The AirTAC GFR400C15JF2WTK AirTAC Filter Regulator NPT1/2 5um 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 GFR400C15JF2WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 400 unit has a 1/2 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain, an embedded square gauge reading in psi, and a built-in reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate, and no mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and each size can be ordered with manual or automatic drain, a 40 um or 5 um element, MPa, psi or bar gauge scales, G, NPT or PT threads, and with or without a bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeding clean, regulated air to the tool-change clamps and pneumatic actuators on a CNC machining centre, where the 5 um element helps protect tight-tolerance valves downstream.
Regulating supply pressure to the diverters, sealers and clamp cylinders along a packaging conveyor so the downstream stations hold their setpoints consistently through the shift.
Point-of-use air preparation ahead of a robotic assembly cell, combining water and particulate removal with a stable regulated supply for grippers and press cylinders.
Choose the size and port against the air your line actually uses: size 400 with a 1/2 in port sits in the upper-middle range of the GFR family, which steps from 1/8 in (size 200) up to 1 in (size 600). The 5 um element (code W) is the right choice where finer particulate protection matters; the 40 um element is the standard grade. Drain options are differential-pressure (this unit), automatic, or manual, and the regulation range differs by drain type. Gauge scales are offered in MPa, psi and bar, and threads can be ordered in PT (the standard), G or NPT. Because flow is published as curves, not a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 datasheet flow figures so you can size the unit correctly.
The W code selects the 5 um filter grade instead of the 40 um standard, which suits applications needing finer particulate protection. The K code adds a reverse/check valve that helps hold downstream pressure if the upstream supply is interrupted. Both are catalogue options on the GFR family.
