The AirTAC GFR400C15MJC2WGK 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 GFR400C15MJC2WGK is a size-400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a G1/2 (BSPP) port, a fine 5 um filter element (code W), a manual drain on the bowl, a round pressure gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. It ships without a mounting bracket (code J). Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing. The polycarbonate bowl suits this size in the G-series range.
This is a genuine AirTAC part from the GFR400 series. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, PT as standard thread and G or NPT as order options, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um fine filtration, and gauge styles and scales to match your panel. Flow is published as curves rather than a single rated figure, 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.

Feeding a bench-mounted pneumatic press or clamping fixture on a fabrication cell: the 5 um element protects the directional valve and cylinder seals from water and fine particles, the regulator holds a steady working pressure at the tool, and the check valve keeps the circuit from venting if the main supply drops.
Conditioning air for carton-forming and case-sealing actuators on a packaging line: filtered, regulated air at a set pressure keeps sealing cylinders repeatable through the shift, the manual drain lets an operator bleed accumulated condensate at start-up or end of shift, and the psi gauge gives a readable setpoint for the line's air station.
Supplying air to spray guns or coating applicators where clean, dry, pressure-stable air directly affects finish quality: the 5 um grade catches fine particulate before the gun, the regulator lets the operator dial in atomising pressure, and the round psi gauge makes the setting easy to verify between batches.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow your line needs; this unit is the 400 size with a 1/2 inch G-thread port. Choose the drain to suit access: manual (as here, with the wider 0.05-0.9 MPa adjustment band), automatic, or the differential-pressure default. Pick 40 um for general air prep or 5 um (this unit, code W) where downstream valves and instruments need finer protection. Gauge style and scale are decodable: embedded square or external round, in MPa, psi or bar - this code carries a round psi gauge. Thread is PT as standard with G and NPT as order options, and a bracket can be included or omitted (this unit has none, code J). Flow is published as curves, not a single rating, so send us your application details 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, not as a single rated number, so there is no one l/min, SCFM or Cv figure we can honestly quote. Tell us your line pressure, downstream demand and port size, and we will confirm the sizing against the datasheet on request before you order.
The M in the code selects a manual drain: an operator opens the drain at the base of the bowl to release collected condensate, which suits stations that are checked regularly. On a GFR with manual drain the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi); the differential-pressure and automatic drain versions adjust from 0.15 to 0.9 MPa (20-130 psi). If the installation is unattended, ask us about the automatic-drain variant.
