The AirTAC GFR60020MC2WTK AirTAC Filter Regulator NPT3/4, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR60020MC2WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is decodes to a 3/4 in NPT port, the fine 5 um filter element (code W), a manual drain on the bowl, an external round pressure gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure if the supply drops. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Because this is the 600 size, the bowl is aluminium alloy, and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um fine filtration, gauge style and scale options, and G or NPT thread variants. Flow for this series is published as curves rather than a single rated figure, so 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.

Point-of-use conditioning on the 3/4 in main feeding a CNC machining centre: the 5 um element protects solenoid valves and spindle-area actuators from water and fine particulate, while the regulator holds a steady setting for clamping and tool-change circuits. The check valve keeps the setting if shop supply dips.
Filtering and regulating the air header that feeds grippers, stoppers and pusher cylinders on a bottling or packaging line. The 3/4 in port suits the line's main drop, the round psi gauge lets technicians verify the setting at a glance, and the manual drain is emptied during scheduled changeovers.
Conditioning the air feed to a paint booth or body-shop spray setup, where the 5 um grade limits water and particle carry-over to the spray gun and the regulator pins a consistent atomising pressure. The aluminium bowl and manual drain suit a supervised, shift-based workshop environment.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest in the GFR range, so step down to GFR200/300/400 if your line runs smaller ports and lower air demand. Choose the drain to match attendance: manual drain (this unit) needs someone to open it periodically, the automatic drain handles condensate unattended, and the differential-pressure default suits steady, continuous duty. Choose the 5 um element (code W) where downstream valves, cylinders or instruments need finer air than the 40 um standard element delivers.
Gauge style and scale are decodable choices: this configuration carries the external round gauge reading in psi, while an embedded square gauge with MPa, psi or bar scales is the standard alternative. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also orderable. A bracket is included for mounting. Because flow is published as curves rather than a single rating, 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. 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 figure that could mislead your sizing. Tell us your application and air demand and we will confirm the relevant datasheet curve and figures on request before you order.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl is released by hand, which suits attended installations on a maintenance schedule. If the unit will run unattended, order the same GFR600 size with drain code A for the automatic drain instead.
