The AirTAC GFR600C20AF2WG AirTAC Filter Regulator G3/4 5 um Auto Drain 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 See datasheet 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 GFR600C20AF2WG is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a G3/4 (BSPP) port, a 5 um filter element for finer particle removal than the standard 40 um grade, and an automatic drain that expels collected condensate without manual attention. The size-600 bowl is aluminium alloy, and the unit includes a mounting bracket. The standard-type regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the fitted embedded square gauge reads in psi so downstream pressure can be set and monitored at a glance. Maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge scale options, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Point-of-entry conditioning for a spray booth's 3/4 in air feed: the 5 um element strips fine particulate and the automatic drain clears condensate, while the regulator holds a steady set pressure to the booth's air controls.
A main-line filter regulator feeding the machine's pneumatic valves and clamps. The psi-scale square gauge lets the setter verify setpoint at the machine, and the automatic drain keeps the metal bowl emptied between maintenance rounds.
Conditioning the 3/4 in supply that feeds a packaging machine's cylinder and valve bank: clean, regulated air at a fixed psi setpoint, with the 5 um grade protecting sensitive directional valves from fine contamination.
Step through the decodable choices before ordering. Size 600 with its 3/4 in port sits at the top of the GFR range and suits higher-flow branch and main lines; if your demand is modest, a 200, 300 or 400 unit on a smaller port may be the better economic fit. Drain type matters in practice: this unit's automatic drain suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the alternatives when you prefer controlled blowdown. The 5 um element (code W) is the finer choice over the standard 40 um grade where downstream equipment tolerates less particulate. Gauge scale (MPa, psi or bar), thread family (PT standard, G or NPT to order) and the bracket are all specified at ordering.
One honest routing note: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application's flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. 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 GFR600 series as performance curves rather than a single rated figure, so we do not state a flow number here. Send us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The code spells it out: W selects the optional 5 um filter element instead of the 40 um standard grade, and A selects the automatic drain instead of the default differential-pressure drain. The 5 um grade suits downstream equipment that tolerates less particulate, and the automatic drain suits installations where manual draining is impractical.
