The AirTAC GFR60020LF1WT AirTAC Filter Regulator NPT3/4 Low-Pressure 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 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 AirTAC GFR60020LF1WT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type with a 3/4 in NPT port, 5 um filtration (code W, finer than the 40 um standard), a differential-pressure drain on the bowl, and an embedded square gauge scaled in MPa. At size 600 the bowl is aluminium alloy, and the mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with port options from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

A fixture-clamping circuit that must run at a reduced setpoint gets filtration and pressure control in one body, with the 5 um element protecting the clamp valves from particulate carried in the shop air.
At the 3/4 in feed into a packaging line's manifold, this unit strips water and fine dirt and holds the header pressure where the machine's cylinders and actuators were set up to run.
Bench rigs and pilot rigs fed from a shop compressor benefit from the 5 um grade and a visible MPa gauge, with the differential-pressure drain clearing collected water from the aluminium bowl as the rig runs.
Size 600 with a 3/4 in port is the largest step in the GFR range; step up or down (200/300/400/600) according to the flow your line needs, and ask us to check the published flow curves against your demand before ordering. This unit is the low-pressure type, so confirm its regulation range suits your setpoint - the exact figure is not published and we will confirm it on request. Drain is differential-pressure (the default); automatic (A) and manual (M) versions exist if you prefer. Filtration is 5 um here (code W); the 40 um standard element is the alternative. The square gauge is embedded and MPa-scaled; an external round gauge with psi or bar scale is an option. Thread is NPT on this code; PT is the standard and G is also orderable. A bracket is included (J removes it).
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 family as curves, not as a single rated figure, so we do not quote a number. Send us your application's flow and pressure requirements and we will confirm the sizing from the datasheet curves on request before you order.
W is the filter grade code: this unit carries the 5 um element instead of the 40 um standard. The L in the code marks the low-pressure regulator type, whose exact regulation range is not published - we will confirm it against your setpoint on request. The unit also has a differential-pressure drain, an embedded square MPa gauge, and a 3/4 in NPT port.
