The AirTAC GFR30015MNT 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 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 GFR300-15MNT is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is ordered with NPT1/2 ports, a manual drain on the bowl, a standard 40 um filter element, and no gauge fitted - so connect your own pressure indicator downstream if visual pressure reference is needed. With the manual drain, the regulation range is 0.05-0.9 MPa (7-130 psi), and the maximum inlet pressure is 1.0 MPa (145 psi). The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR family, which spans 200, 300, 400 and 600 sizes with port options from 1/8" to 1". Within the series you can choose automatic, manual or differential-pressure drains, a 5 um element (code W), gauge and scale options, G or NPT threads, and low-pressure or reverse-valve variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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.

Clean, regulated air to the cylinder circuit of a bench or C-frame press, where the operator sets working pressure once per job and drains the bowl during shift checks.
Point-of-use conditioning for carton sealers and wrap stations, filtering line water and particulate before it reaches valves and actuators on the machine frame.
Mounted at a branch off the main header, it gives a work cell its own filtered and regulated supply so upstream pressure swings do not reach the tools below.
Step up or down through the 200/300/400/600 sizes against the flow your line needs - the 300 size carries 1/2" ports, and the published flow curves (not a single rating) are the honest way to size it, so send us your demand and we will confirm against the datasheet. On this unit the choices are already fixed: manual drain (simplest service routine, and it widens the regulation range to 0.05-0.9 MPa), 40 um standard filtration, no gauge, NPT thread, and the included bracket. If you would prefer hands-off condensate removal, the automatic-drain variant of the same series is available; if finer filtration is needed, specify the 5 um W element; and if you want a pressure readout, order a gauge-equipped version with MPa, psi or bar scale rather than adding one downstream.
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 number, so we will not quote a figure that is not in the specification. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing against the datasheet before you order.
The M in the code selects a manual drain - you bleed condensate by hand during routine checks, and it widens the regulation range to 0.05-0.9 MPa (7-130 psi). The N selects no gauge, so no pressure indicator is supplied; if you want a readout, the same series is available with an embedded square gauge in MPa, psi or bar scale.
