The AirTAC GFR400C15LJF2TK AirTAC Filter Regulator NPT1/2 Low-Pressure 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 GFR400C15LJF2TK is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. Compressed air passes a 40 um element that removes water and particulate, then a low-pressure type regulator holds the downstream setting. This configuration has 1/2 in NPT ports, a differential-pressure drain on the metal bowl, an embedded square gauge scaled in psi, and a built-in reverse (check) valve; it is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or manual drains, a 5 um element (code W), an external round gauge with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the standard PT, and a mounting bracket. Operating limits for this unit are 1.0 MPa (145 psi) maximum inlet pressure and -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet for 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.

Filtered, gently regulated air feeds the blow-off ring that dries cans before coding; the 40 um element strips water and particulate while the low-pressure regulator holds a soft, repeatable setting on a 1/2 in drop.
Shop air is filtered and regulated in one body before it reaches the clamp cylinders, keeping moisture and scale out of the valves at a steady modest pressure set on the psi gauge.
Low-pressure cylinders that steer bottles between lanes get clean, regulated air from a single GFR400 drop, with the differential-pressure drain keeping condensate out of the circuit.
Step up to the GFR400 when your circuit calls for a 1/2 in connection; the family steps 200/300/400/600 with ports from 1/8 to 1 in, and the right step is the one whose flow curve covers your consumption with margin - we can check that against the datasheet before you order. The decodable choices on this family are drain type (differential-pressure as here, automatic with code A, or manual with code M), filter grade (40 um standard, 5 um with W), gauge (embedded square as here, optional external round, scales MPa/psi/bar), thread (PT is the standard; G and NPT are order options), and bracket (this unit is supplied without one, code J). This is the low-pressure (L) regulator type; its exact set range is not published in the catalogue, so confirm your setpoint with us if your circuit sits below the standard range.
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 GFR series as curves, not as a single rated figure, so we do not quote a number on the page. Send us your operating pressure and air consumption and we will confirm sizing against the datasheet curves before you order.
It marks the low-pressure type of regulator. The catalogue does not publish an exact adjustment range for this version, so tell us your setpoint and we will verify it from the datasheet before you order.
