The AirTAC GFR300C10MLC2WT 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 AirTAC GFR300C10MLC2WT is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with NPT3/8 ports, a 5 um filter element (code W), a manual drain on the metal bowl, the low-pressure regulator type, and a round external pressure gauge with a psi scale. A mounting bracket is included and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale, PT/G/NPT thread variants and bracket choice. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow figures for your operating conditions 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 a bench pneumatic press or clamping fixture that runs below standard line pressure: the 5 um element protects the valve train while the low-pressure regulator holds the reduced setting and the psi gauge shows it at a glance.
Point-of-use conditioning for a carton-sealing or wrapping machine, where filtered, regulated air at reduced pressure drives the cylinders and the round psi gauge lets operators verify the setting during changeover.
Supplying clean, regulated low-pressure air to laboratory automation or test rigs, where the 5 um grade and manual drain suit supervised environments and the psi scale matches US-built instruments.
Size and port set the capacity step: this unit is size 300 with NPT3/8 ports; the larger 400 and 600 sizes carry more flow if your demand grows. The 5 um element (W code) suits applications needing finer particulate removal than the 40 um standard. Drain is manual on this code - automatic and differential-pressure drains are available on other codes if you cannot schedule bowl draining. The gauge is a round external type with a psi scale; the embedded square gauge and MPa/bar scales are alternatives. Thread is NPT here; PT (the standard) and G are order options. A mounting bracket is included. AirTAC publishes flow as curves, not a single rating, so ask us to confirm sizing 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 rather than a single rated figure, so no rated number is quoted here. Send us your operating pressure and air demand and we will confirm the flow and datasheet figures for this exact model on request.
The M in the code specifies a manual drain: the metal bowl is drained by hand, which suits installations checked on a routine. This is also the low-pressure (L) regulator type; its exact adjustment range is not published in the standard tables, so we confirm it on request. If hand draining is impractical, automatic and differential-pressure drain codes are available in the same family.
