The AirTAC GFR600C20LF2WT AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet 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 GFR600C20LF2WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This 600-size unit is built around a 3/4 in NPT port, and its W code specifies the fine 5 um filter element rather than the standard 40 um. The regulator is the low-pressure type, so it is intended for circuits that run below the standard adjustment band - the exact range for this variant is not published, so ask us to confirm it against your set pressure. A differential-pressure drain bleeds collected condensate automatically as the pressure differential builds, the embedded square gauge reads in psi, and the metal bowl (aluminium alloy at size 600) with the included mounting bracket suits fixed industrial installation. No reverse/check valve is fitted.
This is a genuine AirTAC part in the largest of the four GFR sizes (200, 300, 400, 600), each stepping up in port and flow capacity. Across the family you can order the 40 um standard element or the 5 um W option, differential-pressure, automatic or manual drains, square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request before you order.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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 metal stamping plant runs its pneumatic clamps and hold-downs from a circuit held below the standard regulator band. This low-pressure-type filter regulator cleans the plant air to 5 um and holds the reduced set pressure the clamps were designed around, with the psi gauge giving operators a direct read at the drop.
On a carton packaging line, the gating and diverting cylinders run continuously off a 3/4 in main. This unit filters water and fines out of the supply before they score the cylinder bores, regulates the line to the pressure the gate actuators need, and the differential-pressure drain keeps condensate moving out without a daily walk-round.
A workshop test bench that pressure-checks pneumatic assemblies needs clean, finely set air below standard line pressure. The 5 um element protects the bench's reference instruments, the low-pressure regulator trims the set point, and the psi square gauge lets the technician set and verify the test pressure directly.
Size up GFR units by port step against the air demand of the circuit: 200 through 600, with this unit at the 3/4 in NPT top of the published range. Choose the drain to match attendance: differential-pressure (this unit) drains itself with flow, automatic drains on a schedule of its own, and manual needs an operator. Pick the element by cleanliness need - 40 um standard protection or the 5 um W code fitted here for finer downstream air. Gauge scale (MPa, psi or bar - this unit reads psi), thread family (PT standard, G and NPT as order options) and the bracket are all specified at ordering. Flow is published as curves, not a single rating, so send us your application's demand and we will confirm sizing against the datasheet before you order.
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 there is no one figure we can quote here. Tell us your operating pressure and air demand and we will confirm the sizing against the datasheet on request before you order.
W is the fine-filtration option: a 5 um element instead of the 40 um standard, chosen where downstream valves and cylinders need cleaner air. The L code makes the regulator the low-pressure type, intended for circuits set below the standard adjustment band; the exact range for this variant is not published, so we confirm it against your set pressure on request.
