The AirTAC GFR400C10MC2WGK AirTAC Filter Regulator G3/8, 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 GFR400C10MC2WGK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration carries a G3/8 (BSPP) port, a fine 5 um filter element (the W grade, against the 40 um standard), a manual drain on the bowl, an external round gauge scaled in psi, a built-in reverse/check valve, and a mounting bracket. The regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), the unit accepts up to 1.0 MPa (145 psi) inlet, and it operates from -5 to 70 C in non-freezing air.
This is a genuine AirTAC part from the GFR family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and options for drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT to order) and bracket. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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.

Placed ahead of the machine's solenoid valves, the 5 um element strips water and fine particulate from the shop air while the regulator holds a steady setting for clamps and tool-change cylinders; the check valve holds the circuit if supply pressure dips.
On benchtop analysers and sample-handling actuators that are sensitive to dirt and pressure drift, the fine 5 um grade and the psi-scaled round gauge let technicians filter and set a repeatable supply pressure at each station.
Feeding pneumatic cylinders on a carton-forming and sealing conveyor, the unit cleans the compressed air, regulates it to the actuator's working band, and the reverse/check valve keeps the downstream setting intact during upstream pressure loss.
Step through the decodable choices before ordering: pick the size and port against the flow your line needs (400 sits above the 200/300 sizes and below 600, here with a 3/8 in port); choose the element grade, where 5 um (this unit, code W) protects finer components than the 40 um standard; choose the drain, where manual suits supervised installations while automatic and differential-pressure drains suit unattended ones; and set the gauge style and scale - this unit has an external round gauge in psi, with square embedded gauges and MPa/bar scales available. Thread is G (BSPP) here; PT is the standard and NPT is an order option, and a bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated figure, so send us your application and we will confirm the 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 GFR400 as curves rather than a single rated number, so there is no one l/min or SCFM figure we can quote honestly. Tell us your application and required flow, and we will confirm the sizing against the datasheet on request before you order.
The W code in the model sets the fine 5 um grade, which suits downstream components that need cleaner air than the 40 um standard provides, and the M code sets a manual drain, which suits installations where an operator can bleed the bowl on a routine round. If the unit will run unattended, ask us about the automatic or differential-pressure drain variants of the same GFR400 size.
