The AirTAC GFR600C20MLF2 AirTAC Filter Regulator 3/4 in PT 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 GFR600C20MLF2 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 600 unit is made for 3/4 in PT ports, carries the standard 40 um filter element, and uses a manual drain, so an operator opens the drain valve to purge collected water on a check round. It is the low-pressure type, and the embedded square gauge fitted to this model reads in psi. The bowl is aluminium alloy, as fitted on the larger 600 frame, and the maximum inlet pressure is 1.0 MPa (145 psi) with a working temperature of -5 to 70 C, non-freezing. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and the catalogue options include automatic, manual or differential-pressure drains, a finer 5 um element (code W), gauge scales in MPa, psi or bar, and G or NPT threads to order. Flow and other datasheet figures are published as curves rather than a single rating, so we confirm them on request 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 filtered, pressure-stabilised air to spray guns and air motors on a coating line, where the 40 um element catches water and pipe scale and the regulator holds gun pressure steady at the setpoint.
Supplying pneumatic cylinders and actuators on a carton-sealing or palletising conveyor, with the manual drain purged during shift checks and the square psi gauge giving operators a readable setpoint.
Setting air pressure for quarter-turn valve actuators on a process skid, where the low-pressure type matches a modest control pressure and the 3/4 in PT port feeds the actuator manifold.
Pick the size and port by the air your line consumes: 600 is the largest G-series frame, and this model is drilled for 3/4 in PT. The low-pressure type suits installations whose control pressure sits below the standard regulator range - ask us to confirm the exact adjustment range against your setpoint before ordering. Drain choice is a real decision: manual (this model) fits attended installations where an operator blows down the bowl, while automatic or differential-pressure drains suit unattended lines. The 40 um element is standard; specify code W for 5 um if downstream equipment needs finer filtration. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and the included bracket complete the choices. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing from 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 GFR series as curves rather than a single rated figure, so we do not quote one number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
This model uses a manual drain: an operator opens the valve to purge collected water, which suits attended installations on a regular check round. The GFR family is also available with automatic or differential-pressure drains - tell us which fits your maintenance routine when ordering.
