The AirTAC GFR40015JC3TK AirTAC Filter Regulator NPT1/2 with Gauge 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 PT1/2" 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 GFR40015JC3TK is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 400 unit is threaded NPT1/2 (1/2 in), carries the standard 40 um filter element, drains condensate by differential pressure, and is fitted with an external round pressure gauge scaled in bar. A reverse/check valve (code K) is fitted, and 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 working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits clean-air points of use; size 600 units in this family use an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads as order options. Flow for this series is published as curves rather than a single rated figure, 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.

Clean, regulated air feeding the cylinders that divert, stop and index cartons on a packaging conveyor line, with the gauge letting operators verify set pressure at a glance.
Filtered and regulated supply to the clamp cylinders on a CNC fixture, holding consistent clamping force while the 40 um element keeps wear particles and water out of the valves.
A point-of-use filter regulator ahead of the actuator bank on a bottling or filling line, with the reverse/check valve holding the downstream setting if upstream supply dips.
Size 400 with a 1/2 in port sits in the upper half of the GFR range, so step up or down between 200, 300, 400 and 600 according to the air demand of the circuit rather than the pipe alone. This unit drains by differential pressure, which suits lines that run steadily; choose automatic drain (code A) for unattended duty or manual drain (code M) where an operator checks the bowl. The standard element is 40 um; specify 5 um (code W) if downstream valves or cylinders need finer protection. The fitted round gauge reads in bar; square-gauge and MPa or psi scales are available, and G (BSPP) or NPT threads can be ordered instead of the PT standard. A mounting bracket is not included with this code (J). Because flow in this series is published as curves and not as 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so no single flow number can be quoted honestly. Tell us your application and we will confirm the datasheet flow figures for this size 400, 1/2 in unit on request before you order.
K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply drops. This unit has no drain letter, which is the differential-pressure drain: condensate is discharged automatically when the pressure differential across it rises, with no operator action needed. Automatic (A) and manual (M) drains are available as alternative codes.
