The AirTAC GFR60025LF2WGK AirTAC Filter Regulator G1 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 PT1" 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 GFR60025LF2WGK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for a G1 (1 in) port with G (BSPP) thread. This configuration carries the 5 um filter element (code W) instead of the 40 um standard, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and a reverse/check valve that holds the downstream circuit when the supply is cut. The L code makes it the low-pressure type, and the fitted embedded square gauge reads in psi for direct adjustment at the setpoint. Because this is the 600 size, the bowl is aluminium alloy rather than the polycarbonate used on the smaller frames.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional G or NPT thread in place of the PT standard, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, and gauge scale options in MPa, psi or bar. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application on request.

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.

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 low-pressure air to the wrapper and sealing stations of a packaging machine, with the 5 um element protecting the downstream valves and the check valve holding the circuit during a supply drop.
Sits ahead of large pneumatic actuators on a process skid, removing water and fine particulate from the plant air and holding a stable low-pressure setpoint read directly off the psi gauge.
Supplies the blow-off nozzles and hold-down clamps on a conveyor line, where the differential-pressure drain clears condensate as the element loads and the aluminium bowl stands up to continuous duty at the 1 in port size.
Start with the size and port: the 600 frame with its G1 (1 in) connection is the largest step in the G-series, so match it against the pipe size and the flow your line needs - we can confirm the flow curve against your demand before you order. Choose the drain type next: this unit uses the differential-pressure drain (the default), which discharges condensate on a pressure-differential signal; automatic and manual drains are available on other configurations if you prefer a timed or hands-on approach. The 5 um element (code W) suits circuits that need finer particulate control than the 40 um standard; note that finer filtration trades against a higher differential across the element. The square gauge here reads in psi - MPa and bar scales exist if your team works in those units. The G thread is a catalogue option ordered in place of the PT standard, and NPT is also available. The L code marks this as the low-pressure type; its exact regulation range is not published in the catalogue, so confirm it with us against your setpoint. Finally, flow for this series is published as curves, not a single rated figure - send us your application details and we will confirm sizing on request.
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 flow for the G-series as curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your line pressure, setpoint and air demand and we will confirm the flow curve and sizing from the datasheet on request.
The L marks the low-pressure regulator type, intended for circuits set below the standard range; the exact range for the low-pressure type is not published in the catalogue, so confirm it with us against your setpoint. The F2 code means the fitted embedded square gauge reads in psi - MPa and bar scales are available on other configurations, and an external round gauge can be ordered as an option.
