The AirTAC GFR400C10MC1WT 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 GFR400C10MC1WT is a size 400 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration carries a 3/8 in NPT port, a 5 um filter element (the W grade, finer than the 40 um standard), a manual drain on the bowl, and an external round pressure gauge scaled in MPa. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with the manual-drain version, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C in non-freezing conditions. The polycarbonate bowl is fitted with a mounting bracket, and no reverse/check valve is included in this code.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch. Across the family you can choose drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale (embedded square or external round; MPa, psi or bar), thread (PT standard, with G and NPT as order options), and bracket or no bracket. Flow figures for this series are published as curves rather than a single rating, so we confirm the datasheet and sizing on request.

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.

Cleaning and regulating the shop-air feed to tool changers, clamps and pneumatic actuators on a machining centre, with the 5 um element protecting fine spool valves and the round gauge letting the setter dial in the circuit pressure.
Conditioning air for carton-forming and case-sealing cylinders on a packaging conveyor, where the combined filter-regulator keeps one compact station instead of a separate filter and regulator, and the manual drain is emptied during scheduled changeovers.
Supplying cleaned, regulated air to grippers and weld-gun clamping cylinders in a robotic welding cell, with the bracket-mounted unit fixed to the cell panel and the MPa-scaled gauge giving operators a visible setpoint for consistent clamping force.
Start with the port step: this unit is the size 400 body with a 3/8 in NPT port; if your line needs more or less flow capacity, the GFR family steps through 1/8, 1/4, 3/8, 1/2, 3/4 and 1 inch across sizes 200 to 600. The W code here selects the 5 um element - choose it when downstream valves, cylinders or instruments need finer filtration than the 40 um standard; the manual drain (M) means an operator opens the drain periodically rather than relying on automatic or differential-pressure action. The round gauge in this code reads in MPa; psi and bar scales are available, and an embedded square gauge is the alternative style. Thread is NPT on this unit; PT is the standard thread and G (BSPP) can be ordered. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so send us your application details and we will confirm the datasheet flow data against your requirement 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 performance curves rather than a single rated figure, so there is no one number we can quote. Send us your application and required flow, and we will confirm the datasheet curve data for this size 400, 3/8 in unit on request before you order.
W selects the 5 um filter element instead of the 40 um standard, giving finer removal of water and particulate for sensitive downstream components. M selects the manual drain, so condensate is released by hand at intervals rather than automatically; differential-pressure (blank) and automatic (A) drains are available on other GFR codes.
