The AirTAC GFR30015MF2T AirTAC Filter Regulator NPT1/2, 40 um 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 AirTAC GFR30015MF2T is a size 300 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1/2 in NPT port, a manual drain on the PC bowl, a 40 um standard filter element, an embedded square gauge reading in psi, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR300 series. The GFR line is offered in sizes 200, 300, 400 and 600, with a choice of drain type, a 5 um (code W) filter element option, gauge scales in MPa, psi or bar, and PT, G or NPT thread options. Flow is published as curves rather than a single rating, so we confirm datasheet and sizing figures 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.

Fitted at the machine drop on an assembly line, it cleans water and scale out of the plant air supply and holds a set pressure to the cylinders and directional valves that index the fixtures.
Mounted at the inlet of a packaging conveyor's pneumatic panel, it protects the diverters, pushers and stop cylinders from condensate and keeps their operating pressure steady through the shift.
Installed on the supply to a lab or test-bench rig, it dries and filters the air feeding instruments and small actuators and lets the operator dial in a stable, repeatable pressure for each test.
Step up or down through the 200/300/400/600 sizes to match the port and flow your line needs; this size 300 unit carries a 1/2 in port. Drain choice matters: manual drain suits points where an operator can bleed the bowl on a schedule, while automatic and differential-pressure drains suit unattended installations - note that the manual-drain version carries the wider 0.05-0.9 MPa regulation range. Choose the 40 um standard element or the 5 um (W) element where finer filtration is required, pick the gauge scale (MPa, psi or bar), and order PT, G or NPT thread to suit your piping. A bracket is included with this unit.
Flow for this family is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
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 this series as curves, not as a single rated figure, so there is no one rated-flow number we can quote. We can confirm the datasheet and flow curves for the GFR300 at 1/2 in on request - just ask and we will size it against your application before you order.
A manual drain means an operator bleeds the PC bowl on a schedule, which suits attended points of use. It also carries the wider regulation range of 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain versions are regulated from 0.15-0.9 MPa (20-130 psi). If you prefer unattended drainage, ask for the A (automatic) or default differential-pressure code.
