The AirTAC GFR30015MC2 AirTAC Filter Regulator PT1/2, 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 GFR30015MC2 is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in one body, sized for 1/2 in PT ports. This configuration carries a 40 um filter element, a manual-drain polycarbonate bowl, a standard regulator adjustable from 0.05 to 0.9 MPa (7-130 psi), and a round pressure gauge reading in psi. 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 series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with G or NPT threads, automatic or differential-pressure drains, a 5 um element (code W) and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

Filtered, regulated air ahead of solenoid valve manifolds on automated machinery, where the 1/2 in port feeds a main distribution run and the gauge shows the set pressure at a glance.
Conditioned air to air-operated clamping fixtures on CNC machining cells, removing water and particles upstream while holding a steady regulated pressure between cycles.
Point-of-use conditioning for packaging and labelling machines that need both clean air and a stable set pressure, with the manual drain emptied during scheduled line cleaning.
Choose the GFR300 size by port and flow demand: this unit steps up to 1/2 in PT for larger lines, while the 200 and 400 sizes cover smaller ports in the same family. The choices you can order on this series are: drain type (manual here; automatic or differential-pressure available), filter grade (40 um standard, 5 um with code W), gauge (round psi here; embedded square or other scales available), thread (PT standard; G and NPT to order) and bracket. Because flow is published as curves, not a single rating, ask us to confirm sizing against the datasheet 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 the GFR300 as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm sizing against the datasheet on request.
The M in the code specifies a manual-drain bowl: collected condensate is drained by hand when needed. Automatic and differential-pressure drain versions are available in the same series if you prefer unattended draining.
