The AirTAC GFR400C10MJC3TK AirTAC Filter Regulator 3/8 in NPT 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 GFR400 series combines water and particulate filtration with pressure regulation in a single body. This unit is the size 400 frame with a 3/8 in NPT port, a manual drain on the bowl, a 40 um standard filter element, an external round gauge reading in bar, and a built-in reverse (check) valve that holds the downstream setting if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series filter regulator range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, gauge scale options and G/NPT thread variants. At size 400 the bowl is polycarbonate; only size 600 uses aluminium alloy. Published flow data appears as curves rather than a single rating, so ask us to confirm figures 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.

Feeds filtered, regulated air to a press cylinder, with the check valve holding the set pressure if the shop supply dips mid-stroke.
Supplies clean, regulated air to the cylinders and grippers on a carton-forming and sealing line, with the round bar gauge giving operators a local pressure readout.
Regulates air to sortation diverters and stoppers along a conveyor, removing water and particulate before it reaches the gate cylinders.
Size and port set the air capacity: step up from 400 (3/8 in) to 600 (3/4 in or 1 in) when the line needs more flow, or down to 300/200 for compact points of use. Drain choice matters: manual drain needs an operator to bleed the bowl, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um as standard; specify W for 5 um where finer protection is needed. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket are all decodable options.
Flow for this series is published as curves, not a single rated figure, so send us your flow and pressure requirements 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 this series as curves rather than a single rated figure, so we do not quote a number on the page. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
M means the bowl is drained by hand, which suits installations an operator already visits regularly. If you want the bowl emptied without attention, the same series is available with an automatic drain (code A) or the differential-pressure drain (blank), and the 0.05-0.9 MPa regulation range applies to the manual-drain version.
