The AirTAC AirTAC GFR400C10MJC2GK Filter Regulator 3/8 in G 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 GFR400C10MJC2GK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 400 configuration is supplied with a 3/8 in G (BSPP) port, a manual drain on the polycarbonate bowl, a 40 um standard filter element, a round pressure gauge reading in psi, and a built-in reverse (check) valve. It is ordered without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi) for this manual-drain version.
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 that include automatic, manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads in place of the PT standard, and a reverse valve. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Supplying cleaned, pressure-regulated air to a pneumatic press or clamping cylinder on a fabrication cell, where the check valve holds the set downstream pressure and the manual drain is emptied during scheduled changeovers.
Feeding air cylinders on a carton sealing or case packing conveyor, where water and scale carried in shop air would otherwise stick valves and the regulator keeps actuator speed consistent shift to shift.
Conditioning the air drop at a paint or coating station, where the 40 um element strips water and pipe scale ahead of the gun and the psi gauge lets the operator set and verify gun supply pressure.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a 3/8 in G port, one step up from the 300/1/4 in combination and one below the 600 series. The drain is the real operating decision: this version is manual, so someone drains the bowl periodically; automatic and differential-pressure drains are available on the same family, and note the regulator range differs by drain type (0.05-0.9 MPa / 7-130 psi for manual drain versus 0.15-0.9 MPa / 20-130 psi for automatic and differential-pressure versions). The 40 um element is standard; specify code W if the application needs 5 um filtration. The round gauge fitted here reads in psi; square embedded gauges and MPa or bar scales are alternatives. G thread is a catalogue option ordered in place of the PT standard, and a bracket can be added if this no-bracket version will be panel or wall mounted.
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the sizing against the datasheet curves before you commit.
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 family as curves, not as a single rated figure, so we do not quote a flow number on the page. Tell us your application - working pressure, downstream demand and acceptable pressure drop - and we will confirm the sizing from the datasheet curves on request before you order.
A manual drain means the accumulated water is released by opening the drain when needed, which suits installations that are checked regularly. The same GFR family is also available with an automatic drain or a differential-pressure drain (the standard). Note the regulator adjustment range depends on the drain type: 0.05-0.9 MPa (7-130 psi) for this manual-drain version, and 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure versions.
