The AirTAC GFR300C10MLF1WT AirTAC Filter Regulator NPT3/8 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 GFR300C10MLF1WT is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. This configuration decodes to a 3/8 in NPT port, a manual drain on the bowl, a fine 5 um filter element (the W grade, against the 40 um standard), the low-pressure regulator type, a square pressure gauge fitted and scaled in MPa, a mounting bracket included, and no reverse/check valve. The metal bowl collects water and particulate stripped from the compressed air, and the manual drain is opened by hand to expel accumulated condensate.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with matching port sizes, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge and thread options (PT standard; G and NPT to order), and standard or low-pressure regulator types. Flow is published as curves rather than a single rating, so we 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.

Feeding filtered, regulated air to the pick-and-place and sealing cylinders on a packaging line, where the 5 um element protects directional valves from particulate and the regulator holds a steady supply pressure.
Supplying pneumatic clamps on a machining fixture that must be held at a reduced pressure to avoid distorting the workpiece, using the low-pressure regulator type to set and hold the lower setting.
Conditioning the air feeding grippers and small actuators on an assembly station, with the manual drain bled at shift start and the MPa gauge giving operators a visible line-pressure check.
Size the unit by the port and flow step: this size 300 unit carries a 3/8 in port, one step up from 1/4 in and one below 1/2 in, so match it to the air consumption of the circuit it feeds. Choose the drain to suit access: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl periodically; automatic and differential-pressure drains are available elsewhere in the family for unattended duty. The 5 um element (code W) is the finer choice over the 40 um standard where downstream valves and instruments need cleaner air. The fitted square gauge reads in MPa; psi and bar scales and an external round gauge are options. Thread is NPT here; PT is the catalogue standard and G is also orderable. A bracket is included.
Because flow is published as curves and not a single rated figure, ask us to confirm sizing and the low-pressure adjustment range against your application 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing data from the datasheet on request before you order.
The M in the code specifies a manual drain: condensate collects in the metal bowl and is released by hand, which suits installations that are checked regularly. The GFR family also offers automatic and differential-pressure drain options if you need the bowl to discharge without operator attention.
