The AirTAC AirTAC GFR60020MLC2WGK Filter Regulator G3/4 5um 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 GFR60020MLC2WGK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a G3/4 (3/4 in) port with G thread, a fine 5 um filter element (the W grade, tighter than the 40 um standard), a manual drain on the bowl, and the low-pressure regulator type for setpoints below the standard range. It ships as coded with a round external gauge scaled in psi, a fitted reverse/check valve, an included mounting bracket, and - because size 600 uses an aluminium alloy bowl - a metal pressure vessel suited to larger installations. 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 up to 1 in, and each size can be ordered with your choice of drain type, filter grade, gauge style and scale, thread (PT standard, G or NPT as options), bracket and reverse valve. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 for a 3/4 in branch feeding carton sealers, case erectors and wrapper cylinders on a packaging line: the 5 um element keeps fine debris out of directional valves while the low-pressure regulator holds a gentle, stable supply pressure for delicate clamp and pusher actions.
Filtered, regulated air for fixture clamps and swing cylinders on a CNC machining cell. The fine 5 um grade protects pilot valves and clamp cylinders from water and particulate carryover, and the reverse/check valve helps hold the set pressure if the upstream supply dips mid-cycle.
Conditioning the feed to an air-knife or blow-off manifold on a filling or drying line, where the low-pressure regulator type allows gentle, repeatable setpoints well below standard line pressure and the manual drain lets an operator clear accumulated condensate at shift checks.
Start with the port step: this unit is the size-600, G3/4 frame, the largest in the GFR range, so match it to lines where 3/4 in piping is already in place and let us confirm the flow curve against your demand rather than assuming from the port alone. Choose the drain deliberately: this code carries the manual drain (M), which also widens the usable regulator span versus the differential-pressure default - the exact low-pressure-type range for this unit is not published, so we will confirm it on request. The 5 um element (W) suits instruments and finer downstream components; the 40 um standard element remains the choice for general shop-air protection. The round psi gauge (C2) is fitted as coded; embedded square gauges and MPa or bar scales are the alternatives. Thread is G as coded, with PT standard and NPT available to order, and the bracket is included. Before ordering, send us your flow and pressure requirements - flow is published as curves, not a single rating, and we will confirm the fit.
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 characteristic curves, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure. Tell us your upstream pressure, set pressure and air demand, and we will confirm the flow curve and sizing for this size-600 unit from the datasheet on request.
The M in the code specifies a manual drain: condensate is released by operating the drain by hand, which suits attended installations on a regular check routine. The L code sets the low-pressure regulator type, intended for setpoints below the standard range; the exact adjustment span for this variant is not published in our sheet, so we confirm it on request. If you prefer automatic or differential-pressure draining, those are separate order codes in the same series.
