The AirTAC GFR600C20MF2WTK AirTAC Filter Regulator NPT3/4, 5 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 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 GFR600C20MF2WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a manual drain bowl in aluminium alloy, a fine 5 um filter element, an embedded square gauge reading in psi, a reverse/check valve, and an included mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.05-0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, PT/G/NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options, and low-pressure or standard regulator types. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures 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 0.15 - 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.

Feeds clean, regulated air to the tool-change clamping and pallet-clamp circuits of a CNC machining centre, with the 5 um element protecting tight-tolerance valves and the psi gauge giving operators a direct setpoint readout.
Sits at the drop point on a cartoning or wrapping line, filtering condensate out of the plant air before it reaches cylinder-driven sealing and folding stations, with the check valve holding downstream pressure if the supply dips.
Installed at a 3/4 in ring-main drop serving a row of pneumatic assembly stations, one unit filtering and regulating the whole cell instead of separate filter and regulator bodies, with manual drain bled during shift start-up checks.
Start with the port step: size 600 in 3/4 in NPT suits lines with substantial air demand, and the next size up or down changes both port and flow capacity - match the step to your consumption rather than oversizing blindly. Choose the drain to suit access: manual drain (this unit) needs an operator to bleed the bowl, while automatic and differential-pressure drains discharge condensate without attention. Choose 5 um (this unit) where downstream equipment needs finer filtration, or 40 um where coarser protection is enough. The square gauge here reads psi; MPa and bar scales are available, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are order options - this unit is ordered in NPT. A bracket is included; J-coded variants omit it.
Because flow is published as curves and not as a single rated figure, 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. 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, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow figures from the datasheet for this exact model before you order.
A manual drain holds condensate in the aluminium alloy bowl until an operator opens the drain - straightforward and reliable where the unit is accessible and checked routinely, such as at a supervised machine drop. If the unit will sit in a location that is not visited daily, the automatic or differential-pressure drain variants of the same GFR600 size discharge condensate without attention; the regulation range of 0.05-0.9 MPa (7-130 psi) applies to this manual-drain version.
