The AirTAC GFR400C15MJC2GK AirTAC Filter Regulator G1/2 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 GFR400C15MJC2GK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This GFR400 configuration has G1/2 (BSPP) ports, a 40 um standard filter element, a polycarbonate (PC) bowl with manual drain, a built-in check (reverse) valve, and a round pressure gauge reading in psi. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across the series include automatic or manual drains, a 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, PT, G or NPT threads, and brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet 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.

Point-of-use water and particulate removal plus a set downstream pressure for the air feeding clamps and pneumatic actuators on a machining center; the manual drain is emptied during scheduled shop maintenance.
Filtered, regulated air for the pick-and-place cylinders and grippers on a bottling or cartoning conveyor, with the round psi gauge giving operators a local setpoint readout at the line.
A stable, regulated supply for benchtop pneumatic test rigs and lab automation, where the 40 um element handles water and particulate ahead of the rig and the psi gauge supports repeatable setups.
Step through the GFR200/300/400/600 sizes to match the port and flow your line needs - this 400-size unit carries G1/2 here, and the thread position also decodes to PT (standard) or NPT on other codes. Choose the drain: manual (this unit, code M) means the bowl is drained by hand on a routine; automatic (A) and differential-pressure (blank) drains are available on other codes. Filter grade is 40 um standard on this unit; specify W for the 5 um element where finer particulate capture matters. For the gauge, this code carries an external round gauge with a psi scale; the embedded square gauge and MPa or bar scales are the alternatives. No mounting bracket is included with this code; brackets are optional.
Flow for this family is published as curves, not a single rated number, 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 the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
M is the manual drain: the bowl is emptied by hand as part of routine maintenance instead of automatically. If you prefer unattended drainage, the GFR family is also available with automatic (code A) or differential-pressure (blank) drains on other codes.
