The AirTAC AirTAC GFR400C10MC2W Filter Regulator 3/8in PT 5um 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 GFR400C10MC2W is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 400-size unit is built with a 3/8in PT port, a manual-drain bowl, a 5um filter element (the W grade, finer than the 40um standard) and a round gauge reading in psi. The standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits operating temperatures of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. GFR400 sits in the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8in to 1in, a choice of differential-pressure, automatic or manual drains, 40um or 5um elements, square or round gauges in MPa, psi or bar scales, G or NPT thread options, and a mounting bracket (included here). Flow is published as curves rather than a single rating, 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.

Filtered, regulated air to pneumatic clamps on a machining centre, with the 5um element protecting fine clamp valves and the psi gauge set to the fixture's clamp pressure.
Supplying regulated air to pick-and-place and sealing cylinders on a packaging conveyor, with the manual drain opened during shift-change bowl checks.
Regulated air to a pneumatic control valve actuator on a process skid, where the 5um element keeps pilot solenoids clean and the round gauge shows the set pressure in psi.
Choose the size and port against the flow your line needs: the GFR400 steps up from the 200/300 sizes with a 3/8in PT port, and the larger 600 size carries more flow again. Pick the drain to match the installation: manual drain (this unit) suits attended sites where an operator drains the bowl on schedule, while automatic and differential-pressure drains suit unattended runs. Select the 5um element when downstream equipment needs finer filtration than the 40um standard, and set the gauge scale to your plant convention (this unit reads psi; MPa and bar are available). Thread is PT as standard with G (BSPP) and NPT as order options, and a mounting bracket is included. Because AirTAC publishes flow as curves rather than a single rating, send us your flow and pressure requirements 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 GFR400 as performance curves rather than a single rated figure, so there is no one number we can quote. Send us your required flow and working pressure and we will confirm the figures from the datasheet on request.
This unit has a manual-drain bowl: an operator opens the drain to remove collected water, which suits attended installations on a regular maintenance round. For unattended lines, the same GFR400 body is available with automatic or differential-pressure drains. This configuration also carries the 5um (W) element instead of the 40um standard.
