The AirTAC GFR400C10JC1TK 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 GFR400C10JC1TK is an AirTAC GFR400 filter regulator: one body that strips water and particulate from compressed air and holds the downstream pressure at your set point. This configuration has a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain that discharges collected condensate when the pressure drop across the element rises, a round external pressure gauge scaled in MPa, and a built-in check (reverse-flow) valve that stops downstream air pushing back through the unit. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, maximum inlet pressure is 1.0 MPa (145 psi), the bowl is polycarbonate (PC), and no mounting bracket is fitted.
This is a genuine AirTAC part, rated for -5 to 70 C (non-freezing) on compressed air only. The GFR range runs in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include 5 um filtration (code W), automatic or manual drains, the embedded square gauge or this round external gauge with MPa, psi or bar scales, G (BSPP) or NPT threads, and a mounting bracket. Flow is published as curves rather than a single rating, 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.

Position the GFR400C10JC1TK ahead of the directional valves and cylinders on a cartoning or case-packing line: the 40 um element removes water and pipe scale, the regulator holds a steady set point for consistent cylinder speed, and the check valve holds downstream pressure when the main supply is shut off at end of shift.
On a machining centre, feed pneumatic clamps, tool changers and chip-clearing jets through this 3/8 in filter regulator. Clean, regulated air protects the machine's valves from grit and moisture, and the MPa gauge gives the operator a clear set-point reference at the machine.
Install this unit as the air-preparation stage for diaphragm-actuated control valves on a water-treatment or chemical-dosing skid: filtered, pressure-stabilised air keeps the positioner and actuator working predictably, and the reverse-flow check valve protects the circuit from back-driven air.
Choose the size by port and flow demand: this unit is size 400 with a 3/8 in NPT port, and the GFR range steps through sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. Drain: this unit carries the differential-pressure drain (the default); automatic (code A) and manual (code M) versions are available. Filter grade: 40 um standard here, 5 um with code W. Gauge: this one is fitted with the round external gauge on the MPa scale; the embedded square gauge is the standard arrangement and psi or bar scales can be ordered. Thread: NPT here; PT is the standard catalogue thread and G (BSPP) is also an option. The K code adds a check valve, and J means no mounting bracket. Because flow is published as curves rather than a single rating, 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 GFR units as curves, not as a single rated number, so we do not quote a figure here. Send us your application details - port size, line pressure and the equipment you are feeding - and we will confirm the datasheet flow curve and check the sizing of the GFR400C10JC1TK for you on request.
The differential-pressure drain is the default and is what this unit carries: it discharges collected condensate when the pressure drop across the filter element rises. Choose automatic drain (code A) for unattended installations, or manual drain (code M) where you want to drain on demand - note that the manual-drain version also offers a wider 0.05-0.9 MPa setting range, against 0.15-0.9 MPa (20-130 psi) for this differential-pressure version.
