The AirTAC GFR400C10ALF1T AirTAC Filter Regulator NPT3/8 Low-Pressure 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 GFR400C10ALF1T is a filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with no lubricator. This GFR400 unit is built for 3/8 in NPT ports, drains condensate automatically, and carries the standard 40 um filter element. The regulator is the low-pressure type, and the code confirms an embedded square gauge with an MPa scale, a mounting bracket, and no reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The 400-size bowl is polycarbonate (PC). Because this is the low-pressure (L) type, its adjustment band differs from the standard regulator; the exact range is not published in the material we hold, so ask us to confirm it against your set pressure.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and each size can be ordered with manual or automatic drain, a 5 um (W) element instead of the standard 40 um, gauge scales in psi or bar as well as MPa, G (BSPP) or NPT threads in place of the PT standard, and with or without a bracket. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm sizing and the full datasheet figures 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.

Filtered, regulated air at a low set pressure holds workpieces in CNC milling and drilling fixtures, with the automatic drain keeping condensate out of the clamp circuit.
Supplies clean, pressure-controlled air to the cylinders and grippers that close flaps and pack cartons along a packaging conveyor.
Feeds air knives and blow-off nozzles that clear dust and stray droplets from bottles or panels before labelling or inspection.
Choose the size by port and air demand: 200, 300, 400 and 600 step up in both port and flow, and this unit is already fixed at size 400 with a 3/8 in NPT port. Where a choice remains, decide the drain: automatic (as here) suits lines that run unattended, manual suits circuits checked on a schedule, and the differential-pressure default suits steady demand. The 40 um element is the standard grade; specify W for the 5 um option if downstream equipment needs finer filtration. Gauge scale can be MPa (as here), psi or bar, and threads can be ordered in G (BSPP) or NPT instead of the PT standard.
Because AirTAC publishes flow as curves rather than a single rated number, we do not quote a rated flow for this unit. Tell us your application and we will confirm sizing against the flow curve and the datasheet before you order.
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 a rated flow number. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the sizing against the flow curve and send the datasheet on request.
L marks the low-pressure regulator type, chosen for circuits that run below the standard regulator's range. The exact adjustment band for the low-pressure type is not published in our current material, so ask us to confirm it against your set pressure before ordering. Everything else in the code decodes as: 400 size, 3/8 in NPT ports, automatic drain, 40 um element, square MPa gauge, bracket included, no check valve.
