The AirTAC GFR60020LF1WTK AirTAC Filter Regulator NPT3/4, 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 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 GFR600 series combines water and particulate filtration with pressure regulation in a single filter-regulator body, so one unit cleans the air and holds your downstream pressure where the process needs it. This configuration is the 600 size with a 3/4 in NPT port, a fine 5 um filter element, the low-pressure regulator type, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element rises. It ships with an embedded square MPa gauge for direct setting, a built-in reverse/check valve, and a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 inch, manual or automatic drain options, 40 um or 5 um elements, gauge scale choices, and G or NPT thread variants. 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.

| 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.

Feeding cleaned, regulated air to a 3/4 in main supplying pneumatic presses and clamping fixtures, with the 5 um element protecting cylinder seals and valve seats from fine particulate.
A filter-regulator station ahead of a robotic assembly cell, holding a stable low supply pressure to actuators while the differential-pressure drain keeps condensate out of the circuit.
Supplying fine-filtered, low-pressure air to process instruments and pneumatic transmitters, where the 5 um element and check valve protect sensitive control components.
Size the unit by the flow your line needs: the 600 size with its 3/4 in port sits at the top of the GFR range for higher-demand circuits. The 5 um element (code W) suits instruments, valves and paint work that need finer air than the standard 40 um element; the differential-pressure drain keeps condensate off the element without a manual routine. The low-pressure type is intended for circuits set below the standard regulator range, and the square MPa gauge is fitted as standard - psi or bar scales and an external round gauge can be ordered instead. NPT is the thread on this code; G (BSPP) is the catalogue alternative. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering.
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 curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow figures from the datasheet for this exact 600-size unit before you order.
The L in the code marks the low-pressure regulator type, intended for circuits set below the standard range, and W marks the fine 5 um filter element instead of the standard 40 um. The exact low-pressure adjustment range is not published on the sheet we work from, so we confirm it on request.
