The AirTAC GFR300C10JF1T 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 GFR300C10JF1T is a filter regulator: a water-and-particulate filter and a pressure regulator built into one body, so a single 3/8 in (NPT3/8) connection both cleans the compressed air and holds downstream pressure steady. This configuration is the size 300 unit with the 40 um standard filter element, a differential-pressure drain that discharges collected condensate when the pressure drop across the element rises, and a square pressure gauge fitted on MPa scale so setpoints can be read and adjusted directly. The standard regulator covers 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), the bowl on this 200/300/400 size is polycarbonate, and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is included with this code and no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and PT, G (BSPP) or NPT threads. Across the series you can order a 5 um element (code W), automatic or manual drains, gauge scales in MPa, psi or bar, an external round gauge, and a mounting bracket where the code calls for one. Flow for GFR units 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.

Cleaning and regulating the shop-air feed to a machining centre's tool-clamp cylinder, so clamp pressure holds steady through the shift and element-passed water never reaches the clamp valve.
Conditioning the air to diverter, stopper and pusher cylinders on a bottling or carton conveyor, knocking condensate and particles out before they reach the line valves.
Point-of-use filtration and regulation for positioner pilot supply on a process skid, holding a stable setpoint to the positioner with the MPa gauge matching plant instrument readouts.
Choose the size by the port and flow your line needs: sizes 200 through 600 step up in port from 1/8 in to 1 in, and this GFR300 sits at 3/8 in NPT. Pick the drain to match the duty: differential-pressure (this unit) discharges on pressure drop across the element, automatic drains on its own cycle, and manual needs an operator - note the manual-drain version widens the regulating range down to 0.05-0.9 MPa (7-130 psi). Filter grade is 40 um standard or 5 um with code W where finer cleanliness matters. Gauge options are the embedded square gauge (fitted here, MPa scale) or an external round gauge in MPa, psi or bar scale. Thread is PT as standard with G (BSPP) and NPT as order options - this code is NPT. Code J means no mounting bracket is supplied. Flow is published as curves, not a single rating, so send us your air 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the datasheet curve and check the sizing for your application on request.
This code leaves the drain position blank, which is the differential-pressure type: condensate is discharged when the pressure drop across the filter element rises. If you prefer self-acting draining or a bowl emptied by hand, automatic (A) and manual (M) drain versions are order options - the manual-drain version also widens the regulating range to 0.05-0.9 MPa (7-130 psi).
