The AirTAC GFR400C10MJF2K AirTAC Filter Regulator PT3/8, 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 GFR400C10MJF2K is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is the 400 size with a 3/8 in PT port, a manual drain on the polycarbonate bowl, a 40 um standard filter element, an embedded square gauge scaled in psi, a reverse (check) valve fitted, and no mounting bracket (code J). Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. The standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) with this manual-drain version.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge and thread options (PT standard; G and NPT are order options). Flow is published as curves rather than a single rated figure, so ask us and we will confirm the 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.

Point-of-use conditioning on the air drop feeding clamps, tool-changer cylinders and chip-ejection actuators on a CNC machining centre: water and swarf-carrying moisture are stripped out and the regulator holds a steady setting so clamping force stays repeatable across the shift. The manual drain suits a cell where an operator already walks the machine daily.
Conditioned air for the carton-sealing and case-erector cylinders along a packaging conveyor line. The 40 um element protects the solenoid valves and cylinder seals from water and particulate, the check valve holds the set pressure if the upstream supply dips, and the psi-scaled square gauge lets line staff verify the setting at a glance.
Air preparation on a skid actuating solenoid-controlled process valves in a water-treatment or chemical-dosing plant. The filter-regulator delivers clean, regulated air to the positioners and actuators, the manual drain is serviced during scheduled rounds, and the 3/8 in PT port ties into the skid's instrument-air tubing.
Step up or down the size/port ladder (200, 300, 400, 600) to match the pipe and the air demand of the machine being fed - the 400 size with its 3/8 in PT port sits in the mid-range of the family. Choose the drain to suit access: this unit has a manual drain (M), which you operate by hand; automatic (A) and differential-pressure (blank) versions are available if the bowl cannot be reached easily. Filtration is the 40 um standard element; specify W for the 5 um grade where downstream equipment needs finer air. The fitted square gauge reads in psi (scale 2); MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order; this code carries no mounting bracket.
Because flow is published as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm sizing against the datasheet curves 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, not as a single rated number, so we do not state a flow figure on this page. Tell us your application - the machine, its pressure setting and its air demand - and we will confirm the relevant datasheet curve and check the sizing for you before you order.
This unit has code M, so accumulated condensate is drained from the bowl by hand - a good choice where the unit is accessible during daily checks. The family also offers automatic drain (A) and differential-pressure drain (blank, the default). Note that with the manual-drain version the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); the automatic and differential-pressure versions adjust from 0.15-0.9 MPa (20-130 psi).
