The AirTAC GFR400C10AJF2T AirTAC Filter Regulator NPT3/8 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 GFR400C10AJF2T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/8 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filtration element, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and an embedded square gauge scaled in psi. No mounting bracket is included with this variant. 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 is available in sizes 200, 300, 400 and 600 with a choice of ports, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, and MPa, psi or bar gauge scales. Flow data for the GFR series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Installed ahead of a CNC machine tool's pneumatic valve stack, the GFR400C10AJF2T strips water and chips of particulate from the shop air and holds the supply pressure steady at the level the machine builder specifies, with the automatic drain keeping condensate off the bowl in an unattended cell.
Mounted at the drop to a spray booth's air line, this filter regulator cleans moisture and dirt out of the atomising air and lets the booth operator dial in and read the delivery pressure on the psi-scaled square gauge, protecting finish quality from pressure wander.
Feeding the pneumatic cylinders and tape-head actuators on a carton sealing conveyor, the unit removes line condensate and particulate and regulates the pressure the cylinders see, with the automatic drain suiting a station that runs across multiple shifts without daily bowl attention.
Size 400 with a 3/8 in NPT port suits lines whose air demand sits in the upper mid-range of the GFR family; step up to size 600 or down to 300/200 depending on the flow your circuit needs. Drain choice matters: the automatic drain on this unit suits unattended or hard-to-reach installations, while manual and differential-pressure drains are available as alternatives. Filtration is 40 um standard on this model; specify the W variant if the 5 um grade is required. The square gauge here reads in psi; MPa and bar scales are also offered. PT is the standard thread and G or NPT are catalogue options to order, as is the mounting bracket (this variant is supplied without one). Flow for the GFR series is published as curves, not a single rating, 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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
This GFR400 configuration is fitted with an automatic drain, which discharges collected condensate from the bowl without operator attention - useful for inaccessible or continuously running installations. The GFR series is also available with a manual drain or the differential-pressure drain (the default); the drain choice also affects the regulator adjustment range quoted in the catalogue.
