The AirTAC GFR400C10C1T 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 GFR400C10C1T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 unit carries a 3/8 in NPT port, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the C1 suffix specifies an external round pressure gauge with an MPa scale fitted at the regulator. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), a mounting bracket is included, and no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. Within the series you can order a 5 um element (code W), automatic or manual drain instead of differential-pressure, square embedded or round external gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application 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.

Feeding clean, regulated air to the tool-change clamps and pneumatic actuators on a CNC machining centre, with the 40 um element catching water and swarf carried in the shop air line.
Conditioning the air that drives carton-forming and sealing cylinders on a packaging conveyor line, holding a steady set pressure so seal strokes stay repeatable through the shift.
Mounted at the drop of a bench assembly cell, filtering the plant ring main and setting a fixed working pressure for air screwdrivers, clamps and small press cylinders.
Start with the port and body size: GFR400 with a 3/8 in NPT port sits in the middle of the range, so match it to the line size and required air demand of the circuit. If finer filtration is needed downstream of sensitive components, order the 5 um element (code W) instead of the 40 um standard. Drain choice matters: differential-pressure (this unit) drains on pressure drop, automatic drains continuously, and manual drain requires periodic operator action - pick according to how often the installation is attended. Gauge scale (MPa, psi or bar) and the embedded square versus external round style are order options, as are the thread family (PT standard, G/BSPP or NPT) and the included mounting bracket. Flow for this series is published as curves, not a single rated number, so send us your application details and we will confirm sizing against 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 rather than a single rated figure, so no single rated flow number can be quoted. Tell us your inlet pressure and the air demand of your application and we will confirm the sizing from the datasheet on request.
The differential-pressure drain (the default on this model) releases collected condensate automatically when the pressure drop across the 40 um element rises, so it suits attended installations with steady demand. If the line runs unattended for long periods or flow varies widely, an automatic drain (code A) is the better choice; a manual drain (code M) suits intermittent, supervised use where an operator can bleed the bowl.
