The AirTAC GFR400C15LJC2T AirTAC Filter Regulator NPT 1/2 in 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 GFR series combines filtration and pressure regulation in a single body: air passes a 40 um element that strips water and particulate, then feeds the built-in regulator that sets downstream pressure. This GFR400C15LJC2T is the size 400 unit with 1/2 in NPT ports, the low-pressure regulator type, a differential-pressure drain on the polycarbonate bowl, and an external round gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR line runs from size 200 to 600, with port sizes from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and standard or low-pressure regulator types. Rated flow is published only as curves rather than a single figure, so ask us to confirm sizing and any datasheet figure against 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.

Regulated low-pressure air for the clamp, flap-tuck and pusher cylinders on a packaging line, with the 40 um element keeping rust and pipe scale out of the valve seats.
Point-of-use filtration and low-pressure regulation for instrumentation and air-actuated sample valves on a laboratory or pilot plant skid fed from the shop air header.
Clean, low-pressure air for the divertor gates and stopper cylinders along a distribution conveyor, regulated locally instead of bleeding down the whole main line.
The real choices when specifying a GFR are: size and port (200/300/400/600, 1/8 to 1 in) stepped against the air demand of the circuit; drain type, where the differential-pressure drain is the default and automatic (A) or manual (M) are alternatives; filter grade, 40 um standard or 5 um with the W code for finer particulate; gauge, embedded square by default or an external round gauge scaled in MPa, psi or bar; thread, PT standard with G and NPT to order; bracket, included unless the J code omits it; and standard versus low-pressure regulator type. This unit is already fixed as size 400, NPT 1/2 in, 40 um, differential-pressure drain, low-pressure type, round psi gauge, no bracket. Because AirTAC publishes flow only as curves and the adjustment range of the low-pressure type is not a single published figure, send us your operating pressure and air demand and we will confirm suitability from 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 G-series flow only as characteristic curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, regulated setpoint and air demand, and we will confirm the flow from the datasheet on request before you order.
The embedded square gauge is the catalogue standard; the C2 code on this model specifies the optional external round gauge with a psi scale instead. Gauges can also be ordered in MPa or bar scales, or omitted entirely with the N code. Note that the regulator on this unit is the low-pressure type; its exact adjustment range is not a published figure, so we confirm it on request.
