The AirTAC GFR400C10MLC2T AirTAC Filter Regulator NPT 3/8 in 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 GFR400C10MLC2T is an AirTAC GFR filter regulator: a 40 um filter element and a pressure regulator combined in one body, size 400, with a 3/8 in NPT port. This configuration has a manual drain, so collected water is released by hand, and a round pressure gauge reading in psi. The regulator is the low-pressure type, the bowl is polycarbonate (PC), a mounting bracket is included, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -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 in, and options including automatic or differential-pressure drains, a 5 um element (code W), square or round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and a no-bracket variant. AirTAC publishes flow as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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.

Feeds filtered, regulated air to carton-sealer and case-packer cylinders on a packaging line, with the manual drain letting an operator bleed accumulated water at shift start.
Sits ahead of a pneumatic press or clamping fixture on a machining cell, removing water and particulate from the incoming air and holding the working pressure the tooling was set up for.
Conditions the air supply to a laboratory automation skid, where the low-pressure type regulator and round psi gauge let technicians read and adjust setpoints directly in psi.
Work through the decodable choices in order. Size and port first: 200, 300, 400 and 600 step up in port and flow capacity, so match the 3/8 in NPT port here - or a neighbouring size - to your line's air demand. Then the drain: manual (this model, code M) suits attended installations, while automatic (A) and differential-pressure (blank) drains suit unattended duty. Filter grade is 40 um standard or 5 um with W. For the gauge, the embedded square gauge is standard and an external round gauge is optional, in MPa, psi or bar scales - this unit is fitted with a round psi gauge. Thread: PT is the standard, with G (BSPP) and NPT as catalogue options. Note that this is the low-pressure type regulator and its exact adjustment range is not published, so confirm it with us.
Then the honest routing: flow is published 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 GFR400 series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing against the datasheet before you order.
This unit is coded M for a manual drain: an operator opens the drain to expel water collected in the polycarbonate bowl. Automatic (A) and differential-pressure (blank) drains are catalogue options on the GFR family if you prefer unattended draining - ask us about the variant.
