The AirTAC GFR400C10JC3T AirTAC Filter Regulator 3/8 in NPT 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 GFR400C10JC3T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/8 in NPT port, the standard 40 um filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough. The outlet pressure is set with the standard-type adjusting range of 0.15-0.9 MPa (20-130 psi), and this unit is ordered with the external round gauge on a bar scale; the embedded square gauge remains the standard fitting style. The polycarbonate bowl suits non-freezing air from -5 to 70 C, and maximum working (inlet) pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, optional 5 um (code W) filtration, automatic, manual or differential-pressure drains, gauge scale choices, and G or NPT thread options. Flow figures for the GFR series are published as curves rather than a single rating, 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.

Clean, regulated air to fixture clamps and swing cylinders on a machining centre: the 40 um element keeps swarf-laden shop air out of the clamp circuit while the regulator holds a steady clamp pressure at the 3/8 in supply.
Feeding air cylinders, diverters and baggers along a packaging conveyor, where the differential-pressure drain handles condensate build-up through long shifts and the bar-scale round gauge lets operators check set pressure at a glance.
A filtered, regulated drop point off the main plant air header at an assembly bench: the filter regulator protects hand tools and small actuators from water and scale, with no bracket required for panel or manifold mounting by the installer.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this size 400 unit takes a 3/8 in port. Choose the drain to suit access: differential-pressure (as here, no operator input), automatic for continuous unattended condensate removal, or manual where an operator drains on a schedule. The standard element is 40 um; specify the W code for 5 um when finer pre-filtration matters. Gauge scale is selectable (MPa, psi or bar) and this unit carries the external round gauge on bar. Thread is NPT here; G (BSPP) is also an order option, with PT as the catalogue standard, and the J code means no mounting bracket is supplied.
Because GFR flow is published only as performance curves and not a single rated figure, 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 GFR performance as flow curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
This unit's differential-pressure drain bleeds condensate from the bowl automatically when the pressure drop across the 40 um element rises, with no operator input. An automatic drain suits unattended duty, and a manual drain (which also widens the regulation range to 0.05-0.9 MPa) suits stations an operator drains on a schedule. All three are order options in the GFR400 series.
