The AirTAC GFR400C10MF2GK AirTAC Filter Regulator G3/8, 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 GFR400C10MF2GK is an AirTAC GFR400 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration has a G3/8 (BSPP) port, a manual drain bowl, a 40 um filter element, an embedded square gauge reading in psi, and a built-in reverse (check) valve to hold downstream pressure if the supply drops. A mounting bracket is included.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, PT as standard and G or NPT threads to order, plus a choice of automatic, manual or differential-pressure drains, 40 um or 5 um (W) filter elements, and gauge scales in MPa, psi or bar. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Placed ahead of the solenoid valve bank on a packaging line, this unit strips water and particles from the plant air and holds a steady regulated pressure, while the check valve keeps the valve station supplied during brief supply dips.
Mounted at the drop for a conveyor section driving gate diverters, stoppers and pusher cylinders, the GFR400C10MF2GK cleans the air and lets maintenance set one stable pressure for consistent actuator speed and gentle product handling.
On a robotic assembly cell with pneumatic grippers and clamping cylinders, this filter regulator conditions the air at the cell drop, protects the gripper seals from dirt and moisture, and gives operators a local psi gauge for repeatable clamping force.
Size 400 with its 3/8 in port is the step to take when your circuit needs more flow than a GFR300 or GFR200 can pass; drop a size for compact tool circuits and step to GFR600 for larger headers. The manual drain here suits installations where the unit is accessible and an operator can bleed condensate on a set schedule; choose the automatic or differential-pressure drain option if you need hands-off condensate removal. The standard 40 um element protects most pneumatic valves, cylinders and tools; specify the W code for the 5 um element where finer filtration matters. The square gauge on this unit reads in psi, with MPa and bar scales available and an external round gauge as an option. Thread is G (BSPP); PT is the standard and NPT can be ordered. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 rated flow number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request before you order.
This unit has a manual drain: condensate collected in the bowl is released by hand, which suits accessible installations checked on a regular maintenance round. If the unit will be mounted out of reach or run unattended, order the same model with the A (automatic) drain code so condensate is expelled without operator intervention.
