The AirTAC GFR40010AF2WGK AirTAC Filter Regulator G3/8, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" ports, a automatic 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 GFR40010AF2WGK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This configuration is built on a G3/8 (3/8 in) port, a 5 um filter element (code W, against the 40 um standard), an automatic drain that clears condensate from the PC bowl without daily attention, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for manual or differential-pressure drains, 40 um or 5 um elements, MPa, psi or bar gauge scales, G or NPT threads in place of the PT standard, and a mounting bracket (included here). Flow is published as curves rather than a single rated figure, 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.

Cleaned and regulated air to pneumatic clamps and tool-changer cylinders on a machining cell, with the check valve holding clamp pressure through supply dips.
Regulated air for stopper and diverter cylinders along a bottling conveyor; the 5 um element protects valve spools from water and pipe scale.
Filtered, regulated air for grippers and lift stages in sample-handling automation, where the psi gauge gives technicians a readable setpoint.
Size the unit by port and expected air demand: this one steps up to 3/8 in on the size-400 body, so check your line's requirement against the GFR400 flow curve before ordering - we will confirm the curve and datasheet on request. The decodable choices are drain type (automatic here; manual allows a lower 0.05 MPa setpoint floor; differential-pressure is the catalogue default), filter grade (5 um fitted versus the 40 um standard), gauge scale (psi here; MPa and bar available), thread (G here; PT is the standard and NPT is an order option), and the included mounting bracket. Ask us to check sizing against your application 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 GFR400 as curves rather than a single rated number, so we do not quote a figure here. Send us your line pressure and air demand and we will confirm the curve and datasheet for this exact model on request.
The A in the code fits an automatic drain, which expels collected condensate from the PC bowl without daily attention - useful on unattended installations. With automatic or differential-pressure drains the regulation range is 0.15-0.9 MPa (20-130 psi); a manual-drain version widens the floor to 0.05 MPa (7 psi). The 5 um W element and psi gauge are separate choices.
