The AirTAC GFR60020LNWT 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 GFR60020LNWT is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size-600 unit carries a 3/4 in NPT port, the low-pressure regulator type, and a 5 um filter element (code W) for finer protection of downstream components than the standard 40 um grade. Condensate is removed through the differential-pressure drain, and the aluminium alloy bowl suits this largest frame in the series. No gauge is fitted (code N), so regulation is set by the adjuster and checked with your own instrumentation.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options in PT (standard), G (BSPP) and NPT, 40 um or 5 um filtration, and drain choices; brackets are included on this configuration. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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. |
| (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.

Feeds filtered, regulated air to case packers and carton-sealing cylinders on a packaging line, with the 5 um element protecting valve spools from particulate carryover.
Serves as the single filter-regulator point for pneumatic pushers and diverters on a conveyor system, conditioning air before it reaches the directional valves.
Conditions shop air for lab benches and pneumatic test rigs where low-pressure regulation and fine 5 um filtration keep sensitive instruments and fixtures supplied with clean air.
Size and port are the first choices: this unit is size 600 with a 3/4 in NPT port, the largest frame, so step down to 200/300/400 if your line runs smaller ports or lower air demand. The 5 um element (W code) suits air tools, valves and instruments that need finer particulate removal than the standard 40 um grade; the differential-pressure drain bleeds condensate automatically as flow passes through, with no manual draining in normal operation. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also orderable. A bracket is included for panel or wall fixing, and no gauge is fitted - add external gauges separately if you want a visual setpoint. Because flow is published only 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. 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 here. Tell us your application and we will confirm the flow and datasheet figures on request before you order.
The W code in GFR60020LNWT selects the optional 5 um filter grade instead of the standard 40 um element, for finer protection of downstream equipment. The N code means no gauge is fitted; regulation is set at the adjuster, and external gauges can be added separately if you want a visual indication.
