The AirTAC GFR400C10JC2WT 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 GFR400C10JC2WT is a filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint, adjustable from 0.15 to 0.9 MPa (20 to 130 psi). This size 400 unit has a 3/8 in NPT port, the optional 5 um filter element (the finer of the two grades), the standard differential-pressure drain, and a round gauge reading in psi so you can set and monitor outlet pressure directly. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the polycarbonate bowl is the standard material for the 200 to 400 sizes.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of PT, G or NPT thread, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and square or round gauges in MPa, psi or bar scales. Flow for this model is published as a curve rather than a single rated figure; 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.

Filtered, regulated air for the clamp and gripper cylinders on a bottling or filling line, with the 5 um element protecting seals from fine particulate and the psi gauge letting the line technician verify setpoint at a glance.
Clean, stable air to sample-handling and lift actuators in an automated lab workstation, where the finer 5 um grade and a locally readable pressure gauge keep the pneumatic side predictable.
Supply air to the pop-up diverters and stop gates on a distribution conveyor, with the regulator holding a constant downstream pressure so gate timing does not drift as plant air fluctuates.
Size 400 with a 3/8 in NPT port sits in the upper-middle of the GFR range; step to 200, 300 or 600 (ports 1/8 to 1 in) to match the air your line consumes. The W code on this model selects the 5 um element instead of the 40 um standard, for finer particulate removal ahead of sensitive actuators or instruments. The differential-pressure drain is the catalogue default, with automatic (A) and manual (M) versions available if your duty calls for them. The fitted round gauge reads in psi; an embedded square gauge and MPa or bar scales are the alternatives. PT is the standard thread and G or NPT are order options - this code specifies NPT - and code J means no mounting bracket is included.
Flow for the GFR series is published as curves, not a single rated number, so we cannot quote a figure here. 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 GFR-series flow as curves rather than a single rated figure, so we do not quote a number on the page. Tell us your application and we will confirm the datasheet flow curve and check the sizing with you before you order.
The W code in GFR400C10JC2WT selects the optional 5 um filter grade, which removes finer particulate than the 40 um standard - useful ahead of precision actuators, valves or instruments. If your application does not need the finer grade, the 40 um standard version of the same unit is available.
