The AirTAC GFR40015F1T 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 PT1/2" 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 GFR40015F1T is a size-400 filter regulator that combines two jobs in one body: it removes water and particulate from compressed air with its standard 40 um element, and it regulates downstream pressure across a 0.15-0.9 MPa (20-130 psi) setting range. This configuration has a 1/2 in NPT port, a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element is high enough, and an embedded square gauge scaled in MPa so the set pressure is visible at a glance. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR400 series. The GFR line spans sizes 200, 300, 400 and 600 with a choice of port sizes, G/NPT thread options, manual or automatic drains in place of the differential-pressure default, a 5 um filter element (code W), different gauge scales, and a reverse/check valve option. We confirm flow and datasheet figures on request, because flow for this series is published as curves rather than a single rated number.

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 machining centre, with the 40 um element catching pipe scale and water before it reaches the valves.
Regulated air for the cylinders and grippers on a carton-forming and sealing line, where the square MPa gauge lets the line technician verify set pressure without extra instrumentation.
A filtered and regulated branch drop feeding air tools and fixture clamps at an assembly bench, with the differential-pressure drain handling condensate collected at the point of use.
Start with the size and port: the 400 frame with a 1/2 in NPT port sits in the upper-middle of the GFR range, so step up to 600 or down to 300 depending on the air demand of the circuit - ask us to confirm sizing against the published flow curves before ordering, since no single rated flow figure applies. Next choose the drain: this unit uses the differential-pressure default, but a manual drain (code M) or fully automatic drain (code A) can be specified. The 40 um element is standard here; specify the W code if the application needs the 5 um grade. The embedded square gauge on this model is scaled in MPa, with psi and bar scales available as options. Thread is NPT on this unit; PT is the standard thread and G (BSPP) is also a catalogue option. A mounting bracket is included, and a reverse/check valve (code K) can be added if the circuit needs one.
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 GFR-series flow as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application's air demand and we will confirm the sizing against the datasheet curves on request before you order.
This configuration uses the differential-pressure drain, which is the GFR default: condensate is discharged automatically when the pressure difference across the filter element builds high enough, with no operator action needed. If you prefer a manual drain (code M) or a fully automatic drain (code A), those are catalogue options on the same series - just ask us to quote the alternative code.
