The AirTAC GFR60020LC2WGK AirTAC Filter Regulator G3/4, 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 GFR60020LC2WGK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/4 (BSPP) port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, a low-pressure regulator type, an external round gauge scaled in psi, and a built-in reverse/check valve that holds the downstream setting if upstream supply is lost. The aluminium alloy bowl on this size suits installations where a polycarbonate bowl is not preferred.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, standard or low-pressure regulation, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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.

Spray booths and finishing guns run at reduced pressures where element cleanliness matters. This unit filters supply air to 5 um, regulates at low pressure, and the check valve keeps the setting stable if the shop supply dips.
Packaging lines with pneumatic cylinders and sealers need clean, regulated air at moderate flow. The G3/4 port suits a main drop feeding several stations, and the differential-pressure drain keeps condensate moving without operator attention.
Bench rigs and lab automation need fine (5 um) filtration and gentle low-pressure regulation for sensitive instruments and actuators. The psi-scaled round gauge gives a direct readout, and the check valve holds the set point during supply interruptions.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this unit is the 600 size at G3/4. Choose the drain to suit maintenance access: differential-pressure (as fitted here) needs no operator action, automatic drains on a cycle, and manual drains only when someone opens them. Pick 40 um for general protection or 5 um (this unit) where downstream valves and actuators need finer air. The low-pressure regulator type is intended where working pressures sit below the standard range - the exact adjustment range for the low-pressure type is not published, so confirm it with us. Gauge scale (MPa, psi or bar - this unit is psi), PT versus G versus NPT thread, and bracket provision are all decodable choices.
Because flow is published as curves rather than a single rated figure, we cannot quote one number here. Send us your application details and we will confirm sizing from the datasheet before you order.
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 filter-regulator flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your application needs, and we will confirm from the datasheet whether this G3/4, size-600 unit is correctly sized before you order.
K means a reverse (check) valve is fitted. If the upstream supply fails, the valve holds pressure downstream so the regulator setting and any stored air are retained. It is an order option on GFR units - this configuration includes it, together with the 5 um (W) element, low-pressure regulator type and psi-scaled round gauge.
