The AirTAC GFR400C10ALC2W AirTAC Filter Regulator 3/8" PT, 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 GFR400C10ALC2W is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the 400 size with PT3/8 ports (PT thread standard; G and NPT are order options), a 5 um filter element (code W, against the 40 um standard), an automatic drain that expels collected condensate without manual attention, and the low-pressure regulator type for applications set below standard working ranges. It carries a round external gauge scaled in psi, includes a mounting bracket, and has no reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with a choice of port, drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale, and thread form. 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.

Point-of-use air preparation for a packaging machine's cylinder and actuator circuits: the 5 um element protects directional valves from water and fine particulate, the automatic drain keeps condensate off the shop floor without operator rounds, and the low-pressure regulator holds a gentle working pressure for delicate sealing and forming motions.
Conditioning the air feed to lab benches, analytical instruments and pneumatic sample-handling rigs, where the 5 um grade and stable low-pressure regulation protect sensitive components, the psi-scaled round gauge gives operators a familiar readout, and the automatic drain suits equipment that runs unattended.
Supplying regulated air to clamping fixtures and light assembly tooling that must not be over-pressed: the low-pressure regulator type is chosen for circuits set below standard working pressures, the 5 um element keeps spool valves and check valves clean, and the included bracket allows tidy panel-side mounting at the cell.
Start with the port step: the 400 size here is PT3/8, and the family steps through 1/8" to 1" across sizes 200-600, so match the size to the air demand of the circuit rather than upsizing blindly - and let us confirm the flow curve against your consumption. Drain type is a real choice: differential-pressure (the default) drains only when the pressure drop warrants it, automatic drains continuously without attention, and manual requires operator action; this unit is automatic, which suits unmanned or intermittently attended installations. The 5 um element (code W) is the finer option against the 40 um standard - choose it where downstream valves and instruments are sensitive to finer particulate. Gauge options are the embedded square gauge or an external round gauge, in MPa, psi or bar scales; this unit has a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options, and a mounting bracket is included. Note this is the low-pressure regulator type (code L); its exact adjustment range is not published in the material we hold, so confirm it with us. Because flow is published as curves and not a single rating, ask us to verify 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 flow for the GFR family as performance curves rather than a single rated figure, so there is no one rated flow number we can honestly quote. Tell us your operating pressure and air consumption and we will confirm the flow curve and correct sizing from the datasheet on request before you order.
The A in the code GFR400C10ALC2W selects the automatic drain, which expels collected condensate from the bowl without operator attention. The family also offers a differential-pressure drain (the default, which drains when the pressure drop warrants it) and a manual drain (code M, drained by hand). Automatic suits unmanned or intermittently attended installations; manual suits supervised points where you want full control over discharge.
