The AirTAC GFR400C15MC1TK AirTAC Filter Regulator NPT1/2 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 GFR400C15MC1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single size-400 body with a 1/2 in NPT port. This configuration carries a manual drain bowl, a 40 um standard filter element, a round pressure gauge with MPa scale, a built-in reverse (check) valve, and the included mounting bracket. With manual drainage, the regulated outlet range is 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus drain, filter-grade (40 um or 5 um), gauge-scale and reverse-valve choices. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Installed at the drop of a plant air main feeding a carton-forming and sealing line, it cleans water and scale from the compressed air and holds a steady regulated pressure to the packaging machine's cylinders and valves.
Mounted ahead of the solenoid valves on a conveyor system's pneumatic take-offs, it removes condensate and pipe debris and lets maintenance set one stable working pressure for the drive and gate cylinders.
Built into the air-preparation panel of an OEM machine or test rig, the single-body filter regulator saves panel space at the 1/2 in main feed, while the check valve holds downstream settings if supply pressure dips.
Size 400 with a 1/2 in port sits in the upper half of the GFR range; step up or down (200/300/400/600) to match the pipe size and flow demand of the line. This unit is specified with a manual drain, which suits installations where an operator can bleed the bowl on a routine; choose automatic or differential-pressure drainage where the unit is inaccessible. The 40 um element is the standard grade; specify 5 um (code W) only where finer particulate removal is required. The round gauge here reads in MPa; psi and bar scales are also available, and an embedded square gauge is the standard alternative. Thread is NPT on this code, with PT as the catalogue standard and G also orderable. A mounting bracket is included.
Before ordering, ask us to confirm sizing: flow for this series is published as curves, not a single rated number, so we check the datasheet against your application rather than quoting a figure.
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 here. Tell us your line pressure, working pressure and air demand, and we will confirm the sizing from the datasheet on request before you order.
Manual drainage means an operator opens the bowl drain to discharge collected water, which suits units mounted where they are easy to reach; automatic and differential-pressure drains are available on other codes. This unit also carries a 40 um element, a round MPa-scale gauge, a built-in reverse (check) valve, and the mounting bracket is included.
