The AirTAC GFR400C10JNWTK AirTAC Filter Regulator NPT3/8, 5 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 GFR400C10JNWTK is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 5 um element (the fine grade, in place of the standard 40 um) and regulates downstream pressure within the 0.15-0.9 MPa (20-130 psi) adjustment range. The differential-pressure drain bleeds accumulated condensate automatically as the pressure differential across the element rises, and a reverse/check valve is fitted to hold the downstream setting if upstream supply is interrupted. Porting is 3/8 in NPT thread, and no pressure gauge is fitted with this configuration.
This is a genuine AirTAC part in the GFR400 size class of the G-series air-treatment range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, drain types, filter grades and gauge choices to suit the application. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Feeds the pneumatic cylinders on a case-sealing machine with filtered, regulated air, with the 5 um element protecting valve seals and the check valve holding the setting through brief supply dips.
Supplies the air cylinders that raise diverters and stop gates on a packaging conveyor, keeping water and fine debris out of the directional valves while holding a stable working pressure.
Prepares air for a laboratory automation cell's pneumatic grippers and pick-and-place modules, where the fine 5 um grade and automatic differential drain reduce servicing interruptions.
Choose the GFR400 size when your line calls for 3/8 in porting; larger sizes carry larger ports and more flow capacity. This unit pairs the fine 5 um filter grade (W code) with a differential-pressure drain, which suits setups that want condensate handled without manual attention; a manual-drain variant exists where dry ambient conditions or a service routine make that preferable. Note that this configuration ships without a gauge (N code) and without a mounting bracket (J code), while the fitted check valve (K) protects the regulated downstream pressure. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also an order option. Because flow for this series is published only as curves, not a single rated figure, 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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and required flow, and we will confirm sizing against the datasheet curves on request before you order.
Yes. The N code in GFR400C10JNWTK means no pressure gauge is supplied with this configuration. G-series regulator-equipped units accept an embedded square gauge or an optional external round gauge, with MPa, psi or bar scales, ordered as a catalogue option.
