The AirTAC GFR400C10JC2WG 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 GFR400C10JC2WG is an AirTAC GFR400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size 400 unit is specified with a G3/8 (BSPP) port, 5 um filtration element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential is sufficient, and an external round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C (non-freezing). No mounting bracket is included with this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and each size can be ordered with manual or automatic drain, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series 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.

Point-of-use conditioning on a machining centre's compressed-air drop: the 5 um element protects solenoid valves and cylinders from particulate and water carryover while the regulator holds a steady set pressure to the machine's actuation circuits.
Feeding pneumatic cylinders and grippers on a packaging or case-erecting conveyor line, where the filter-regulator keeps contaminant-laden shop air out of the actuators and holds the working pressure the line was set up for.
Installed on a branch line off a factory ring main to condition and regulate air for a work cell, with the differential-pressure drain handling condensate drop-out and the psi gauge giving operators a local reading of the regulated pressure.
Choose the size 400 / G3/8 step when your line flow sits above what a 300-size body handles; the catalogue publishes flow as curves per size, so have us check the curve against your demand rather than guessing. This unit is already configured with the finer 5 um element (W code) - select 40 um instead if your application tolerates coarser filtration and you want the standard grade. Drain is differential-pressure here; choose automatic (A) for unattended condensate removal or manual (M) where you drain on a schedule. The round psi gauge is fitted; square gauges and MPa or bar scales are orderable alternatives. Thread is G (BSPP) - PT is the catalogue standard and NPT is available as an order option. This configuration has no mounting bracket; bracketed versions exist. Before ordering, send us your flow and pressure requirements so we can confirm sizing from the datasheet.
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 figure we can quote. Send us your required flow and working pressure and we will confirm the sizing from the datasheet curves before you order.
The W code in the model sets the finer 5 um filtration grade instead of the standard 40 um element - useful where downstream valves and instruments are sensitive to finer particles. The blank drain position means the differential-pressure drain: condensate is discharged automatically when the pressure differential across the drain is sufficient, with no manual draining routine. If you prefer a fully automatic float drain or a manual drain, those are orderable variants of the same unit.
