The AirTAC GFR400C10C1TK 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 GFR400C10C1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 400 unit is fitted with a 3/8 in NPT port, the standard 40 um filter element and a differential-pressure drain that bleeds collected condensate automatically as flow passes through, so there is no manual draining routine in normal service. The outlet pressure is set with the adjusting knob across the 0.15-0.9 MPa (20-130 psi) range, an external round gauge on the MPa scale shows the set pressure at a glance, and the fitted reverse/check valve holds the downstream setting if the supply is interrupted. A mounting bracket is included, the polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of PT, G(BSPP) or NPT threads, 40 um or 5 um (code W) filtration, differential-pressure, automatic or manual drains, and gauge or no-gauge builds, so a matching unit can be specified for each drop in the plant. Flow is published as curves rather than a single rated figure; ask us and we will confirm the datasheet figures for this exact model before you order.

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.

Mounted at the drop feeding a pneumatic press cylinder, it strips water and swarf from the mill air line and holds a steady regulated pressure so the press stroke is repeatable shift after shift; the check valve keeps the setting if the main supply dips.
Installed ahead of the valve bank driving conveyor gate cylinders and diverters on a packaging line, it conditions the plant air and lets the line set the exact working pressure the actuators were designed for, with the MPa gauge giving operators a visible setpoint.
Fitted on the air preparation drop of a CNC cell, it cleans the compressed air feeding clamps and chip-blowing nozzles and regulates it to the clamp manufacturer's specified pressure, with the differential-pressure drain handling condensate without operator attention.
Start with the port step: this model is the size 400 body with a 3/8 in NPT thread; step up to size 600 or down to 300/200 where the pipe run or the flow demand of the machine calls for it - we will check the published flow curves against your consumption before you commit. Choose the drain to match the duty: differential-pressure (as fitted here) for unattended drops, automatic for intermittent-flow lines, or manual where an operator drains on a schedule. Pick the element grade: 40 um standard for general plant air, 5 um (code W) where finer protection is wanted downstream. Gauge scale is selectable (MPa, psi or bar) and the thread can be ordered as PT, G(BSPP) or NPT; a bracket is included on this build. Because flow is published as curves and not a single rating, send us the application details and we will confirm sizing from 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 GFR400 series as curves, not as a single rated number, so we do not quote a figure that is not on the datasheet. Send us your line pressure, working pressure and expected air consumption and we will confirm the flow from the datasheet for this exact model before you order.
The differential-pressure drain on this model bleeds condensate from the bowl automatically as air flows through, so the unit suits unattended positions. The GFR400 family is also available with an automatic drain for intermittent-flow duty or a manual drain where an operator drains on a schedule; note the regulation range differs by drain type, with manual-drain versions able to set down to 0.05 MPa (7 psi) versus 0.15 MPa (20 psi) on this differential-pressure build.
