The AirTAC GFR400C10MLC2 AirTAC Low-Pressure Filter Regulator 3/8 PT 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 GFR400C10MLC2 is an AirTAC GFR400 filter regulator: water and particulate removal plus pressure regulation combined in a single body. The 40 um element cleans the compressed air supply, and the low-pressure regulator sets downstream pressure for circuits that run below normal line pressure. This configuration is the 400 size with a PT3/8 (3/8 in) port, manual drain, a fitted round pressure gauge reading in psi, the included mounting bracket, and no reverse/check valve.
It is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drain, an optional 5 um element (code W) in place of the standard 40 um, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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 0.15 - 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.

On CNC fixtures that hold aluminium or fully finished surfaces, the low-pressure regulator sets a gentle clamp pressure below full line pressure so soft parts are not marked, while the 40 um element keeps debris out of the clamp cylinders.
Light-duty cylinders on carton sealers, labellers and case packers run at reduced pressure; this unit filters the supply and lets the line set the working pressure the packaging cycle needs, with the psi gauge giving operators a reading they can check at a glance.
Spray guns and air-assisted applicators call for a low, fixed supply setting; this filter regulator cleans the air going to the booth and lets the finisher set the gun supply pressure, with manual drain suiting a booth that is blown down at the end of each shift.
Size the unit by port and expected flow: the 400 size with its PT3/8 port sits mid-range in the GFR family, and stepping up or down changes both the port and the flow capacity. This unit is the low-pressure type (L), intended for circuits set below normal line pressure; the exact adjustment span of the L variant is not published, so confirm it with us before ordering. The manual drain (M) means condensate is drained by hand, which suits supervised installations; automatic and differential-pressure drains are available where routine draining cannot be relied on. The 40 um element is standard and a 5 um element (code W) can be ordered for finer filtration. The fitted round gauge reads in psi; square gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G and NPT available to order, and the mounting bracket is included. Because flow is published as curves rather than a single rating, 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 GFR400 as curves, not as a single rated figure, so there is no one number we can honestly quote. Send us your application - port size, downstream demand and working pressure - and we will confirm the flow and the full datasheet figures on request before you order.
L marks the low-pressure regulator variant, intended for circuits set below normal line pressure; its exact adjustment span is not published, so confirm it with us. M marks a manual drain: condensate collected in the bowl is drained by hand rather than automatically, which suits installations that are checked routinely. If you need automatic draining, ask about the A-coded version.
