The AirTAC GFR400C15JNT 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 GFR400C15JNT is an AirTAC GFR400 filter regulator: water and particulate removal plus downstream pressure regulation combined in a single body. This configuration is built around a 1/2 in NPT port with the standard 40 um filter element and the family's default differential-pressure drain. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, a maximum inlet pressure of 1.0 MPa (145 psi), and a -5 to 70 C (non-freezing) operating window. The bowl on this size 400 unit is polycarbonate (PC). No gauge is fitted (code N), and no mounting bracket or reverse/check valve is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with optional 5 um filtration (code W), automatic or manual drain alternatives, gauge choices with MPa, psi or bar scales, PT, G or NPT thread options, and bracket options. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm flow and datasheet details 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.

Point-of-use preparation for a CNC cell: the unit strips condensed water and particulate from the shop air line and holds a steady downstream setting for clamps, tool-change cylinders and pneumatic fixtures.
On a bottling or cartoning line, this filter regulator cleans and regulates the air feeding conveyor stopper cylinders, case erectors and sealing heads, keeping water carryover and pressure swings away from the actuators.
At a spray-booth air drop, filtered and regulated air feeds the paint pot and spray-gun supply line, helping keep moisture and debris out of the finishing process.
Within the GFR range, the size step (200 / 300 / 400 / 600) sets the port and the flow capacity, so pick the size whose published flow curve covers your downstream demand - this unit is the 400 size with a 1/2 in NPT port. Drain choice matters: this unit carries the default differential-pressure drain, while code A gives automatic and code M gives manual draining. Filtration is 40 um as standard; specify W for the 5 um element where finer particle removal is needed. Units with a regulator can be ordered with an embedded square gauge or an external round gauge in MPa (1), psi (2) or bar (3) scales - this configuration is ordered without a gauge (code N). Thread is PT as the catalogue standard, with G and NPT as order options; this unit is ordered in NPT. Brackets are optional (code J omits it).
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure and downstream demand 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 GFR400 series as curves rather than a single rated figure, so we do not quote a number on the product page. Send us your inlet pressure, downstream demand and allowable pressure drop, and we will confirm sizing from the datasheet before you order.
Yes. GFR400 units can be ordered with an embedded square gauge or an external round gauge (code C or F), with the scale set to MPa (1), psi (2) or bar (3). Ask for the gauge option code when ordering, or fit a suitable gauge separately.
