The AirTAC GFR400C15JNWTK AirTAC Filter Regulator NPT1/2 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 GFR400C15JNWTK is a size 400 filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in a single body. This configuration carries a 1/2 in NPT port, a fine 5 um filter element (the W grade, against the 40 um standard), a differential-pressure drain that bleeds collected condensate when the pressure drop across the element rises, a built-in reverse/check valve, and no gauge or mounting bracket fitted. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge options and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

Filter and regulate the shop-air feed feeding tool clamps, tool-change cylinders and coolant nozzles on a machining centre, with the 5 um element catching fine particulate before it reaches the machine's pneumatic circuit.
Condition the air feeding stoppers, pushers and diverters on a cartoning or palletising conveyor, holding a steady regulated pressure so cylinder stroke behaviour stays repeatable through the shift.
Place the unit upstream of a solenoid valve manifold on an automated assembly station, filtering water and 5 um particulate and regulating supply pressure before it reaches the valves and their actuators.
Sizing starts with the port and body size: this unit is the size 400 frame with a 1/2 in NPT port, the step to take when your line's flow demand sits above what a 3/8 in unit comfortably handles. Because the catalogue publishes flow as curves and not as one rated number, send us your application's flow and pressure targets and we will confirm the fit against the datasheet before you order. This unit already carries the 5 um W-grade element, the reverse/check valve, and the differential-pressure drain; the regulator type is standard with a 0.15-0.9 MPa (20-130 psi) setting range. A pressure gauge is not fitted (code N), and no mounting bracket is included - both are catalogue options on other variants if you need them. Thread is NPT here; PT is the standard thread and G (BSPP) is also available to 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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your application's flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
N is the no-gauge code: no pressure gauge is supplied with this variant, though gauges are a catalogue option on other GFR codes if you want a visual pressure reference. The W in the code is the filter grade: a 5 um element instead of the 40 um standard, for finer particulate removal upstream of sensitive components.
