The AirTAC GFR600C20MNTK AirTAC Filter Regulator NPT 3/4 in 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 GFR600C20MNTK is a filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This size 600 unit is built for 3/4 in NPT ports, with a 40 um standard filter element and a manual drain bowl. Because it is size 600, the bowl is aluminium alloy. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and no gauge is fitted on this configuration, so add your own if a local pressure readout is needed. A reverse/check valve is fitted, holding downstream pressure if the upstream supply drops. 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 spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um element (code W), gauges in different scales, G or NPT threads, and a reverse/check valve. 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 0.15 - 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 at the 3/4 in take-off from a plant air header to clean condensed water and particulate out of the supply and hold a fixed regulated pressure for the whole line's actuators.
Feeding air to press cylinders and clamping fixtures where the operator sets one stable working pressure; the manual drain suits a machine tended each shift, and the check valve holds the set pressure if the supply dips.
Mounted at the machine inlet to condition air before it reaches diverters, lifters and packaging cylinders, with the included bracket fixing the unit to the machine frame.
Start with the port and size step: this unit is size 600 with 3/4 in NPT ports, the largest step in the GFR range, so match it to the pipe size and air demand of the circuit it feeds. Drain type is a real choice: this configuration has a manual drain, which suits attended installations where an operator can bleed the bowl; automatic or differential-pressure drains suit unattended lines. The 40 um element is the standard grade; specify the 5 um W option where finer particulate removal is required. No gauge is fitted here, so plan for an external gauge if you need a setpoint readout. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included with this unit.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your flow and pressure requirements and we will confirm the datasheet figures against your application 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 family as curves rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm the datasheet curve figures for this 3/4 in size 600 unit against your application before you order.
This configuration carries code M, a manual drain: the accumulated condensate is bled from the aluminium bowl by hand, which suits attended machines. The same GFR600 body is also available with an automatic drain (code A) or the differential-pressure drain (blank) for unattended lines, and with a 5 um element (code W), a gauge, or a G or NPT thread if you prefer a different configuration.
