The AirTAC GFR600C20MJF2WK AirTAC Filter Regulator PT3/4 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 GFR600C20MJF2WK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 5 um element (the fine grade; 40 um is the standard option) and holds a regulated downstream pressure adjustable from 0.05 to 0.9 MPa (7-130 psi). This size 600 unit is specified with a PT3/4 port on PT thread, a manual drain for emptying the bowl, an embedded square pressure gauge reading in psi, and a reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Because the size 600 bowl is aluminium alloy, it suits duty where a polycarbonate bowl is not preferred.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, a choice of drain type (differential-pressure, automatic or manual), filter grade 40 um or 5 um, gauge scale MPa, psi or bar, G/NPT thread options and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.15 - 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.

Mounted ahead of a directional-valve manifold on a packaging or assembly machine, this unit filters the plant air to 5 um and holds a steady regulated pressure to the valves, with the psi gauge giving operators a local setpoint reading.
On a machining centre's pneumatic supply for tool-change clamps and chip-clearing jets, the 5 um element protects sensitive pilot valves from particulate while the regulator holds the clamp pressure the machine builder specified.
At a 3/4-inch air drop feeding quarter-turn actuators and positioners on a process line, the GFR600 combines water and particle removal with stable regulation, and the manual drain suits a supervised utility corridor.
Size and port are the first choice: the 600 series is the largest GFR frame, and this unit carries a PT3/4 port on standard PT thread (G and NPT are catalogue options to order). Step up or down a size when your line flow demands it - we confirm the published flow curve against your application before you order. Drain type matters in practice: this configuration has a manual drain, which suits attended installations where an operator bleeds the bowl on a routine; automatic or differential-pressure drains suit unattended lines. The 5 um element (code W) is the finer grade versus the 40 um standard - choose it where downstream valves and instruments are sensitive to finer particulate. The embedded square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. A reverse/check valve is fitted on this unit, and no mounting bracket is included (bracket code J).
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 number, so we do not quote a l/min, m3/h or SCFM figure here. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing against the datasheet curve on request before you order.
This configuration carries code M, meaning the bowl is emptied by hand - a good fit where the unit is checked during routine rounds. The GFR family is also available with a differential-pressure drain (the default) or an automatic drain (code A); tell us the installation and we will quote the matching variant.
