The AirTAC GFR400C15JC2W AirTAC Filter Regulator 1/2 in, 5 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 AirTAC GFR400C15JC2W is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 400-size unit is fitted with a 1/2 in PT port, a 5 um filter element, a differential-pressure drain and a round pressure gauge reading in psi. The standard regulator covers 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 the 400 size, and no mounting bracket is included.
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 can be ordered with 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, G or NPT threads, and a bracket. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm the datasheet and flow 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.

Filtered, regulated air feeding the pneumatic clamps and tool-change cylinders on a machining centre, where the 5 um element helps protect directional valves from particles and water.
Steady downstream pressure for the stopper, pusher and gate cylinders that index cartons along a packaging conveyor, with the round psi gauge letting operators check the setting at a glance.
A single filter-regulator point supplying the air cylinders and air tools at an assembly-line workstation, holding the branch circuit at its set pressure between 0.15 and 0.9 MPa.
Choose the size and port step (200/300/400/600, 1/8 to 1 in) against the flow your line needs - the larger the size, the larger the port and flow capacity. At this 400 size you have already selected the 5 um element over the 40 um standard, a differential-pressure drain, and a round psi gauge; the alternative choices are an automatic or manual drain, a square gauge with an MPa, psi or bar scale, and G or NPT threads in place of the PT standard. A bracket can be added if panel or wall mounting is needed. Flow is published as curves, not a single rating, so 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow figures from the datasheet on request.
The standard GFR element is 40 um; the W option gives 5 um filtration, which suits circuits with sensitive valves or finer downstream equipment. This unit is supplied with the 5 um element, and the drain is the differential-pressure type, the default for the family.
