The AirTAC GFR400C10MLC2WGK 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 GFR400C10MLC2WGK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, in size 400 with a G3/8 (BSPP) port. This configuration carries a 5 um filter element (the W grade, against the 40 um standard), a manual bowl drain, a low-pressure regulator type, a round pressure gauge reading in psi, a built-in reverse (check) valve, and a mounting bracket. Maximum working (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 filter-regulator family spans sizes 200, 300, 400 and 600, with ports from 1/8 in up to 1 in and options that include the 40 um standard or 5 um element, differential-pressure, automatic or manual draining, embedded square or external round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Feeds fixture and clamp actuators that must hold a reduced, stable pressure rather than full line pressure, with the 5 um element keeping fine particulate out of the clamp valves and the check valve holding the circuit if upstream supply dips.
Mounted at the machine inlet to remove water and particles from the shop air and regulate a low working pressure for the wrapper's low-pressure actuators, with the manual drain bled during scheduled changeover.
Installed on a prep panel in G3/8 to filter and regulate air before it splits to several downstream branches, with the psi gauge giving operators a local reading and the bracket securing the unit inside the panel.
Size 400 with a G3/8 port sits in the upper-middle of the GFR range; step up to size 600 or down to 300 depending on the flow your line needs - we can check the published flow curves against your demand on request. This unit is the low-pressure regulator type, chosen where the circuit holds a reduced pressure well below standard settings; the exact set range for the low-pressure type is not published, so confirm it with us. The 5 um element suits air prep where finer particulate removal matters; the 40 um standard element remains available if your duty is less demanding. Manual draining means an operator bleeds the bowl periodically - automatic or differential-pressure draining can be ordered instead. The round psi gauge is fitted here; an embedded square gauge scaled in MPa, psi or bar is the alternative. Thread is G (BSPP); PT is the standard thread and G or NPT are order options, stated as specification. A mounting bracket is included.
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 figure, so we do not quote one number. Send us your application details - line pressure and the air demand of your equipment - and we will confirm the sizing against the datasheet curves before you order.
The L code means the regulator in this GFR400 is the low-pressure type, intended for circuits held at reduced pressures; the exact set range for the low-pressure type is not published, so confirm it with us. Manual drain means the bowl is bled by hand at intervals - if you prefer unattended draining, the same family is available with automatic or differential-pressure draining.
