous duty. Manual and differential-pressure drain versions exist in the GFR series, and the 5 um element (code W) plus MPa, psi or bar gauge scales are order options.
