The AirTAC GFR400C15JC2T AirTAC Filter Regulator NPT1/2, 40 um 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 GFR400C15JC2T is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This size 400 unit has a 1/2 in NPT port, standard 40 um filtration, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The C2 gauge code means an external round pressure gauge with a psi scale is fitted, and the J code means no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, thread options PT (standard), G and NPT, 40 um or 5 um (W) filtration, differential-pressure, automatic or manual drains, and embedded square or external round gauges with MPa, psi or bar scales. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Feeding clean, regulated air to the pneumatic cylinders and sealers on a carton or shrink-wrap packaging line, with the psi gauge giving operators a visible setpoint at the machine.
Conditioning the supply to clamps, tool-changers and air-powered fixtures on a CNC or machining cell, where the 40 um element keeps water and debris out of the control valves.
Regulating air to conveyor gate diverters, stoppers and pusher cylinders in a distribution centre, with the differential-pressure drain handling condensate without daily manual attention.
Sizing starts with the port step: this unit is size 400 with a 1/2 in NPT port, the right step when your line's air demand sits above what a 3/8 in unit comfortably handles; match the size to the flow curve rather than the port alone. Drain choice matters: the differential-pressure drain fitted here needs no operator attention, but a manual drain (M) suits intermittent duty and an automatic drain (A) suits continuously wet air. Filtration is the standard 40 um grade; specify the W code for 5 um when downstream valves or instruments need finer protection. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread here is NPT; PT is the standard thread and G is also orderable. No mounting bracket is included (J), so plan a bracket if you want panel fixing. Because flow is published as curves, not 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 state a rated l/min, m3/h or SCFM number. Ask us to confirm the datasheet and we will check the curve for the GFR400 at your operating pressure against your application before you order.
In this code, C is the external round gauge option and the scale digit 2 means it reads in psi. The catalogue also offers an embedded square gauge and MPa or bar scales, so if you prefer a different gauge style or scale, ask us to quote the matching GFR400 variant.
