The AirTAC GFR40015AF2T AirTAC Filter Regulator NPT1/2, Auto 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 automatic 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 GFR40015AF2T is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 400 unit with a 1/2 in NPT port, an automatic drain that empties collected condensate from the polycarbonate bowl without manual attention, a 40 um standard filter element, and the embedded square gauge with a psi scale so operators can read and set outlet pressure directly. The standard regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates in -5 to 70 C (non-freezing) conditions.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge scale, thread (PT standard, G or NPT as options) and bracket. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will 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 0.15 - 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.

Feed filtered, regulated air to a packaging machine's cylinders and actuators, with the automatic drain keeping condensate out of the bowl during continuous shifts and the psi gauge letting line staff verify set pressure at a glance.
Supply a pneumatic press or clamping fixture with clean air at a stable, repeatable outlet pressure, using the 40 um element to protect valve seals and the regulator to set the clamping force.
Serve a conveyor line's air jets and diverter cylinders from a single 1/2 in drop, with automatic condensate draining and the square psi gauge confirming the setting for blow-off and diverter functions.
Use the size/port step to match your line: this unit is size 400 with a 1/2 in NPT port, one step up from the 300 series and suited to larger air consumers. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Other decodable choices: drain type (this unit has an automatic drain; manual and differential-pressure drains are also available), filter grade (40 um standard here, 5 um with code W), gauge scale (this unit is the square gauge in psi; MPa and bar scales and an external round gauge are options), and thread (NPT here; PT is the standard and G is also available). 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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant flow/datasheet figures on request before you order.
The A in the code GFR40015AF2T means an automatic drain: condensate collected in the polycarbonate bowl is expelled without anyone opening it. Manual and differential-pressure drain versions exist in the same family if you prefer a different arrangement.
