The AirTAC GFR600C20LC2W AirTAC Filter Regulator PT3/4, 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 GFR600C20LC2W is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one size-600 body with PT3/4 ports. This configuration carries the 5 um element (code W) for finer particle removal than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, and a low-pressure regulator type for setpoints below the standard range. It is fitted with an external round gauge scaled in psi, and the metal bowl at size 600 is aluminium alloy. A mounting bracket is included; no reverse/check valve is fitted in this version.
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, PT (standard), G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and embedded square or external round gauges in MPa, psi or bar scales. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures for your application 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.

Feeds adhesive heads that need a gentle, stable supply well below normal main-line pressure. The low-pressure regulator type sets the reduced level, the 5 um element keeps gumming debris out of the nozzles, and the differential-pressure drain sheds condensate without a daily bowl-draining routine.
Serves bench-scale reactors, spargers and pneumatic actuation on skid-mounted process equipment where a clean, low setpoint supply matters. The 5 um element protects fine metering components, the psi-scaled round gauge gives a familiar readout, and the included bracket fixes the unit to the skid frame.
Regulates the gentle air used to convey product or drive dosing gates where full line pressure would crush or over-feed. The aluminium alloy bowl suits the size-600 flow duty, the differential-pressure drain keeps moisture out of the product-contact circuit, and the PT3/4 ports match the machine's main air drop.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs - size 600 with its 3/4 in PT ports sits at the top of the range for higher-demand circuits. Choose the drain to match maintenance access: differential-pressure (this unit) bleeds condensate on pressure drop, automatic drains continuously, and manual drains only when the bowl is drained by hand. Pick the 5 um element (as fitted here) where downstream valves and cylinders need finer protection, or the standard 40 um grade for general-duty air. Select the gauge scale - MPa, psi or bar - and the thread: PT is the standard, with G and NPT available as order options. One honest note on sizing: AirTAC publishes flow for this series as curves, not a single rated number, so send us your application details and we will confirm the right size 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 there is no one l/min or SCFM number we can honestly quote. Tell us your line pressure, setpoint and the equipment you are feeding, and we will confirm the flow figures from the datasheet for this exact unit before you order.
The W code in GFR600C20LC2W selects the optional 5 um filter grade, which removes finer particles than the 40 um standard element. Choose it when the downstream valves, cylinders or process equipment are sensitive to fine contamination; keep the 40 um grade for general-duty air where the finer element is not needed.
