The AirTAC GFR400C15JC1T 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 GFR400C15JC1T 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 1/2 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element rises, and a round pressure gauge with an MPa scale. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The size 400 bowl is polycarbonate (PC), and this unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, threads, drain types, 40 um or 5 um (W) filtration, gauge styles and scales, and bracket options. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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.

Cleaned and pressure-regulated air feeding the tool-change cylinders, clamps and solenoid valves on a machining centre, with the MPa gauge giving operators a local set-point readout.
A filtered, regulated supply for the pick-and-place and divert cylinders on a carton packaging line, where the differential-pressure drain keeps condensate off the actuators without daily manual draining.
A drop-leg filter regulator at a production cell, taking air off the main header and delivering it to air tools and workholding fixtures at the pressure the cell was set up for.
Size the unit by the flow your line needs: step up through sizes 200, 300, 400 and 600 as port size and air demand grow - this size 400 unit with its 1/2 in NPT port suits higher-demand drops. Choose the drain to match access: differential-pressure (this unit) needs no daily attention, automatic (A) drains continuously, and manual (M) suits attended installations. Filtration is 40 um as fitted here; specify W for the 5 um element where finer protection is needed. Gauges come as the embedded square type or an external round gauge (this unit) with MPa, psi or bar scales. Thread is PT as the catalogue standard, with G (BSPP) and NPT as order options - this unit is NPT. Brackets are optional; this configuration omits one. 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 the GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the relevant flow and datasheet figures for this exact configuration on request.
PT is the catalogue standard thread for the GFR series, with G (BSPP) and NPT offered as order options. This unit is specified with NPT, so it suits 1/2 in NPT piping common in North American installations. If your plant runs PT or G threads, ask us for the matching catalogue code.
