The AirTAC GFR30015MC2WGK AirTAC Filter Regulator G1/2 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR30015MC2WGK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built around a G1/2 (1/2 in) port with G thread, carries the 5 um (W) filter element instead of the standard 40 um, and has a manual-drain polycarbonate bowl that is opened by hand to expel collected condensate. A round pressure gauge scaled in psi is fitted, a reverse/check valve (code K) is fitted, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, 40 um standard or 5 um optional filtration, manual, automatic or differential-pressure drains, and gauges scaled in MPa, psi or bar; only the size 600 bowl is aluminium alloy, while 200/300/400 bowls are polycarbonate. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

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.

A point-of-use filter regulator feeding clamps and pneumatic actuators on a CNC machining centre, where the 5 um element helps keep particulate and water out of downstream valves and the regulator is set to the machine's supply pressure.
Filtered, regulated air for the pick-and-place cylinders and product diverters on a packaging conveyor, with the psi gauge read at a glance and the manual drain emptied during routine shift checks.
A regulated take-off on a maintenance workshop air ring main, where the unit feeds hand tools and blow guns and technicians set the line pressure on the round psi gauge.
Size 300 with a G1/2 port is the mid-range step in the GFR line; step down to size 200 or up to 400/600 as your port size and flow demand - and ask us to confirm sizing against the flow curve before ordering, because AirTAC publishes flow as curves rather than one rated figure. This unit is already specified with the choices that matter: the 5 um (W) element for finer particulate capture than the standard 40 um, a manual drain instead of automatic or differential-pressure, a round gauge scaled in psi, and a reverse/check valve. With the manual drain, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi); automatic and differential-pressure drain versions adjust from 0.15 to 0.9 MPa (20-130 psi). This unit carries G thread; PT is the standard thread and NPT is also a catalogue option to order. A mounting bracket is included.
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 GFR300 flow as performance curves rather than a single rated figure, so no flow number is quoted here. Tell us your application and we will confirm the flow and datasheet figures for the GFR300 at the G1/2 port on request.
The M in the code specifies a manual drain: the bowl is emptied by hand, which suits lines checked on a regular shift routine. With the manual drain, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi); automatic and differential-pressure drain versions adjust from 0.15 to 0.9 MPa (20-130 psi).
