The AirTAC GFR600C25LNWT AirTAC Filter Regulator NPT1 Low-Pressure 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 GFR600C25LNWT is an AirTAC GFR filter regulator: water and particulate filtration plus pressure regulation combined in a single size-600 body with a 1 in NPT port. This configuration carries the 5 um filter element (code W) for finer air cleaning than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and the low-pressure regulator type for circuits set well below standard line pressure. No gauge is fitted as supplied, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, filter grade and gauge. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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.

Feeds clamp and fixture cylinders on a CNC machining cell, filtering machining-air moisture and particulate at 5 um while the low-pressure regulator holds the clamping circuit at the gentle setting the fixture designer intended.
Sits at the drop point feeding diverters, pushers and gate actuators on a packaging conveyor, cleaning the shop air and regulating it down for the low-pressure cylinders that handle product gently.
Installed at an overhead plant-air drop serving low-pressure air tools and blow-off stations, removing water and fine dirt before the regulator sets the reduced pressure the station needs.
Step up through the GFR sizes (200, 300, 400, 600) as your port and air demand grow; this size-600 unit takes a 1 in NPT connection for high-flow lines. Choose the drain to match the installation: differential-pressure (as here) drains only when the element loads up, automatic drains continuously, and manual suits attended points. The 5 um element (W) is the right pick where finer particulate matters; the 40 um standard grade suits general supply. Gauge and scale are selectable on regulator-equipped units, and PT is the standard thread with G and NPT as order options.
Because flow for this family is published as curves rather than a single rated figure, we do not quote a number here. Send us your application details and we will confirm sizing against the datasheet before you order. The exact regulation range of the low-pressure type is likewise confirmed on request.
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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, regulated setpoint and expected air demand, and we will confirm the sizing against the datasheet before you order.
The W in the code GFR600C25LNWT selects the optional 5 um filter element instead of the 40 um standard grade, giving finer particulate removal upstream of the regulator. The N selects no gauge fitted as supplied, and the L selects the low-pressure regulator type. The differential-pressure drain is the default for this family: it discharges collected condensate when the pressure differential across the element rises.
