The AirTAC GFR400C15MJF2WG AirTAC Filter Regulator G1/2, 5 um 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 GFR400C15MJF2WG is a size 400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body, with no lubricator. This configuration is threaded G1/2 (1/2 in), carries the fine 5 um filter element instead of the standard 40 um, and uses a manual drain on the polycarbonate bowl, so an operator drains collected condensate by hand rather than relying on an automatic or differential-pressure drain. The standard regulator is fitted with an embedded square gauge reading in psi, and the set pressure is adjusted anywhere in the 0.05-0.9 MPa (7-130 psi) range. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). This version is supplied without a mounting bracket and without a reverse (check) valve.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and with options for drain type, filter grade, gauge style and scale, thread form (PT standard; G and NPT to order) and bracket. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application before ordering.

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 conditioning for a machining centre's pneumatic clamps and tool-change cylinders: the 5 um element protects fine control valves from particulate and water while the regulator holds a steady set pressure at the machine.
Filtered, regulated air for the cylinders on a carton former or case sealer, where the manual drain suits a line that is bled down at shift end and the psi gauge lets operators verify set pressure at a glance.
Conditioning the air feed to robotic grippers and pick-and-place actuators, where consistent regulated pressure keeps grip force repeatable and the fine 5 um grade guards the valve island upstream of the gripper.
Size 400 with a G1/2 port sits in the upper half of the GFR range; step up to size 600 or down to size 300 depending on the flow your line needs - we can check the published flow curves against your demand before you order. Because this unit has a manual drain, choose it where an operator is already present to bleed the bowl; pick the automatic or differential-pressure drain code instead for unattended installations. The 5 um element (code W) suits air that feeds sensitive valves and instruments; the standard 40 um element is enough for general actuator supply. The fitted square gauge here reads psi; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread and G or NPT are order options, and a bracket can be added if this J-coded, no-bracket version does not suit your panel layout.
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 no one flow number is quoted here. Tell us your inlet pressure, set pressure and required flow, and we will confirm the datasheet curve and check the sizing for your application on request.
The M in the code specifies a manual drain on the bowl: condensate is released by hand instead of automatically. Choose it where an operator is regularly at the machine; for unattended or hard-to-reach installations, select the automatic (A) or differential-pressure (blank) drain code instead.
