The AirTAC GFR60020MLF2WT AirTAC Filter Regulator NPT3/4 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 GFR60020MLF2WT is a size-600 GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for 3/4 in NPT ports, carries a 5 um filter element (code W) for finer filtration than the standard 40 um grade, and uses a manual drain on the bowl, so condensate is released by hand rather than automatically. It is the low-pressure type, and the embedded square gauge fitted to the unit reads in psi. 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 line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include drain type, filter grade, gauge style and scale, thread form (PT standard, G and NPT to order) and bracket choice. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will 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.

| 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. |

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 branch off the main plant air header, it strips water and particles and holds a steady low-pressure supply to a production cell, with the psi gauge giving operators a local pressure readout.
Feeding cylinders and air-driven grippers on a packaging or case-erector line, the 5 um element protects valve seals from fine debris while the regulator sets the lower pressure those actuators are designed for.
On a test bench or laboratory rig where instruments need clean, gently regulated air, the low-pressure type regulator and fine 5 um filtration keep the supplied air stable, with manual draining between test sessions.
Size 600 is the largest step in the GFR range, and here it is paired with 3/4 in NPT ports - the right choice when your line runs at higher flow through 3/4 in piping. Because published flow is shown as curves rather than one rated figure, tell us your application and we will confirm sizing against the datasheet before you order. The 5 um element (code W) suits points of use that need finer particle removal than the standard 40 um grade; the manual drain suits installations where an operator can bleed the bowl as part of routine checks, while automatic or differential-pressure drains are available in the series for unattended duty. This unit is the low-pressure type - confirm its adjustment range with us, as the exact figure for the low-pressure version is not published. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread for the series, with G (BSPP) and NPT as order options, and a mounting bracket is included with this unit.
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 figure here. Tell us your inlet pressure and demand and we will confirm the datasheet curve values for this exact model on request before you order.
The manual drain (code M) means condensate collected in the bowl is released by hand during routine checks, rather than automatically - a simple choice where the unit is inspected regularly. The W code sets the filter element to 5 um instead of the standard 40 um, giving finer particle removal for sensitive downstream equipment.
