The AirTAC GFR600C25LC1WT AirTAC Filter Regulator NPT 1 in 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 GFR600C25LC1WT is a 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 around a 1 in NPT port, carries the 5 um filter element (the finer of the two catalogue grades), drains condensate by differential pressure, and is fitted with a round pressure gauge scaled in MPa. It is the low-pressure type, intended where downstream pressure must sit below the standard band; the exact adjustment range is not published, so we confirm it against your set point on request. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), the size 600 metal bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT as standard with G and NPT thread options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, embedded square or external round gauges scaled in MPa, psi or bar, and bracket options. 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.

A 1 in filtered and regulated drop feeding a paint-shop air main keeps water and fine particulate out of the spray air while holding a steady low-pressure set point for the spray guns.
Feeding tool-clamp and purge circuits on a machining cell, the unit strips condensate and fines from the mill's compressed air and regulates it to the set point the clamps require.
On a bottling hall's main conveyor run, the filter regulator conditions the air feeding stopper and gate cylinders, with the differential-pressure drain clearing condensate as line flow rises.
Size and port set the flow path: GFR600 is the largest of the four sizes, and the 1 in NPT port here suits a main air drop or a high-demand machine supply - step down to 300 or 400 if your line runs smaller ports. Drain choice matters on a filter regulator: differential-pressure (this unit) ejects condensate as flow rises, automatic drains clear the bowl without intervention, and manual drains need someone to open the bowl. This unit carries the 5 um element (code W); the 40 um standard element suits general shop air where finer filtration is not required. The round gauge here reads in MPa; embedded square gauges and psi or bar scales are catalogue options. Thread is NPT on this unit - PT is the AirTAC standard and G (BSPP) can be ordered instead. Flow is published as curves, not a single rating, so send us your demand and let us confirm sizing against the application 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 series as curves, not a single rated figure, so we do not quote a number here. Send us your line pressure, set point and air demand and we will confirm the datasheet curve and sizing for your application on request.
The W code orders the 5 um element instead of the 40 um standard, giving finer particulate removal ahead of sensitive downstream equipment. The blank drain position is the differential-pressure type, which ejects accumulated condensate as flow through the unit rises, with no manual intervention. Automatic and manual drains are catalogue alternatives if your duty suits them better.
