The AirTAC GFR300C10MF2T AirTAC Filter Regulator 3/8 in NPT 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 AirTAC GFR300C10MF2T is a size 300 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration carries a 3/8 in NPT port, a 40 um standard filter element, a manual drain on the bowl, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and a mounting bracket is included. No reverse/check valve is fitted in this version.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, a 5 um optional element (code W), gauge scale options, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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.

Feeding clamp cylinders on a machine-tool press: the 40 um element strips water and chips carried in the shop air line, while the regulator holds a steady clamp pressure read locally on the psi square gauge.
Conditioning air to diverters, sealers and gate cylinders on a packaging conveyor, where the manual drain suits a line that is bled down at shift start and the 3/8 in NPT port matches the machine's drop.
A point-of-use filter regulator at an assembly bench, giving each cell its own set pressure independent of the header line, with the included bracket mounting the unit at the operator's panel.
Size 300 with a 3/8 in port suits lines whose air demand sits in the middle of the GFR range; step up to size 400 or 600, or down to 200, according to the flow your circuit needs. Drain choice matters: this unit has a manual drain, which suits attended installations where an operator bleeds the bowl on a routine; choose automatic or differential-pressure drain for unattended duty. The 40 um element is the standard grade; specify the 5 um W option only where finer particulate removal is required. The fitted square gauge reads in psi; MPa and bar scales are also available. PT is the standard thread, with G (BSPP) and NPT as catalogue options - this unit is ordered in NPT. A mounting bracket is included.
Flow for this family is published as curves, not as a single rated figure, so send us your application details and we will confirm sizing against the datasheet 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 there is no one rated flow number we can quote. Send us your application's air demand and line pressure and we will confirm sizing against the datasheet on request.
The M in the code specifies a manual drain on the bowl: collected water is released by hand rather than automatically. It suits attended installations bled on a routine schedule; for unattended duty, the automatic (A) or differential-pressure (blank) drain versions are the catalogue alternatives.
