The AirTAC GFR400C10LC2K AirTAC Filter Regulator 3/8 in 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 GFR400C10LC2K is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure, in this low-pressure type configuration. This unit is built for a 3/8 in PT port, includes a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element rises, and carries a round pressure gauge scaled in psi so the set pressure can be read at a glance. A reverse/check valve is fitted, and the mounting bracket is included.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices, 40 um or 5 um filtration, gauge and thread options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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, pressure-controlled air to the tool-clamp and pallet-change circuits of a machining centre, where the low-pressure setting and psi readout suit the machine's actuator supply.
Conditioning the air that drives conveyor stop-gate and pusher cylinders on a packaging line, with the check valve holding the set pressure against upstream dips.
Serving as the point-of-use filter regulator on a drop leg in a textile mill, removing pipeline water and particulate before it reaches loom and winding-machine air circuits.
Size and port set the capacity: the 400 size with its 3/8 in PT connection suits lines where larger ports are run, but the right step depends on the flow your circuit actually needs. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order. Other decodable choices on this family: drain type (differential-pressure as fitted here, or automatic or manual), filter grade (40 um standard, 5 um with code W), gauge style and scale (this unit has the round gauge in psi; the embedded square gauge is standard and MPa/psi/bar scales are available), thread (PT is standard on this code; G and NPT are order options), bracket, and the low-pressure regulator type selected here. If your line runs below standard regulator ranges, the low-pressure type is the relevant variant - confirm the exact range with us.
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 this family as curves, not as a single rated number, so we do not quote a figure. Send us your application details and we will confirm the flow and full datasheet figures for the GFR400 at 3/8 in PT before you order.
K means a reverse/check valve is fitted, which holds the downstream setting against upstream pressure loss. The C2 in the code means the round external gauge is fitted and scaled in psi; the embedded square gauge is the standard option and MPa, psi or bar scales can be ordered.
