The AirTAC GFR400C10MC1WTK 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 AirTAC GFR400C10MC1WTK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 400 unit is threaded NPT3/8 (3/8 in), carries a 5 um filter element, a metal bowl with manual drain, an external round pressure gauge scaled in MPa, a fitted reverse (check) valve and a mounting bracket. The regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options across drain type, 40 um or 5 um filtration, gauge style and scale, PT/G/NPT threads and check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Point-of-use conditioning for a CNC cell: the 5 um element strips water and fine particulate before air reaches the tool-changer and clamping circuits, while the regulator holds a steady set pressure for repeatable clamping.
Feeding carton-sealing and case-packing cylinders on a packaging conveyor, where the manual drain lets an operator bleed accumulated condensate at shift start and the check valve holds downstream pressure if upstream supply dips.
A wall-mounted supply point for impact drivers and air ratchets in an assembly bay: filtered, regulated air at the workstation gauge, with the included bracket making the unit simple to fix beside the drop.
Within GFR400 the real, decodable choices are: port size (here NPT3/8) matched to your supply line; drain type - manual on this unit, with automatic or differential-pressure available; filter grade - this unit's 5 um element for finer particulate versus the standard 40 um; gauge - this configuration adds an external round gauge with MPa scale (an embedded square gauge is standard, and psi or bar scales can be ordered); thread - PT is the standard with G (BSPP) and NPT as catalogue options; plus the fitted reverse/check valve and included mounting bracket. Flow is published as curves, not a single rating, so 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 GFR400 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and full datasheet figures on request before you order.
A manual drain means an operator opens the drain periodically to release collected condensate, which suits attended stations with a regular maintenance routine. Note that with a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); automatic or differential-pressure drain versions are available for unattended installations.
