The AirTAC GFR40010JF2G AirTAC Filter Regulator G3/8, 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 GFR40010JF2G is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 unit is fitted with a G3/8 (BSPP) port, the standard 40 um filter element and a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element is high enough. The built-in square gauge reads in psi, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). The polycarbonate bowl is rated for a maximum inlet pressure of 1.0 MPa (145 psi) and the unit operates from -5 to 70 C in non-freezing conditions. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um element (code W) where finer filtration is needed, and embedded square or optional external round gauges scaled in MPa, psi or bar. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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 clean, regulated air to the grippers and actuation circuits of a six-axis robot cell, where the 3/8 in port and psi-reading square gauge let the integrator set and verify working pressure at the cell drop.
Conditioning the air feeding cylinders and diverters on a carton packaging line, with the 40 um element catching pipe scale and the differential-pressure drain keeping condensate out of the valve manifold.
Providing filtered, adjustable air to a lab bench running pneumatic test fixtures, where the psi gauge and 0.15-0.9 MPa adjustment range allow repeatable setpoints between experiments.
Start with the size and port: 200, 300, 400 and 600 step up in both port size and flow capacity, so match the GFR400's 3/8 in connection against the air consumption of the equipment downstream. Choose the drain type to suit the installation: differential-pressure (this unit) drains on pressure drop, automatic drains on a timer-free cycle, and manual requires an operator to open the bowl. Filter grade is 40 um as standard; specify the W code for 5 um where finer protection is needed. Gauge scale can be MPa, psi or bar, with an embedded square gauge standard and an external round gauge optional. Thread is PT as standard with G and NPT available to order, and a bracket can be added where panel or wall mounting is required. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request.
This model's differential-pressure drain discharges condensate automatically whenever the pressure drop across the 40 um element rises high enough, with no operator involvement. The automatic option drains on its own cycle regardless of pressure drop, while the manual drain requires someone to open the bowl. Manual-drain versions also carry a wider 0.05-0.9 MPa (7-130 psi) regulator adjustment range instead of 0.15-0.9 MPa (20-130 psi).
