The AirTAC GFR40015MF2G AirTAC Filter Regulator, G1/2, Manual Drain 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 GFR40015MF2G is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the size 400 unit with a G1/2 (BSPP) port, a 40 um standard filter element, and a manual drain, so condensate is released by opening the bowl drain by hand as part of routine maintenance. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi) for manual-drain versions, and the embedded square gauge fitted here reads in psi so the set pressure can be checked at a glance. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits this size, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR400 series is one of four sizes (200/300/400/600) covering progressively larger ports and flow capacity, with options including a 5 um element (code W), automatic or differential-pressure drain instead of manual, gauge scales in MPa/psi/bar, an external round gauge, and PT or NPT thread in place of G. Flow is published as curves rather than a single rated figure, so we confirm the datasheet 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 0.05 - 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.

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.

Feeding filtered, regulated air to the clamping fixtures and tool-change cylinders on a machining centre, where a stable set pressure protects the clamping sequence.
Conditioning the air supply to carton-forming and sealing cylinders on a packaging line, with the psi gauge letting operators verify the set point during changeover.
Supplying diverters, stoppers and pusher cylinders along a conveyor system, where the 40 um element keeps scale and pipe debris out of the control valves.
Step up or down through the 200/300/400/600 sizes to match the port and flow capacity your line needs; this size 400 unit carries a G1/2 port. Choose the drain to suit maintenance practice: manual (this unit) is emptied by hand, automatic drains continuously, and differential-pressure drains on a pressure drop. The 40 um element fitted here is the standard grade; specify 5 um (code W) where finer filtration is required. The square gauge reads psi; MPa and bar scales and an external round gauge are available. Thread is G (BSPP) on this unit, with PT as the catalogue standard and NPT orderable. A mounting bracket is included.
Because flow is published as curves and not a single rated number, ask us to confirm sizing against your air consumption before ordering; we will check the datasheet with you.
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 GFR400 series as curves rather than a single rated figure, so we do not quote one number. Tell us your air consumption and working pressure and we will confirm the sizing from the datasheet on request before you order.
This unit has a manual drain: condensate collected in the polycarbonate bowl is released by opening the drain by hand as part of routine checks. Choose manual where maintenance visits are regular; automatic or differential-pressure drain versions are available if you need the bowl to discharge without operator action.
