The AirTAC GFR600C20AF1WT AirTAC Filter Regulator NPT3/4 5 um 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 GFR600C20AF1WT is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air and holds downstream pressure in one adjustable stage. This 600-size unit is fitted with a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that expels collected condensate without manual attention, and an embedded square gauge scaled in MPa for direct setting. The maximum working pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy rather than polycarbonate.
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, square or round gauges with MPa, psi or bar scales, and G (BSPP), NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Installed on the 3/4 in drop feeding a CNC machining cell, the unit strips water and swarf-carrying particulate from the shop air supply and holds a steady regulated pressure to the cell's air-operated clamps and tool changers. The automatic drain keeps condensate off the floor on a line that runs unattended across shifts.
Mounted ahead of the valve manifold on a carton-forming and sealing conveyor line, the filter regulator conditions the air driving cylinders, vacuum generators and flap actuators. The 5 um element protects tight-tolerance valve spools, and the MPa gauge lets maintenance set and verify line pressure at a glance.
Fitted at the wall regulator station of a heavy-vehicle service bay, the unit conditions the shop air used for impact wrenches, air jacks and tyre-cage inflation rigs. The 3/4 in port matches the bay's main drop, the 5 um grade keeps moisture and grit out of tool couplings, and the automatic drain copes with the heavy condensate load of a compressor-fed garage main.
Choose the 600 size when your line runs at 3/4 in porting and the larger body suits the flow you need; smaller 200/300/400 sizes step down in port and flow. This unit is already specified with the finer 5 um element - select 40 um instead if your application tolerates coarser filtration and you want the standard grade. The automatic drain suits unattended duty; a manual drain is the choice where you want deliberate, supervised purging. The square gauge here reads in MPa; psi and bar scales and an external round gauge are catalogue options. NPT is the thread on this unit; G (BSPP) and PT are the other orderable options. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A in the code GFR600C20AF1WT specifies an automatic drain, which expels collected condensate from the bowl without anyone opening it - the right choice for unattended or high-humidity installations. The catalogue also offers manual drains and the differential-pressure default, so a different drain type can be ordered as a separate model code if your duty suits it better.
