The AirTAC GFR400C15MF1TK 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 GFR400C15MF1TK is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built around a 1/2 inch NPT port, with a manual drain bowl in polycarbonate (size 400 bowls are PC; only size 600 uses aluminium alloy). The standard 40 um filter element handles general-purpose air preparation, the manual drain lets an operator bleed collected condensate on a chosen schedule, and the embedded square MPa gauge shows outlet pressure at a glance. A reverse/check valve is fitted, a mounting bracket is included, and the standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include automatic or differential-pressure drains, a 5 um element (code W), G (BSPP) or NPT threads in place of the PT standard, alternative gauge scales, and a low-pressure regulator type. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds clean, pressure-controlled air to the tool-clamp and actuation circuits of a CNC machining centre, with the 1/2 inch port suiting a machine-level drop fed from the shop main. The MPa gauge lets setters verify clamp pressure at the machine, and the manual drain suits a cell opened for daily checks.
Conditions and regulates air for the cylinders and air-driven diverters on a carton packaging or palletising conveyor, where stable regulated pressure keeps case-forming and sealing strokes consistent shift after shift. The check valve helps hold the downstream setting if upstream supply dips.
Serves as the point-of-use filter regulator on an assembly or fabrication shop air drop, removing pipeline water and scale before hand tools, air cylinders and clamps, while the bracket mounts the unit neatly at the bench regulator position for easy gauge reading and drain access.
Start with the size and port: GFR400 carries a 1/2 inch port, and the 200/300/400/600 size steps exist so you can match the body to the flow your line needs - if your demand sits near the top of a smaller size, step up rather than undersize. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet before you order. This unit has a manual drain, which suits attended installations where an operator can bleed the bowl regularly; for unattended or hard-to-reach positions, ask about the automatic or differential-pressure drain versions of the same size. The 40 um element fitted here is the standard grade; specify the 5 um W option if downstream equipment needs finer filtration. The square MPa gauge is fitted as standard, and psi or bar scales plus an external round gauge are available. Thread is NPT on this model; PT is the catalogue standard and G (BSPP) is an order option. A mounting bracket is included.
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 one number. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow and sizing from the datasheet for this 1/2 inch size-400 unit before you order.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is released by operating the drain when chosen, which suits attended installations on a regular maintenance round. The same GFR400 body is also available with an automatic drain (code A) or the differential-pressure drain (blank) - ask us to quote the variant.
