The AirTAC GFR300C10F2TK AirTAC Filter Regulator NPT 3/8 in 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 GFR300C10F2TK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a 3/8 in NPT port. This configuration carries a 40 um filter element, a differential-pressure drain on the polycarbonate bowl, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). An embedded square gauge with a psi scale is fitted, a reverse/check valve holds the downstream setting, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range 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 that include a 5 um element (code W), automatic or manual drains, gauge scales in MPa or bar, G (BSPP) or NPT threads, and low-pressure or no-gauge variants. 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.

Fitted ahead of a CNC machine's air drops, it removes water and pipe-scale from the shop supply and holds a steady regulated pressure to clamps and actuators, while the check valve keeps the setting during upstream pressure dips.
On a packaging conveyor line it conditions the air feeding pick-and-place and sealing cylinders: the 40 um element protects directional valves from particulate, and the differential-pressure drain clears collected condensate without stopping the line.
At assembly-station tool drops it delivers clean, regulated air to impact drivers and fixtures; the psi-scale gauge lets technicians set and verify station pressure at a glance, and the check valve prevents decay between cycles.
Choose the size by port step against the air your line needs: 200 serves 1/8-1/4 in ports, 300 covers 3/8-1/2 in, 400 covers 1/2-3/4 in and 600 covers 1 in, with larger sizes passing more air. On a GFR300 you can select the drain (differential-pressure as here, automatic, or manual - note the manual-drain version widens the regulating range down to 0.05 MPa / 7 psi), the filter grade (40 um standard or 5 um with code W), the gauge (embedded square as standard with MPa, psi or bar scales, or an external round gauge), the thread (PT is the standard; G and NPT are ordered as specification options), and whether to fit a reverse/check valve or omit the bracket.
Because AirTAC publishes flow for this family as curves rather than a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm the datasheet figures and the correct size 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet flow curves and check the sizing against your demand before you order.
This configuration uses a differential-pressure drain, and with that drain the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). If you need regulation down to 0.05 MPa (7 psi), the manual-drain version of the same GFR300 size covers it - we can quote that variant on request.
