The AirTAC GFR400C10JF2TK AirTAC Filter Regulator NPT 3/8 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 GFR400C10JF2TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is sized for 3/8 in NPT ports, filters to 40 um (the standard grade; 5 um is available as code W), drains by differential pressure, and carries an embedded square gauge reading in psi. A reverse (check) valve is fitted, and the unit is supplied without a mounting bracket.
It is a genuine AirTAC part from the GFR400 series, one of four sizes (200, 300, 400, 600) that step up in port and flow. Maximum inlet pressure is 1.0 MPa (145 psi), the standard setting range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The 400-size bowl is polycarbonate. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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 a machining center's compressed-air drop: water and pipe-scale particulate are filtered out and the clamp and tool-change actuators see a steady, set pressure.
Feeding pick-and-place and carton-sealing cylinders on a packaging conveyor, where one body handles both filtration and regulation at the drop and the psi gauge gives line staff a local reading.
Conditioning the supply to air-operated assembly fixtures and clamps in an electronics assembly cell, with the 40 um element catching debris and the check valve fitted in the circuit.
Size and port are the first choice: the G-series steps through sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, so pick the 400 / 3/8 in NPT step where it matches your line's air demand - we can check the published flow curves against your application before you order. Drain type is a real decision: differential-pressure (this unit) discharges condensate while air flows, automatic (code A) drains without operator action, and manual (code M) needs bleeding by hand; note the setting range differs by drain type (0.15-0.9 MPa for this unit's drain). Filter grade is 40 um standard or 5 um with code W. Gauge scale is MPa, psi or bar (this unit: square, psi), thread can be PT (the standard), G or NPT (this unit: NPT), and a bracket is optional - this unit comes without one.
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 G-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your inlet pressure, set pressure and expected air demand and we will confirm the sizing from the datasheet before you order.
This unit uses the differential-pressure drain (the default): it discharges collected condensate while air is flowing, with no operator action. Choose code A for automatic draining on intermittently flowing lines, or code M for manual draining where an operator can bleed the bowl; note the regulator setting range differs by drain type (0.15-0.9 MPa for automatic and differential-pressure, 0.05-0.9 MPa for manual).
