The AirTAC GFR400C15MC1T 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 GFR400C15MC1T is an AirTAC GFR400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body, sized 400 with a 1/2 in NPT port. This configuration carries the standard 40 um filter element, a manual drain on the bowl, and a fitted round pressure gauge with an MPa scale. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with manual drain, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on size 400 is PC (polycarbonate).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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 tool-change clamps and pneumatic actuators on a CNC machining centre, with the 1/2 in port matching the main drop to the machine.
Filtered, pressure-set air for the diverters, pushers and sealing heads on a carton packaging line, where the manual drain lets maintenance bleed the bowl during scheduled changeovers.
Air preparation at the panel feeding gripper and clamp circuits in a robotic handling cell, keeping water and swarf out of the valves while holding a set working pressure.
Size 400 with a 1/2 in port sits in the upper half of the GFR range; step up to size 600 or down to 300/200 depending on the flow your line needs, and confirm the step against the published flow curves before ordering. Drain choice matters: manual drain (this unit) means an operator bleeds the bowl on a schedule; automatic drain suits unattended installations; the differential-pressure default drains on a set pressure drop. Filtration is 40 um standard - choose the 5 um element (code W) only where downstream valves or cylinders demand finer air. The fitted round gauge reads in MPa; psi and bar scales are order options, and an embedded square gauge is the standard alternative. Thread here is NPT; PT is the AirTAC standard and G (BSPP) is also available to order. A mounting bracket is included with this unit. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 GFR400 flow as curves rather than a single rated figure, so no single number would be honest. Send us your line pressure and required downstream flow and we will confirm the sizing from the datasheet curves on request.
This configuration is coded for a manual drain: an operator opens the drain to bleed collected water from the bowl. If the installation runs unattended, the same GFR400 body is available with an automatic drain, or with the differential-pressure drain that is the range default - just order the matching drain code.
