The AirTAC GFR400C10AJF2WG 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 AirTAC GFR400C10AJF2WG is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 400 unit is threaded G3/8, fitted with a 5 um filter element and an automatic drain that ejects collected condensate without anyone opening a valve. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), monitored on the embedded square gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), the size 400 bowl is polycarbonate, and the unit is supplied without a mounting bracket or reverse/check valve.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and order options including manual or differential-pressure drains, the 40 um standard element, external round gauges with MPa/psi/bar scales, and G or NPT threads in place of the PT standard. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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.

Clean, regulated air feeding the tool-change cylinders and clamping fixtures of a CNC machining center, where the 5 um element protects fine control valves from particulate and the automatic drain handles condensate between shifts.
A filter regulator mounted at the drop feeding the stoppers, pushers and diverters on a bottling or packaging conveyor, holding a steady setpoint so cylinder strokes stay consistent through the whole run.
The supply stage of a pneumatic control panel that branches air to direction control valves across an assembly line, with the square psi gauge giving operators a local reading of the branch pressure.
The decodable choices in this family are size and port, drain type, filter grade, gauge and thread. This unit sits at size 400 with a G3/8 port - a mid-range step; move to size 600 for larger ports or size 300 for smaller lines, and we can check the flow curves with you. Drain: this unit is automatic (code A), which suits lines that run unattended; manual (M) and the differential-pressure default are alternatives. Filter grade: 40 um is standard, while the 5 um element fitted here (code W) is the choice when downstream valves or instruments need finer air. Gauge: the embedded square gauge is standard with MPa, psi or bar scales, and an external round gauge is optional. Thread: PT is the AirTAC standard; G (this unit) and NPT are order options. Bracket code J means no bracket is included. Because flow is published as curves and not 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 rather than a single rated figure, so we do not quote a number on the page. Tell us the flow and pressure your line needs and we will confirm the sizing against the datasheet curves on request before you order.
This unit has an automatic drain, which ejects collected condensate by itself - useful on lines that run unattended or at light, intermittent load. Manual drain requires someone to open the drain regularly, and differential-pressure drain is the catalogue default. All three drain types are order options across the GFR family.
