The AirTAC GFR300C10MC1TK 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 GFR300C10MC1TK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This 300-size unit is threaded NPT3/8, is ordered with a manual drain, carries the standard 40 um filter element, and comes with a round pressure gauge scaled in MPa. A reverse/check valve is fitted and the mounting bracket is included.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and can be ordered with automatic, manual or differential-pressure drains, a 5 um element (code W), embedded square or external round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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 air to a machining centre's tool-change and clamping circuits, with the manual drain bled during shift checks and the fitted check valve holding clamp pressure if the main supply dips.
Feeding stopper and pusher cylinders on a carton packaging line, where the regulator holds a steady setpoint so cylinder stroke timing stays repeatable through the shift.
Supplying actuator and positioner air to a pneumatic control valve on a water-treatment skid, with the 40 um element keeping grit out of the positioner and the round gauge giving a local pressure readout.
Start with the size and port: the 300 series steps up from the 200 series in both port and flow capacity, so match this 3/8 in NPT port against the air your circuit actually uses. Drain choice matters: this unit has a manual drain that you bleed by hand, so choose the automatic or differential-pressure drain versions if the installation is not visited daily. The standard element is 40 um; the W variant gives 5 um filtration. The round gauge on this unit reads in MPa, while embedded square gauges and psi or bar scales are catalogue options. PT is the standard thread and G (BSPP) or NPT are ordered options - this unit is specified in NPT. The bracket is included and the fitted check valve holds downstream pressure if the supply drops.
Flow for this family is published as curves, not a single rated figure, so no flow number is quoted here. Send us your flow and pressure requirements and we will confirm sizing against the AirTAC 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 GFR series 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 sizing from the datasheet on request.
This unit is ordered with a manual drain: accumulated water is bled from the bowl by hand, which suits attended installations. The same 300-size filter regulator can be ordered with an automatic or a differential-pressure drain for unattended duty. With the manual drain the regulation range is 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi).
