The AirTAC GFR60020MNTK AirTAC Filter Regulator NPT3/4, 40 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 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 GFR60020MNTK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and sets downstream pressure. This size-600 unit carries a 3/4 in NPT port, the standard 40 um filter element, and a manual drain bowl in aluminium alloy. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi) on this manual-drain version, and a reverse/check valve is fitted. No gauge is supplied with this code, so add a gauge separately if a visual pressure reading is needed at the point of use.
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 for drain type, 5 um filtration (code W), gauge and scale, thread form and bracket. Flow figures are published as curves rather than a single rating; ask us and we will 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 0.05 - 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.

Dropping off a 3/4 in compressed-air main to feed a machining cell: the unit strips water and pipe-scale from the main supply and holds a steady regulated pressure to the cell's air tools and actuators, with the manual drain emptied during operator rounds.
Feeding cylinders and air-operated valves on a cartoning or case-packing conveyor: filtered, regulated air keeps downstream valve shifting consistent through the shift, and the check valve holds the set circuit if supply pressure dips.
Supplying pneumatic nutrunners, impact drivers and clamping fixtures at a bench assembly station: the regulator lets each station set its own working pressure independent of the header, while the 40 um element keeps grit out of the tools.
Start with the port step: this unit is the size-600 body with a 3/4 in NPT thread, the largest GFR size, so size up to it when your line runs at 3/4 in and you want headroom in the body rather than reducers. Drain choice matters in service: manual drain needs an operator to open the bowl, while automatic and differential-pressure drains discharge condensate themselves - this code is the manual-drain version. Filtration is the standard 40 um element; specify code W for 5 um where finer particulate removal is required. Gauge is not fitted on this code, so plan a separate gauge if you need to read set pressure. Thread is NPT here; PT is the standard form and G (BSPP) is an order option. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so send us your flow and pressure conditions and we will confirm the right size 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 family as curves rather than a single rated number, so there is no one rated-flow figure we can quote for this unit. Send us your line pressure and required flow and we will confirm the datasheet curve figures for the GFR600 size on request before you order.
The N in GFR60020MNTK means no gauge is fitted with this unit. GFR regulators accept a gauge option - an embedded square gauge or an external round gauge, with MPa, psi or bar scales - so order the gauge variant or add a gauge separately if you need a visual reading at the regulator.
