The AirTAC GFR400C10MJC2WGK AirTAC Filter Regulator G3/8, 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 GFR400C10MJC2WGK is an AirTAC GFR400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a G3/8 port, a 5 um filter element (the finer of the two published grades), a manual drain for periodic bowl blow-down, a round pressure gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is removed. It is supplied without a mounting bracket. 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 working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 400 size; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR filter-regulator family spans four sizes (200, 300, 400, 600) with ports from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um fine filtration, embedded square or external round gauges in MPa, psi or bar scales, an optional low-pressure regulator type, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeds filtered, regulated air to the vacuum generators and small cylinders of a pick-and-place robot cell, with the 5 um element protecting fine pneumatic components and the check valve holding the circuit while the supply is isolated.
Supplies the flap-tuck and press cylinders of a carton sealer on a packaging line, keeping set pressure stable as boxes pass through and using the manual drain during scheduled line clean-downs.
Provides clean, regulated air to the clamping fixtures of a materials test bench, where the 5 um grade, psi-reading gauge and check valve let technicians set, read and hold clamp pressure between test runs.
Size drives the port and the flow envelope: 200, 300, 400 and 600 step up in both port diameter and capacity, so pick the size after checking the air demand of the circuit rather than the pipe alone. This unit is the 400 size with a G3/8 port. Drain choice matters in practice: manual drain (this unit) needs periodic operator blow-down and suits attended installations; automatic and differential-pressure drains suit unattended lines. Filtration grade is 40 um standard or 5 um (code W, fitted here) where finer particulate protection is needed. Gauges are embedded square as standard with an external round option, in MPa, psi or bar scales - this unit has a round psi gauge. Thread is PT as the AirTAC standard, with G and NPT as order options (this unit is G). Brackets are optional (not fitted here). Flow is published as curves, not a single rating, so 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 G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure and air demand and we will confirm the flow and sizing from the GFR400 datasheet on request before you order.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is released by operating the drain when needed, which suits attended machines and scheduled maintenance rounds. For unattended lines or high-condensate duty, the same GFR400 body is available with an automatic or differential-pressure drain - just specify the code variant.
