The AirTAC AirTAC GFR400C10MJF2GK Filter Regulator, G3/8, Gauge 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 GFR400C10MJF2GK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for a G3/8 (3/8 in) port. This configuration carries a manual-drain polycarbonate bowl, a 40 um filter element (5 um is available as code W), a standard regulator adjustable from 0.05 to 0.9 MPa (7-130 psi), an embedded square gauge reading in psi, and a built-in reverse/check valve. No mounting bracket is included with this variant. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including automatic or differential-pressure drains, 5 um filtration, alternate gauge scales (MPa, psi, bar), an external round gauge, a mounting bracket, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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 filter regulator cleaning and setting supply pressure for machine-tool pneumatics such as tool-clamp and chip-clearing circuits on a machining centre.
Filtered, regulated air for clamp and pusher cylinders on a carton packaging line, with the check valve holding the set downstream pressure against supply dips.
A filter-regulator at an assembly bench air drop, protecting hand tools and small actuators from water and scale while holding a stable working pressure.
Choose the size by port and duty: this unit is size 400 with a G3/8 port; the smaller 200/300 and larger 600 sizes step port and flow capacity down or up. Drain type is a real decision: this unit has a manual drain, which needs periodic bleeding, while automatic and differential-pressure drain variants handle condensate continuously. Filtration here is the 40 um standard element; specify code W for 5 um where downstream equipment needs finer protection. The fitted square gauge reads in psi; MPa and bar scales are available and an external round gauge is optional. The thread on this unit is G (BSPP); PT is the standard and NPT is an order option. A mounting bracket is optional and not fitted here. 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.
Flow for the GFR400 is published in the AirTAC catalogue as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
This configuration uses a manual drain: condensate collects in the polycarbonate bowl and must be bled off periodically. If you prefer automatic or differential-pressure draining, those variants are available in the GFR series - ask us for the matching model code.
