The AirTAC GFR60020MLF2WG AirTAC Filter Regulator G3/4, 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 GFR60020MLF2WG is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G3/4 (BSPP) port, a fine 5 um filter element, a manual drain for the bowl, and the low-pressure regulator type for circuits that run at reduced set pressures. A square pressure gauge scaled in psi is fitted so the set pressure can be read directly, and a mounting bracket is included for panel or wall fixing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge and thread options. Flow figures are published as curves rather than a single rating, 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. 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Conditioning the air feed to clamp cylinders on a fixture line: the 5 um element keeps fine contamination out of the clamping valves while the low-pressure regulator holds the reduced holding pressure the clamps are set for.
Feeding filtered, regulated air to the pusher and divertor cylinders along a packaging conveyor, with the square psi gauge letting the line technician read and hold the set pressure the actuators were sized around.
Conditioning the 3/4 inch main drop that feeds a CNC router's tool-change and hold-down circuits, with the aluminium bowl and bracket suiting a fixed machine-side installation and manual draining during scheduled stops.
Size 600 with a G3/4 port is the largest step in the GFR range, so start here when your line volume points to 3/4 inch piping; step down to 300 or 400 if the flow curves show a smaller size is sufficient. The 5 um element (code W) suits downstream equipment that needs finer filtration than the 40 um standard; the manual drain means an operator opens the drain periodically rather than relying on an automatic or differential-pressure drain. The square gauge is scaled in psi, with MPa or bar scales and an external round gauge available as alternatives. The G thread is BSPP; PT is the standard thread and NPT is an order option. The low-pressure regulator type is intended for reduced set pressures - confirm the exact adjustment range against your setpoint before ordering. We confirm flow from the datasheet on request, because it is published as curves rather than a single rating.
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. Send us your line pressure, set pressure and expected air demand and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code selects a manual drain: an operator opens the drain on the aluminium bowl to discharge collected water, rather than the bowl draining automatically or by differential pressure - a good fit where draining can be done at scheduled stops. The L in the code selects the low-pressure regulator type, intended for reduced set pressures; its exact adjustment range is not published in the standard table, so confirm it against your setpoint with us on request.
