The AirTAC GFR20008F2GK AirTAC Filter Regulator G1/4, 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 PT1/4" 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 GFR20008F2GK is a GFR200-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is a size 200 unit with a G1/4 (BSPP) port, standard 40 um filtration, a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough, and an embedded square gauge reading in psi. A reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost, and a mounting bracket is included for panel or frame fixing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, manual, automatic or differential-pressure drains, a 5 um (code W) filter grade option, and gauge scale choices. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range with this drain type is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, 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.

Feeding clamping cylinders on a CNC fixture: the 40 um element keeps machining swarf and condensed water out of the clamp valves, the regulator sets a stable clamp pressure read locally in psi, and the check valve holds the clamp if shop air drops.
Supplying the diverters, blow-offs and actuated gates along a packaging conveyor: one GFR200 body filters and regulates at the point of use, the differential-pressure drain keeps condensate moving out during production, and the bracket mounts the unit beside the line.
A filtered, regulated drop at an assembly workbench: operators get clean air at a set pressure shown on the psi gauge, the check valve prevents backflow between benches on a shared header, and the G1/4 port matches standard drop hose and fittings.
Size 200 with a 1/4 in port suits lighter air-preparation duties; step up to 300, 400 or 600 if your line needs more flow or a larger port. The differential-pressure drain on this unit handles condensate without daily manual draining - choose a manual drain (M) only where you prefer positive operator control, or an automatic drain (A) where the bowl must empty fully after shutdown. The standard 40 um element protects most pneumatic tools and valves; specify the 5 um W-grade element for more sensitive downstream equipment. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. This unit carries a G (BSPP) thread; PT is the standard and NPT is orderable. A bracket is included, and the fitted check valve holds downstream pressure on supply loss. Flow is published as curves, not a single rating, so 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and the air demand of your equipment and we will confirm the flow from the datasheet curves on request before you order.
This GFR20008F2GK has no drain code letter, which is the differential-pressure drain: it bleeds collected condensate out of the bowl automatically whenever the pressure differential across the filter element is high enough, so the bowl does not need manual draining in normal service. A manual drain (code M) or automatic drain (code A) version can be ordered instead if your application needs it.
