The AirTAC AirTAC GFR600-20MLF2W Filter Regulator PT3/4, 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 GFR600-20MLF2W is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit carries a 3/4 in PT port, a 5 um filter element (the finer of the two published grades), and a manual drain, so condensate is released by operator action rather than automatically. The embedded square gauge is fitted with a psi scale, the regulator is the low-pressure type, and the aluminium alloy bowl suits this largest frame in the series.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads to order. Flow is published as curves rather than a single rating, so we 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. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| (blank) | PT 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.

Installed on a 3/4 in compressed-air distribution main serving a production floor, it cleans the supply of water and particulate and holds a set low-pressure level for the downstream circuits.
Mounted at the inlet of a control panel or valve manifold, it feeds clean, regulated air to solenoid valves and actuators, with the psi gauge giving operators a local pressure readout.
Fitted ahead of the cylinders and air controls that drive a packaging or conveyor line, it protects the moving equipment from condensate and debris while keeping operating pressure steady.
Size 600 with a 3/4 in PT port is the largest step in the GFR range, so start here when line size and expected flow point to the top of the family; we confirm sizing against the published flow curves before you order. The 5 um element (code W) suits applications needing finer particulate removal than the 40 um standard. The manual drain keeps the bowl empty only when operated, so plan a maintenance routine around it. The square gauge reads in psi; MPa and bar scales are the other published options. PT is the standard thread, with G (BSPP) and NPT available as order options, and the mounting bracket is included.
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 this series as curves, not as a single rated figure, so we do not quote a number. Tell us your line size and demand and we will confirm the flow from the datasheet on request before you order.
The M in the code sets a manual drain: condensate collects in the aluminium bowl and is released when an operator opens the drain, so schedule regular checks. The W code selects the 5 um filter element, the finer published grade compared with the 40 um standard.
