The AirTAC GFR40010F2G AirTAC Filter Regulator G3/8, 40 um, psi gauge 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 GFR40010F2G is a size 400 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration has a 3/8 in port with G (BSPP) thread, a 40 um standard filtration element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough. The standard regulator covers 0.15-0.9 MPa (20-130 psi), and the embedded square gauge reads in psi so setpoints can be checked at a glance. The polycarbonate bowl suits the 400 size, a mounting bracket is included, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR400 series, one of four sizes (200/300/400/600) in the G-series line. Related configurations offer 5 um filtration (code W), manual or automatic drains, MPa or bar gauge scales, and NPT or PT threads. Flow is published in the catalogue as curves rather than a single rated figure, 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 a machining centre's tool-changer and clamping circuits, with the 40 um element catching pipe scale and the square psi gauge letting setters verify clamp pressure at the regulator.
Conditioning the air feeding pneumatic cylinders and diverters on a cartoning or case-packing conveyor, where the differential-pressure drain keeps condensate off the actuators without daily bowl checks.
A point-of-use filter regulator at the drop leg serving assembly stations, giving each bench its own 0.15-0.9 MPa setpoint and a bracket-mounted unit that stays clear of the work surface.
Size 400 with a 3/8 in port sits in the middle of the GFR range: step up to 600 or down to 300/200 as your line flow demands, since port size is the practical proxy for the flow the curves allow. Choose the drain to match maintenance access: this unit's differential-pressure drain needs no daily attention, an automatic drain (code A) empties continuously, and a manual drain (code M) suits attended installations. The 40 um element is the standard grade; specify 5 um (code W) only where finer pre-filtration is genuinely required. The square gauge here reads psi; MPa and bar scales are available, and an external round gauge is an option.
Thread is G (BSPP) on this model, with PT and NPT orderable as catalogue options - PT is the standard thread, so confirm which your pipework needs before ordering. A bracket is included for panel or wall fixing. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 GFR400 flow as curves in the catalogue, not as a single rated number, so there is no honest one-line figure to quote. Tell us your line pressure, set pressure and expected air demand, and we will confirm the datasheet flow figures for this 3/8 in size on request before you order.
This configuration has the default differential-pressure drain: condensate collected in the polycarbonate bowl is discharged automatically when the pressure differential across the 40 um element rises high enough. If you want continuous emptying regardless of differential, order the automatic drain (code A); if the unit is checked daily by an operator, the manual drain (code M) is the simpler choice.
