The AirTAC GFR400C15AC2WGK 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 GFR400C15AC2WGK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single 400-size body with a 1/2 inch (G1/2) port. This configuration carries the 5 um filter element (code W) for finer filtration than the standard 40 um grade, an automatic drain that expels collected condensate without operator attention, a round pressure gauge reading in psi, and a reverse/check valve. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with this automatic-drain version, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this 400-size unit is polycarbonate.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and gauge or no-gauge variants. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

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 filtered, regulated air to the clamping and ram cylinders of a mechanical press cell, where the 5 um element protects directional valves from particulate and the regulator holds a steady working pressure shift to shift.
Conditioning the air feeding gripper actuators on a robotic handling cell, with the automatic drain keeping condensate out of the circuit during unattended runs and the check valve holding the set pressure upstream of disturbances.
Supplying regulated air to the pusher and sealing cylinders of a carton-sealing conveyor station, where stable downstream pressure keeps stroke timing consistent and the psi gauge lets operators verify setpoint at a glance.
Start with the port and size: this unit steps up to the 400 frame with a 1/2 inch G1/2 connection, the right choice when your line needs more capacity than a 300-size unit; match the frame to the flow your circuit demands. Choose the drain to suit access: automatic drain (fitted here) suits unmanned or enclosed installations, manual drain suits attended stations, and the differential-pressure default is the catalogue standard. Choose the 5 um element (this code) when downstream valves or instruments need finer air than the 40 um standard grade. The round gauge here reads psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is G (BSPP) on this code; PT is the standard thread and NPT is an order option. A mounting bracket is included.
One honest note before you order: AirTAC publishes flow for this series as curves, not as a single rated number, so send us your application details and we will confirm the sizing against the datasheet before you commit.
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 there is no one rated-flow number we can honestly quote. Send us your application details and we will confirm the flow and sizing figures from the datasheet on request.
The A in the code specifies an automatic drain, which expels collected condensate on its own - useful where the unit is mounted in a hard-to-reach spot or runs unattended. The catalogue also offers manual drain and a differential-pressure drain as the default; note that the regulator adjustment range differs by drain type: 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual drain.
