The AirTAC GFR30010AF2W AirTAC Filter Regulator 3/8in PT 5um Auto Drain 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 GFR30010AF2W is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, all in one body. This configuration is size 300 with a PT3/8 port, fitted with the 5 um filter element (code W), an automatic drain, and an embedded square pressure gauge reading in psi. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. The polycarbonate bowl is supplied with a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices of differential-pressure, automatic or manual, 40 um standard or 5 um filtration, and gauge options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

Filters and regulates the shop-air feed to a machining centre's pneumatic tool clamps and chip-sweep nozzles; the 5 um element helps protect the machine's fine pilot valves from particles and carryover water.
Conditions the air acting on cylinder-driven diverters, pushers and stoppers along a carton or bottle conveyor, with the automatic drain clearing condensate at a point nobody visits every shift.
Gives a carton-sealing station one filtered, pressure-steady air point for its sealing jaws and vacuum cup hold-downs, so jaw timing cylinders see clean air at a set pressure.
Start with the port: this unit is size 300 at PT3/8; step to size 200 or up to 400/600 if your line needs a different connection, and match the size step to the flow your circuit needs. Drain type is a real choice: differential-pressure (default), automatic as fitted here, or manual - automatic suits points that are hard to reach daily. Filter grade is 40 um standard or 5 um (code W) when finer protection is wanted; gauge is the embedded square type with MPa, psi or bar scales, and an external round gauge is optional. Thread is PT as standard, with G and NPT available as order options, and the bracket is included. 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 GFR series as curves, not as a single rated number, so we do not quote a figure on the page. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet curves on request before you order.
The W in the code selects the 5 um element instead of the 40 um standard, giving finer particulate removal for downstream valves, cylinders and instruments; the A selects the automatic drain, which expels collected condensate without manual attention. The 40 um grade and a manual or differential-pressure drain remain available in the same GFR300 size if you prefer them.
