The AirTAC GFR300C10ALC2TK 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 GFR300C10ALC2TK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built on the size-300 frame with a 3/8 in NPT port, an automatic drain that expels collected condensate without a daily manual round, and the standard 40 um filter element. The regulator is the low-pressure (L) type, a round gauge reading in psi is fitted, a reverse/check valve is built in, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the size-300 bowl is polycarbonate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um element option (code W), embedded square or external round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. AirTAC publishes flow for this series as curves rather than a single rated figure, so send us your application details and we will confirm sizing and datasheet figures on request.

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 cell's pneumatic clamps and tool-change cylinders, with the automatic drain keeping condensate out of valves at a point crews rarely visit.
Low-pressure regulated supply to spray guns and air-assisted applicators on a paint line, where the 40 um element and automatic drain help keep water and grit away from the finish.
Regulated air for carton-sealing cylinders and product diverters on a packaging conveyor, with the built-in check valve holding the circuit if upstream supply dips.
Every choice in this code is decodable. The 300 frame with a 3/8 in NPT port suits circuits plumbed at that size; step up to size 400 or 600 when the line calls for a larger port. The automatic drain suits points that are hard to reach on a maintenance round; choose manual where an operator drains by routine, or the differential-pressure default where drain timing should follow the pressure drop. The 40 um element is the standard grade; specify code W for the 5 um grade. The fitted round gauge reads in psi, while embedded square gauges and MPa or bar scales are catalogue options. NPT is the T order option - PT is the standard thread and G is also available - and the bracket is included on this code.
One honest note on sizing: AirTAC publishes flow for the GFR series as curves, not a single rated number, and the adjustment range of the low-pressure regulator type is not published either. Tell us your line pressure, set pressure and air demand and we will confirm the right size from 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and demand and we will confirm the flow from the datasheet for your application on request.
This unit is the low-pressure regulator type. Its exact adjustment range is not published in the catalogue, so we confirm the set range on request; maximum inlet pressure is 1.0 MPa (145 psi). If you need the standard adjustment span instead, ask us about the standard-type GFR300 in the same port and thread.
