The AirTAC GFR40015MF2TK AirTAC Filter Regulator NPT1/2 with Gauge 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR40015MF2TK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in one body. It filters compressed air down to 40 um and regulates downstream pressure across 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature range of -5 to 70 C (non-freezing). This configuration has a 1/2 in NPT port, a manual-drain polycarbonate bowl, a square pressure gauge reading in psi, and a built-in reverse (check) valve; a mounting bracket is included.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, plus a choice of automatic, manual or differential-pressure drains, 40 um or 5 um (W) filter grades, and gauge scale choices. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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 0.05 - 0.9 MPa (7 - 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.

|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Point-of-use clean-up and pressure setting on the air drop feeding a CNC machine's pneumatic tool clamps and chip-blow-off lines, with the check valve holding the set pressure if upstream supply dips.
Filtering and regulating the supply to cylinder-driven carton-forming and case-sealing stations on a packaging conveyor, where stable downstream pressure keeps stroke timing consistent.
Conditioning shop air at the inlet of a paint booth's spray-gun manifold, removing water and pipe scale at 40 um and setting the gun supply pressure, with manual draining at each shift.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a 1/2 in port, and larger sizes carry larger ports and more flow. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Other real, decodable choices: drain type (this unit is manual drain; automatic and differential-pressure drains are available in the series), filter grade (40 um standard, 5 um with code W), gauge scale (MPa, psi or bar; square embedded as standard, external round optional), thread (PT standard, G or NPT to order), and bracket. This unit also carries a reverse (check) valve, code K.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and full datasheet figures on request before you order.
The M in the code means the polycarbonate bowl is drained by hand: someone opens the drain at the bottom of the bowl to let collected water out. Automatic and differential-pressure drain options exist in the series if you would rather not rely on manual draining, and the manual-drain version has a wider regulator adjustment range starting at 0.05 MPa (7 psi).
