The AirTAC GFR400C10MLC1T 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 AirTAC GFR400C10MLC1T is a GFR400-series filter regulator: a 400-size unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is tapped 3/8 in NPT, carries the standard 40 um filter element, and drains by hand - the polycarbonate bowl is opened manually to discharge collected condensate, so it suits installations checked as part of a routine walk-round. It is the low-pressure regulator type, and the round pressure gauge fitted here reads in MPa. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options across the family include automatic and differential-pressure drains, a 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air to the tool-change cylinders and clamping fixtures on a machining centre: the regulator holds the pressure setting the clamps were set up with, while the 40 um element catches pipe scale and condensed water upstream of the control valves.
Air preparation for the cylinder-and-valve banks that drive case erecting and sealing stations on a packaging conveyor, with the manual-drain bowl emptied as part of the scheduled line check.
A filter regulator ahead of the grip and clamp cylinders on a bottling line, keeping the regulator setting stable for the grippers while the 40 um element keeps rust and water out of the valves feeding them.
The meaningful choices in this family are size and port, drain type, filter grade, gauge and thread. Stepping from size 200 up to 600 increases both the port and the flow the unit can pass, so size against the air demand of the circuit rather than the pipe alone. Drains: manual (this unit) needs an operator to drain the bowl, while automatic and differential-pressure drains discharge condensate without that step. Filter grade is 40 um as standard; specify W for the 5 um element where finer particulate removal matters. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit carries the round MPa gauge. Threads follow the PT standard unless G (BSPP) or NPT is ordered, and a bracket is included. Because rated flow is published as curves rather than one number, send us your application details and we will confirm sizing and 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and the datasheet figures for this 400-size, 3/8 in unit on request.
The M in the code means the bowl is drained by hand: an operator opens the drain to discharge the water and dirt that have collected. If you would rather not schedule that task, the GFR400 size is also offered with an automatic or a differential-pressure drain; the low-pressure regulator type, 40 um element and round MPa gauge remain as ordered in this code.
