The AirTAC GFR600-20 AirTAC Filter Regulator G3/4, 40 um, 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 PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20 is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G3/4 (BSPP) port, a 40 um filter element, a manual drain on the bowl, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. Regulation range is 0.05-0.9 MPa (7-130 psi) and the embedded square gauge reads in psi, so you can set and monitor working pressure directly at the unit. The bowl on this 600 size is aluminium alloy.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", drain choices (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scale choices and G or NPT thread options alongside the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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 0.05 - 0.9 MPa (7 - 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-use air preparation for the pneumatic cylinders and grippers on a bottling or filling line: the 40 um element strips water and pipe scale before they reach the valve island, and the regulator holds a steady working pressure so fill and capping motions stay repeatable. The check valve keeps the circuit pressurised during brief supply dips.
Filtered and regulated air for the clamping and tool-change cylinders on a machining centre. Clean air protects the directional valves and cylinders from contamination, the psi gauge lets the setter verify clamp pressure at the unit, and the reverse valve prevents the fixture losing clamp pressure if the shop air drops.
A branch take-off from a building's compressed-air ring main serving lab benches and pilot-plant skids. The 40 um grade and manual-drain aluminium bowl suit a supervised environment where an operator can bleed condensate on a schedule, and the regulator sets a safe low pressure for bench-top pneumatic apparatus.
Size 600 with a G3/4 port is the largest step in the GFR range; step down to 200/300/400 if your line's flow demand is lower, since port size tracks the flow curve rather than a single rating. Drain type is a real decision: manual (this unit) means an operator opens the drain periodically, while automatic or differential-pressure drains handle condensate without attention - manual-drain units also carry the wider 0.05-0.9 MPa regulation range. The 40 um element is standard; specify code W for the 5 um grade where downstream equipment needs finer filtration. The square gauge here reads in psi; MPa and bar scales are also available. Thread is G (BSPP) on this unit; PT is the catalogue standard and NPT is an order option. A mounting bracket can be ordered (this configuration ships without one).
Because flow is published as curves and not a single rated number, 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. The reflux valve permits reverse flow 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 l/min, m3/h or SCFM figure. Send us your required flow and working pressure and we will confirm the datasheet curve values for the GFR600 size against your application before you order.
The M in the code means the bowl drain is opened by hand to discharge collected condensate, which suits installations where someone checks the unit on a schedule. Automatic (A) and differential-pressure (blank) drains are catalogue options on the same GFR600 size if you want condensate handled without operator attention. Note the manual-drain version also carries the wider 0.05-0.9 MPa (7-130 psi) regulation range.
