The AirTAC GFR600C20ALF1WTK AirTAC Filter Regulator NPT3/4, 5 um 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 GFR600C20ALF1WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation in one body. This size-600 unit carries a 3/4 in NPT port, a 5 um filter element (the finer of the two published grades), an automatic drain that expels collected condensate without manual attention, and a low-pressure regulator type. A square pressure gauge scaled in MPa is fitted, a reverse/check valve is included, and the metal bowl on this 600 size is aluminium alloy. A mounting bracket is supplied.
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, a choice of drain type, 40 um or 5 um filtration, gauge scale options and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for 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. 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.

On a cartoning or wrapping line, the combined element strips water and fine particles from the shop-air drop and the low-pressure regulator holds a gentle, stable supply to the machine's light-duty cylinders and actuators, with the automatic drain keeping the bowl clear between shifts.
A pilot-scale process skid drawing compressed air for instrumentation and sample handling benefits from the 5 um element protecting sensitive components, while the low-pressure regulation and MPa gauge let technicians set and read a careful supply pressure at the header.
At a conveyor line's gate and diverter stations, this unit filters the supply, regulates it down to the pressure the gate cylinders were designed for, and the reverse/check valve helps hold the set pressure against upstream fluctuations during continuous sorting duty.
Size and port are the first decision: step up through 200, 300, 400 and 600 as your flow demand and pipe size grow - this unit is already the largest, at size 600 with a 3/4 in NPT port. Drain type is a real choice: automatic (as fitted here) suits unattended duty, manual drain suits supervised installations, and the differential-pressure default drains only when the pressure differential calls for it. Filter grade is 40 um standard or 5 um (code W) where finer particulate protection is needed - this unit carries the 5 um element. Gauge scale can be MPa, psi or bar, and the square gauge is embedded while an external round gauge is optional. Thread is PT as standard, with G and NPT as order options; this unit is specified NPT. A bracket is included, and a reverse/check valve is fitted.
Because flow is published as curves and not a single rated figure, we cannot quote one number here - send us your application details 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 rather than a single rated figure, so we do not quote one number. Tell us your application - pipe size, downstream demand and working pressure - and we will confirm the sizing against the datasheet on request before you order.
The W in the code specifies the finer 5 um filtration grade (40 um is the standard element), and the A specifies an automatic drain that discharges condensate on its own instead of the differential-pressure default. Both are order-time choices: the same size-600 filter regulator can be specified with the 40 um element and with manual or differential-pressure draining if that suits your installation better.
