The AirTAC GFR300C10MF2WT 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 GFR300C10MF2WT is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built with a 3/8 in NPT port, a 5 um filter element (the finer W grade, against the 40 um standard), a manual drain on the metal bowl, an embedded square gauge reading in psi, and the standard regulator type. Maximum inlet pressure is 1.0 MPa (145 psi), the regulated output adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator line is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um optional), gauge scales (MPa, psi or bar) and thread options (PT as standard, with G and NPT as order options). Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Feeding filtered, regulated air to the tool-clamp and chip-clearing circuits of a CNC machining centre, where the 5 um element helps protect close-tolerance pneumatic components from water and fine particulate.
Conditioning the air feeding diverters, pushers and sealing cylinders on a packaging conveyor line, with the regulator holding a steady set pressure so cycle behaviour stays repeatable through the shift.
Supplying regulated air to pneumatic quarter-turn valve actuators on a process skid, where the manual drain lets an operator bleed accumulated condensate during routine rounds and the psi gauge gives a local setpoint readout.
Start with size and port: the GFR300 step with a 3/8 in NPT port suits lines running at this connection size, and larger sizes (400, 600) move more air at the same pressure - match the size step to the demand of the downstream cylinders or valves. Then set the drain: this unit has a manual drain, which you bleed by hand, whereas automatic and differential-pressure drains remove condensate without operator attention. The 5 um element (code W) is the finer choice over the 40 um standard where downstream equipment needs cleaner air. The embedded square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread is NPT on this unit; PT is the catalogue standard and G is also offered. A bracket is included.
One honest note before ordering: AirTAC publishes filter-regulator flow as curves, not as a single rated number, so send us your application details and we will confirm the sizing against the datasheet before you commit.
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 filter-regulator flow as curves rather than as a single rated figure, so there is no one rated flow number we can quote for this unit. Send us your line pressure, set pressure and air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code sets a manual drain: condensate collected in the metal bowl is released by hand, which suits installations checked on a regular maintenance round; automatic and differential-pressure drains are available on other configurations if you want unattended condensate removal. The W in the code sets the 5 um filter element, a finer grade than the 40 um standard, chosen where downstream valves and actuators need cleaner air.
