The AirTAC GFR400C10MJC1WT 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 GFR400C10MJC1WT is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/8 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, and a round external pressure gauge scaled in MPa. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with manual drain, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 400 the bowl is polycarbonate (PC); no mounting bracket is included with this code.
This is a genuine AirTAC part from the G-series filter regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and a choice of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as order options), and bracket. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure 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 clean, pressure-controlled air to the tool-change and clamping circuits of a CNC machining centre, with the 5 um element protecting directional valves and cylinders from particles and the regulator holding a set pressure for consistent clamping force.
Sits at the drop to a spray gun or atomising station in a finishing line, where the 5 um grade and water removal help keep the air supply clean for coating work and the regulator lets the operator set gun supply pressure at the point of use.
Prepares air for the pneumatic cylinders and grippers on a carton-forming or case-packing conveyor line, combining filtration and regulation in one body to save panel space while keeping actuator pressure stable through the shift.
Start with the size and port: the G-series steps through sizes 200, 300, 400 and 600, each opening up larger ports and more flow capacity, so match the 3/8 in NPT port here against your line size and expected air demand. This unit uses a manual drain, which suits installations where an operator can bleed the bowl on a routine; if the unit will sit unattended, ask about the automatic or differential-pressure drain options. The 5 um element in this code is the finer grade (40 um is the standard); choose it where downstream equipment is sensitive to finer particles. Gauge style and scale (square embedded or round external; MPa, psi or bar) and thread (PT standard, G or NPT) are order choices, and a bracket can be added where this no-bracket code does not include one. Flow for this series is published as curves, not a single rating, so 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a flow number for this unit. Send us your line size, working pressure and air demand, and we will confirm the sizing against the datasheet on request before you order.
The M in this code specifies a manual drain: condensate collected in the bowl is released by hand, which suits stations visited regularly by an operator. Where the unit runs unattended, the catalogue offers automatic (A) and differential-pressure (blank) drain options instead; ask us to quote the equivalent code for your duty.
