The AirTAC GFR300C15MC2TK AirTAC Filter Regulator NPT1/2 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 See datasheet ports, a differential-pressure 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 GFR300C15MC2TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit is supplied with a 1/2 in NPT port, a 40 um standard filter element, a manual drain bowl, a round pressure gauge with psi scale, a built-in check valve and a mounting bracket. With manual drainage, the bowl is emptied by hand, which suits installations that are checked as part of a routine maintenance walk. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and the maximum working (inlet) pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of thread (PT standard; G and NPT to order), drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, and check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Installed at the air drop feeding a production cell, it cleans water and debris from the header supply and holds a set pressure for the cell's actuators, with the manual drain emptied during scheduled rounds.
Mounted ahead of the cylinders and air bearings on a packaged conveyor line, it conditions the supply and keeps drive pressure steady as multiple stations cycle, with the check valve holding the setting if feed pressure dips.
Fitted on the supply to a laboratory or QA test bench, it delivers filtered, regulated air to fixtures and gauges, with the psi-scaled round gauge giving a clear local reading for test set-ups.
Size 300 with a 1/2 in port sits in the middle of the GFR range; step up or down through sizes 200/400/600 as your line's flow demand changes, and match the port to your piping (NPT here, with PT standard and G available to order). The 40 um element is the standard grade for general plant air; choose the 5 um (W) option where downstream equipment needs finer filtration. The manual drain suits attended installations, while automatic and differential-pressure drains are available on other variants in the family. The round psi gauge is fitted here; embedded square gauges and MPa/bar scales are the other catalogue choices, and the fitted check valve holds downstream pressure if the upstream supply is lost.
Flow for this family is published as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet and sizing before you order.
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 rather than a single rated figure, so we do not state a number here. Tell us your application and we will confirm the datasheet and check the sizing against your required flow before you order.
The M in the code means the bowl is drained by hand, which suits installations visited during routine maintenance. The GFR family is also available with automatic or differential-pressure drains on other variants - ask us if you would prefer one of those for an unattended location.
