The AirTAC AirTAC GFR600C25F2WGK Filter Regulator G1 (1 in) 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 AirTAC GFR600C25F2WGK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit carries a G1 (1 in) port, a 5 um filter element (code W, one step finer than the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the supply is lost. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the aluminium alloy bowl is fitted for this 600 size. 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 port options from 1/8 in up to 1 in, G (BSPP) or NPT threads to order, 40 um or 5 um elements, differential-pressure, automatic or manual drains, MPa, psi or bar gauge scales, and an optional reverse/check valve. Flow 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.

Installed at a 1 in take-off from a factory compressed-air ring main, it filters water and scale from the header supply and holds a steady regulated pressure for the whole downstream section of the plant.
Feeding the air lines of a CNC machining cell, it conditions the supply to valves, clamps and tool changers, with the check valve holding the circuit's pressure if the shop air is shut off mid-cycle.
Mounted on the air drop feeding a packaging and palletising line, it removes condensate and fine particulate before pneumatic cylinders and diverters, and keeps line pressure stable as multiple actuators cycle.
Start with the port step: this unit is the size 600 body with a G1 (1 in) G-thread port, the largest step in the GFR range, so match it to the main line size feeding the section of the plant it will supply. Choose the element against the air quality you need: the 5 um (W) element fitted here suits general protection of valves, cylinders and tools where the standard 40 um grade is too coarse; a 40 um unit is the lower-cost choice where only bulk protection is needed. Drain type matters: this configuration uses the differential-pressure drain, which discharges condensate automatically as the element loads; an automatic drain (A) drains on a cycle, and a manual drain (M) requires an operator to open it. The square gauge here reads in psi; MPa and bar scales are also available, and an external round gauge is an option. G (BSPP) is ordered as shown; NPT is available to order, and PT is the catalogue standard. A bracket is included for panel or wall mounting.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm the flow curve and datasheet figures against your required flow 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 family as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow curve and datasheet figures for this size 600 unit against your required flow before you order.
The W code in the model gives the 5 um element, one step finer than the 40 um standard, for better protection of downstream valves, cylinders and tools. The drain is the differential-pressure type, which discharges condensate automatically as the element loads; automatic (A) and manual (M) drains are available on other configurations if you prefer a different drainage behaviour.
