The AirTAC GFR400C10MJC2TK 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 GFR400C10MJC2TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 3/8 in NPT ports, a manual drain bowl, a 40 um standard filter element, a round pressure gauge reading in psi, and a built-in reverse (check) valve that holds downstream pressure if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC); the manual drain means an operator opens the drain to expel collected condensate.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, a 5 um optional element (code W), gauge styles and scales, G (BSPP) or NPT thread options, and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application 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.

Installed ahead of an air-operated press or clamp cylinder circuit, it cleans the supply and holds a set working pressure so the press cycle repeats under consistent air conditions.
Feeding the cylinder and actuator drops on a packaging or cartoning line, it strips condensate and pipe scale from the shop air and lets the line set the pressure each station needs.
On a test rig or laboratory bench, the psi gauge and check valve let a technician set and hold a stable regulated pressure while the 40 um element protects sensitive instruments from water and dirt.
Size 400 with 3/8 in NPT ports suits lines where the required flow sits in the upper mid-range of the G-series; step up to size 600 for larger demand or down to 300/200 for compact circuits - match the size to the flow curve, not to the port alone. The manual drain (code M) is the right choice when an operator is present at intervals; choose automatic or differential-pressure drains for unattended installations. The 40 um element is standard; specify the 5 um W option if downstream equipment needs finer filtration. The round psi gauge (code C2) is fitted here; embedded square gauges and MPa/bar scales are alternatives. NPT thread is ordered as the T option (PT is the standard thread; G/BSPP is also available), and this unit ships without a mounting bracket (code J) - order a bracket if you want panel or wall fixing. Because flow is published as curves rather than 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number here. Tell us your application and we will confirm the datasheet and check the sizing against your required flow on request.
The M in the code means the bowl drain is opened by hand to expel collected condensate, which suits installations with periodic operator attention. The GFR family is also available with a differential-pressure drain (the default) or an automatic drain (code A) - ask us for the equivalent model if you prefer an unattended drain.
