The AirTAC GFR40010JF3TK AirTAC Filter Regulator 3/8 NPT, Bar 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 GFR40010JF3TK is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has 3/8 in NPT ports, a 40 um standard filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge scaled in bar, and a built-in reverse/check valve that holds downstream pressure if the supply drops. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C (non-freezing). The polycarbonate bowl suits the 200/300/400 sizes; only size 600 uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR line is available in sizes 200, 300, 400 and 600 with matching port sizes, a choice of differential-pressure, automatic or manual drain, a 5 um element (code W) in place of the standard 40 um, square or round gauges with MPa, psi or bar scales, PT (standard), G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rating, so ask us to 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.

Filtering and regulating the supply to a pneumatic press or clamping station, with the check valve holding clamp pressure if the plant air line dips mid-cycle.
Conditioning air for conveyor diverters, case sealers and bagger cylinders on a packaging line, where clean, dry, regulated air keeps cycle behavior consistent.
A compact filter-regulator at individual machine drops in a factory, replacing a separate filter and regulator pair where panel space or piping runs are tight.
Start with the port step: this unit is size 400 with 3/8 in NPT ports; step up to size 600 or down to 300/200 if your line size or required flow differs. Choose the drain to suit access: differential-pressure (this unit, no operator action), automatic, or manual where you want controlled blowdown. Pick the filter grade: 40 um standard for general air prep, 5 um (code W) for finer protection of valves and cylinders. Select the gauge scale - MPa, psi or bar - and the thread: PT is the standard, with G (BSPP) and NPT as orderable options. Brackets are optional; this code specifies no bracket.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as performance curves rather than a single rated figure, so we do not state a flow number here. Contact us with your application details and we will confirm the flow and sizing against the datasheet curves before you order.
K means a reverse/check valve is fitted, so the unit holds downstream pressure if the upstream supply is lost. The drain on this unit is differential-pressure type: collected condensate is discharged automatically by the pressure differential during normal flow, with no manual draining required. Automatic (A) and manual (M) drain versions are available in the same family.
