The AirTAC GFR300C10JF1TK AirTAC Filter Regulator NPT3/8, Square Gauge 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 GFR300C10JF1TK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit is specified with an NPT3/8 port, a 40 um filter element, a differential-pressure drain, and the standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range. It carries an embedded square gauge scaled in MPa, a reverse/check valve, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl on this 300 size is PC (polycarbonate).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include automatic or manual drains, a finer 5 um element (code W), gauge scales in psi or bar, G (BSPP) or NPT threads, and mounting brackets. 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.

Fitted at the drop feeding a CNC machining center, this unit strips water and chips-scale particulate from the shop air and holds a set regulated pressure to the tool changer, clamps and air cylinders on the machine.
Mounted ahead of the valve manifold on a cartoning or bottling line, it delivers clean, regulated air to the packaging cylinders and diverters, with the built-in check valve helping hold the downstream setting if upstream supply dips.
Installed at each workbench drop in an assembly plant, it gives operators filtered, pressure-set air for hand tools, air clamps and small presses, keeping the setting stable line-wide from one size 300 unit per station.
Pick the size and port against the flow your line needs: 200, 300, 400 and 600 step up in port and capacity, and this unit sits at size 300 with an NPT3/8 port. Decide the drain type - differential-pressure (as ordered here), automatic, or manual - noting the regulation range differs by drain type. Choose the filter grade: 40 um standard or 5 um (code W) for finer filtration. Select the gauge scale (MPa, psi or bar) and the thread: PT is the standard, with G (BSPP) and NPT as order options - this unit is specified NPT. Brackets are optional, and this configuration is ordered without 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 GFR300 as curves rather than a single rated figure, so no single flow number is quoted here. Send us your application details and we will confirm the flow and full datasheet figures for this exact unit on request.
PT is the standard thread for the G-series, with G (BSPP) and NPT available as order options. This GFR300C10JF1TK is specified with the NPT option, giving a 3/8 in NPT port; order the same model with the PT or G thread code if your piping uses those standards.
