The AirTAC GFR300C10AJC1T 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 GFR300C10AJC1T is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit is threaded NPT3/8 (3/8 in) and is fitted with an automatic drain, a 40 um filter element, a round pressure gauge scaled in MPa, and no mounting bracket. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, G, NPT or PT threads, manual, automatic or differential-pressure drains, an optional 5 um element, and a choice of gauge styles and scales. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding clean, regulated air to a machine tool's pneumatic actuators and tool-clamp circuits, with the automatic drain handling condensate through unattended shift changes.
Conditioning the air that drives carton-forming and case-sealing cylinders, keeping moisture and debris out of directional valves while holding a steady set pressure downstream.
A point-of-use filter regulator on a drop from the plant air main, giving workstations a local pressure setting and a 40 um barrier ahead of air tools and fixtures.
Size and port set the flow path: this unit is size 300 with a 3/8 in NPT thread, and you can step up or down through sizes 200 to 600 as your line's air demand requires. Drain choice matters in service: automatic (as specified here) expels condensate without attention, manual needs periodic bleeding, and the blank code gives a differential-pressure drain. The filter element is 40 um standard or 5 um with code W. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; the thread is PT as standard with G and NPT as order options, and brackets are optional. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against 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 GFR300 as curves rather than a single rated figure, so there is no one number we can quote here. Send us your application details and we will confirm the flow and full datasheet figures on request before you order.
This unit carries code A, the automatic drain, which expels collected condensate without manual attention - useful on lines that run unattended. Manual (code M) and differential-pressure (blank code) drains are available on other GFR300 variants if your service routine suits them better.
