The AirTAC GFR600C25LF2WK AirTAC Filter Regulator 1 in PT 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 GFR600C25LF2WK is an AirTAC GFR filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at a set point. This size 600 unit is built with a 1 in PT port, the optional 5 um filter element (code W), a differential-pressure drain, the low-pressure regulator type, a square gauge scaled in psi, a reverse/check valve, and the included mounting bracket. The bowl on the 600 frame is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, gauge and scale options, PT/G/NPT threads and bracket choices. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Clean, dry, regulated air to spray guns and atomizers on a paint line. The 5 um element protects finish quality from water and particulate, while the regulator holds a steady set point to the guns.
Feeding cylinders and air grippers on a packaging conveyor. The filter regulator keeps contaminants out of the actuators and holds consistent pressure so box-forming and sealing strokes repeat cleanly.
Supplying pilot air to directional control valves on a bottling filler. The 1 in PT connection serves the main header, the 5 um element guards valve seats, and the check valve holds the circuit against backflow.
Size and port set the flow path: this unit steps up to size 600 with a 1 in PT connection for larger air lines, so match the port step to your piping and demand. Drain choice matters: differential-pressure drain (this unit) removes condensate as the pressure differential builds, while automatic and manual drains are order options. Filtration here is the 5 um element instead of the 40 um standard. The regulator is the low-pressure type; its exact adjustment range is not published for this variant, so confirm it with us. The square gauge is scaled in psi (MPa and bar scales are options), a reverse/check valve is fitted, and the bracket is included. PT is the standard thread; G and NPT are order options. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 a number here. Send us your line size and air demand and we will confirm the flow from the datasheet on request before you order.
The W code selects the optional 5 um filter element instead of the 40 um standard, for finer protection of downstream tools and valves. The L code selects the low-pressure regulator type; its exact adjustment range is not published for this variant, so confirm it with us before ordering.
