The AirTAC GFR60025LC2TK AirTAC Filter Regulator 1 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 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 GFR60025LC2TK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This size-600 unit is specified with a 1 in NPT port, the standard 40 um filter element, a differential-pressure drain, and the low-pressure regulator type. The C2 gauge code adds a round pressure gauge reading in psi, the K code fits a reverse (check) valve, and the bracket is included for panel or wall mounting. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Because this is the 600 size, the drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, manual, automatic or differential-pressure drains, a 5 um (W) filter element option, gauge and scale choices, G/NPT thread options and low-pressure variants. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures 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.

On a stamping or forming press that runs its air circuit at reduced pressure, this filter regulator cleans the supply, holds the setpoint for the counterbalance and clamping circuits, and the check valve holds downstream pressure if the upstream line is vented.
At a loom shed's 1 in branch drops, the unit strips condensed water and pipe scale before the weaving air supply, and the low-pressure type regulator suits circuits that run below standard plant pressure.
Feeding the pneumatic pushers and gate cylinders on a bottling conveyor line, the filter regulator keeps moisture and debris out of the valves while holding a steady pressure so cylinder stroke timing stays repeatable.
Start with the port and size step: the 1 in NPT connection on this 600-series body suits lines plumbed in 1 in pipework, and the next size down steps to 3/4 in if your circuit is smaller. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. This unit is the low-pressure regulator type; confirm the setpoint you need with us so we check it against the datasheet. The drain here is differential-pressure, which bleeds the bowl automatically as pressure drops across the element; automatic (A) and manual (M) drains are the other catalogue choices. The standard element is 40 um, with a 5 um (W) element available where finer filtration is needed. The C2 code fits a round gauge reading in psi; the embedded square gauge is standard and MPa or bar scales can be ordered. Thread is NPT here, with PT as the standard and G (BSPP) as further order options, and the mounting bracket is included.
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 GFR series as curves rather than a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request before you order.
C2 specifies a round pressure gauge reading in psi fitted to the regulator (the embedded square gauge is the standard alternative, with MPa or bar scales available). K means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply is lost. This unit also carries the L code for the low-pressure regulator type.
