The AirTAC GFR400C10MJF2WG 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 GFR400C10MJF2WG is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 unit is supplied with a G3/8 (3/8 in) G-thread port, a manual drain on the polycarbonate bowl, a 5 um filter element (the W code selects 5 um over the 40 um standard), and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and the operating 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 ports from 1/8 to 1 inch, and options across the series include automatic, manual or differential-pressure drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and mounting brackets. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

On a CNC machine tool, this filter regulator cleans the shop air feeding pneumatic workholding clamps and holds a steady regulated pressure so clamping force stays consistent part after part.
In a distribution center, this unit filters and regulates the air supply to pop-up diverter and pusher cylinders on a sortation conveyor, keeping water and debris out of the valve bank.
On a laboratory or pilot-line test rig, this filter regulator conditions the compressed air feeding actuated test fixtures and valves, with the 5 um element protecting sensitive pilot components.
Size and port: 400 is the larger mid-size step in the GFR range, and the 10 code gives a 3/8 in port here in G (BSPP) thread; PT is the standard thread form and NPT is also an order option. Drain: the M code specifies a manual drain, so condensate is drained by hand from the bowl - automatic and differential-pressure drains are available elsewhere in the series. Filtration: the W code selects the 5 um element over the 40 um standard. Gauge: the embedded square gauge with psi scale is fitted; an external round gauge and MPa or bar scales are options. The J code means no mounting bracket is included. Flow for this series is published as curves, not a single rated figure, so 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 here. Send us your application details and we will confirm the datasheet flow curve and sizing for this unit before you order.
The M code in GFR400C10MJF2WG specifies a manual drain, so condensate collected in the bowl is drained by hand. The GFR series is also available with automatic or differential-pressure drains - tell us which variant you need and we will confirm it from the catalogue.
