The AirTAC GFR400C10MJNTK AirTAC Filter Regulator, NPT3/8, Manual Drain 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 GFR400C10MJNTK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration has a 3/8 in NPT port, a manual-drain bowl, the standard 40 um filter element and an integrated reverse-flow (check) valve, and it is supplied without a gauge and without a mounting bracket. Outlet pressure is set anywhere in the 0.05-0.9 MPa (7-130 psi) adjustment range; 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 from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of G (BSPP), NPT or PT thread, automatic, manual or differential-pressure drains, an optional 5 um element and gauge options. Flow for this unit is published as a curve rather than a single rated figure, so ask us to confirm the datasheet and check the 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.

Clean, regulated air for the gripper, capper and filler cylinders on a bottling line, with the manual drain bled during scheduled changeover checks.
Conditioned air at a fixed setpoint for the tool changer and workpiece clamps on a machining centre, with the check valve holding the downstream circuit if supply pressure dips.
Filtered, regulated air for the diverter, stopper and pusher cylinders on a sorting conveyor, keeping moisture and debris out of the directional valves.
Size 400 with a 3/8 in NPT port suits circuits plumbed at 3/8 in; if your flow demand or piping differs, step up or down a size and we will confirm the flow curve against your requirement before you order. The manual drain needs an operator to bleed the bowl, so choose it where the unit is checked routinely; the automatic or differential-pressure drain variants suit unattended installations. The standard 40 um element protects most actuators and valves, while the W variant gives 5 um filtration for finer downstream needs. This unit is supplied without a gauge - a gauge with an MPa, psi or bar scale can be added if you want a local setpoint display - and without a mounting bracket. The thread here is NPT; PT is the standard and G (BSPP) is also an order option.
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.
Flow for the GFR400 is published as a curve, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet curve and check the sizing against your air demand before you order.
This model carries the N gauge code, so no gauge is fitted. Because it is a regulator, a gauge can be added - choose an embedded square gauge or an external round gauge with an MPa, psi or bar scale - so specify the gauge option when ordering if you want a local setpoint display.
