The AirTAC GFR40010JC2 AirTAC Filter Regulator PT3/8, 40 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 PT3/8" 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 GFR40010JC2 is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with PT3/8 ports (PT is the standard thread; G and NPT are order options), a 40 um standard filter element, a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, and a round pressure gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and no mounting bracket is included. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, a 5 um (code W) filter element option, and gauge scale choices in MPa, psi or bar. Flow figures for this series are published as curves rather than a single rating, 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.

Point-of-use conditioning on a CNC machining centre: the 40 um element strips water and swarf-carrying particulate before it reaches solenoid valves and tool-change cylinders, while the psi gauge lets setters set and verify the regulated supply pressure at the drop.
Feeding spray guns and air-assisted applicators in an automotive paint booth, where clean, moisture-reduced air at a stable set pressure keeps finish quality consistent; the differential-pressure drain handles condensate without daily manual blowing-down.
Conditioning and regulating the supply to pneumatic cylinders and diverters on a packaging conveyor line, so stopper and pusher stations see steady pressure through the shift; the 3/8 in PT port suits a mid-size machine air ring main.
Start with the port and size step: this unit is size 400 with PT3/8 ports, one of five sizes (200/300/400/600) covering 1/8 to 1 inch ports - step up a size if your line needs more flow capacity. Filter grade is a real choice: the 40 um element fitted here is the standard; specify code W if you need 5 um. Drain type matters: differential-pressure (as fitted) needs no attention, automatic drains continuously, and manual drain suits infrequent condensate loads. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket can be added (this unit is supplied without one). Flow for the G-series is published as curves, not a single rated figure, so send us your application details 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 G-series flow as performance curves rather than a single rated figure, so there is no one flow number we can quote honestly. Tell us your inlet pressure, set pressure and downstream demand, and we will confirm the sizing from the datasheet curves before you order.
The C2 code on GFR40010JC2 specifies the optional external round gauge with a psi scale. The embedded square gauge is the standard fitting, and MPa or bar scales are also available - so you can match the gauge to the units your maintenance team already works in.
