The AirTAC GFR400C10MJF2 AirTAC Filter Regulator 3/8 in PT 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 GFR400C10MJF2 is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This configuration is sized for a PT3/8 port, uses the standard 40 um filter element, and has a manual drain, so an operator opens the drain at the bottom of the polycarbonate bowl to release collected condensate. Regulation is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), max inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the embedded square gauge reads in psi. No mounting bracket is fitted and no reverse (check) valve is included.
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 include automatic, manual or differential-pressure drains, a 5 um (code W) element, G or NPT threads, gauge scale choices and bracket variants. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

Feeding filtered, regulated air to the pneumatic cylinders and valves on a carton-forming and sealing line, where a stable setpoint keeps gripper and clamp motions repeatable and the 40 um element catches pipe scale before it reaches the valves.
Conditioning the shop-air drop that supplies a CNC machining centre's pneumatic tool-clamp and chip-door cylinders, with the psi-scaled square gauge letting setters verify line pressure at a glance.
Supplying regulated air to spray guns in a vehicle refinish booth, where the manual drain lets the operator purge accumulated water from the bowl at the start of each shift before painting begins.
Choose the size by the flow your line needs: this unit is size 400 with a PT3/8 port, one step up in port and flow capacity from size 300. The drain is manual, which suits installations where someone is on site to bleed the bowl; automatic or differential-pressure drains are available if you would rather not rely on an operator. The 40 um element is the standard grade for general plant air; specify the 5 um (W) option where finer filtration is needed. The square gauge here is scaled in psi, and MPa or bar scales can be ordered. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket can be added. Flow for this series is published as curves, not a single rating, so send us your air demand 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 GFR400 series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application's air demand and we will confirm the flow and sizing from the datasheet on request.
The M in this code specifies a manual drain: condensate collected in the polycarbonate bowl is released by opening the drain by hand. Choose it where an operator is regularly present; choose the automatic or differential-pressure drain option where the unit runs unattended.
