The AirTAC GFR300C10ALJF2GK AirTAC Filter Regulator G3/8 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 GFR300C10ALJF2GK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built with a G3/8 (BSPP) port, the 40 um standard filter element, an automatic drain, and the low-pressure regulator type. The embedded square gauge is fitted with a psi scale, a reverse/check valve (code K) is included, and no mounting bracket is supplied with this unit.
It is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), and gauge scales in MPa, psi or bar. 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 the 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.

Feeding filtered, regulated air to the clamp cylinders on a machining fixture: the 40 um element strips water and particulate before the regulator sets the circuit pressure, and the fitted reverse/check valve backs up the line.
Supplying diverters, pushers and sealing actuators on a packaging conveyor: the automatic drain discharges collected condensate without operator attention, keeping the bowl serviced through unattended shifts.
Regulating supply air to a glue head or coating nozzle circuit that calls for the low-pressure regulator type, with the square psi gauge giving a direct readout of the set pressure at the point of use.
Pick the size by the port and flow step: this unit is size 300 with a 3/8 in port, and larger sizes in the family move more air - match the step to your circuit's demand rather than to any single rated figure. The drain here is automatic (code A); the family also offers manual (M) and differential-pressure (blank) drains, with automatic suiting unmanned or hard-to-reach installations. The element is the 40 um standard grade - specify code W if the application needs the 5 um grade. The gauge is the embedded square type with a psi scale; MPa and bar scales are orderable. The regulator is the low-pressure type, and its exact adjustment range is not published, so confirm it with us before ordering. Thread on this unit is G (BSPP), with PT and NPT available as order options; brackets are optional and not included here. Because flow is published as curves, not a single rating, 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 GFR300 flow as curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your application details and we will confirm the flow and sizing figures from the datasheet on request.
This unit carries drain code A: an automatic drain that discharges collected condensate from the bowl without manual intervention. The GFR family also offers a manual drain (code M) and a differential-pressure drain (blank), selectable when ordering.
