The AirTAC AirTAC GFR400C10JC2T Filter Regulator NPT3/8 40 um 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 GFR400C10JC2T is an AirTAC GFR-series filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This size 400 unit has a 3/8 in NPT port, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The fitted round gauge reads in psi, so the set pressure can be checked at a glance, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). 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 is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um (code W) filtration, differential-pressure, automatic or manual drains, and gauge or no-gauge variants. Flow figures are published as curves rather than a single rating, 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.

Feeds clean, regulated air to the tool-change clamps and pneumatic gates on a CNC machining centre, with the psi gauge letting the setter verify set pressure during changeover.
Prepares air for the cylinders and diverters on a carton packaging line, where the 40 um element protects seals from water and debris and the differential drain keeps condensate moving without operator attention.
Serves as the point-of-use filter regulator for a robotic pick-and-place cell, holding a stable supply pressure to the grippers while the round gauge gives maintenance staff a quick visual check.
Choose the size and port step against the air your application actually consumes: size 400 with a 3/8 in port sits in the middle of the GFR range, and the next step up or down changes both the port and the flow capability. For this unit the drain is differential-pressure, which suits installations that see steady, cyclic demand; if the line runs at low, constant flow, an automatic (code A) or manual (code M) drain is the better choice. The 40 um element is the standard grade for general plant air; specify 5 um (code W) only where finer protection is required. The round psi gauge fitted here is one of the gauge and scale options (embedded square gauge standard, external round gauge optional, MPa/psi/bar scales); PT is the standard thread with G and NPT as order options, and a mounting bracket can be ordered where piping support is needed.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow 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, not as a single rated figure, so we do not quote a flow number for this unit. Tell us your application and required flow and we will confirm the datasheet and check that size 400 with a 3/8 in NPT port is correctly sized before you order.
In the code GFR400C10JC2T, the C2 position selects the external round gauge with a psi scale, and the J position specifies no mounting bracket. If you would prefer the embedded square gauge, a different scale (MPa or bar), or a bracket for panel or wall mounting, those are decodable options on the same GFR400 size - just ask and we will confirm the right code.
