The AirTAC GFR Filter Regulator GFR400C15JNW 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 GFR400C15JNW is a genuine AirTAC filter regulator: filtration and pressure regulation in a single 400-size body. This configuration combines a 1/2 inch PT port, a fine 5 um filter element (W grade) for cleaner downstream air, and a differential-pressure drain that vents collected condensate as differential pressure builds. No gauge is fitted (N) and no mounting bracket is included (J).
As a genuine AirTAC part, the GFR400 family covers sizes 200, 300, 400 and 600 with 40 um standard or 5 um (W) elements, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, an optional check valve (K), and PT, G or NPT threads. Maximum working pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so we will confirm 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.

Supplies clean, regulated air to spray nozzles and air-bearing fixtures on a finishing line, where the 5 um element limits fine particle carryover to the orifices.
Conditions the instrument-air feed to test benches and lab rigs that use pneumatic transducers and pilot controls, with one regulator setting held for the whole bench.
Feeds positioners and pilot-operated process valves on a process skid, where the fine 5 um filtration protects small internal passages and the differential-pressure drain handles line condensate.
Choose this code when you need the 400-size, 1/2 inch PT filter regulator with the fine 5 um (W) element but no local gauge - for example where pressure is read elsewhere on the panel. If your application only needs coarse protection of cylinders and directional valves, the standard 40 um element (blank position) is the more economical choice; reserve the 5 um grade for instruments, precision valves and pneumatic circuits sensitive to fine particles.
Drain options are differential-pressure (this model), automatic (A) or manual (M), with the regulation range 0.15-0.9 MPa (20-130 psi) on the differential-pressure and automatic versions and 0.05-0.9 MPa (7-130 psi) on the manual-drain version. Thread is PT as standard, with G (BSPP) and NPT as ordering options; a bracket and a check valve (K) are also orderable. Flow is published as curves, not a single rating, so ask us to confirm sizing against the datasheet 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.
There is no single rated flow figure to quote: AirTAC publishes G-series flow as characteristic curves against pressure. Share your inlet pressure, set pressure and required air consumption, and we will confirm the curve values from the datasheet for this model on request.
Use the 5 um W grade when the downstream equipment is sensitive to fine particles - instrumentation, precision valves, positioners, spray nozzles. The standard 40 um element is the default for general cylinder and valve protection. Both grades are available across the GFR400 series, so the choice is made in the code: W for 5 um, blank for 40 um.
