The AirTAC GFR400C10AJF2W AirTAC Filter Regulator PT3/8, 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 AirTAC GFR400C10AJF2W is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 5 um filter element (the finer of the two catalogue grades), an automatic drain that ejects collected condensate from the bowl without manual attention, an embedded square pressure gauge reading in psi, and a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range. The port is PT 3/8 in, and no mounting bracket is included with this variant.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with a choice of ports, PT (standard), G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge scale options, and a reverse/check valve where required. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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 clean, regulated air to tool-clamp and pallet-change actuators on a machining centre, where the 5 um element protects close-tolerance valves from particulate and the automatic drain keeps condensate out of the circuit.
Supplying regulated air to conveyor-mounted diverters, pushers and bag-sealing cylinders on a packaging line, with the square psi gauge giving operators a local setpoint readout at the machine.
Serving as the filter-regulator stage for a robotic assembly cell, conditioning the air before it reaches gripppers and pick-and-place cylinders while the automatic drain handles moisture during multi-shift running.
Size 400 with a 3/8 in PT port sits in the upper-middle of the GFR range, so step up or down by port size against the air demand of the circuit. This unit already carries the finer 5 um element (code W) instead of the 40 um standard, an automatic drain instead of manual or differential-pressure, and a square gauge scaled in psi; PT is the standard thread, with G and NPT available as order options. No bracket is fitted, so plan your mounting accordingly.
Because flow is published as curves rather than a single rating, 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a rated flow figure. Send us your application details and we will confirm the flow data from the datasheet on request before you order.
The W code in the model sets the finer 5 um filtration grade instead of the 40 um standard, and the A code sets an automatic drain that discharges condensate from the bowl by itself. Both are catalogue options on the GFR400; manual-drain and 40 um variants are available if your application does not need them.
