The AirTAC GFR600C25MLC3T 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 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 GFR600C25MLC3T is a size-600 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration is built around a 1 in NPT port for high-flow supply lines, with a manual drain bowl in aluminium alloy (size 600 bowls are metal, not polycarbonate), a 40 um standard filter element, and the low-pressure regulator type. An external round gauge with a bar scale is fitted, and the mounting bracket is included, so the unit can be secured to a panel or frame at install.
This is a genuine AirTAC part from the GFR family, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread choices of PT (standard), G and NPT, manual, automatic or differential-pressure drains, and a 5 um element option (code W) in place of the 40 um standard. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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. 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.

On a 1 in branch feeding pneumatic spray and drying stations in an automotive paint shop, this filter regulator strips water and pipe scale from the plant air and holds a steady low supply pressure to the booth equipment, with the manual drain bled during shift checks.
A bottling plant can use this unit at the head of the 1 in air drop serving conveyor stops, gates and pusher cylinders, filtering the compressed air and regulating it to the pressure the line actuators were designed for, with the included bracket mounting the unit at the line frame.
In a chemical pilot plant, this filter regulator on the skid's 1 in instrument-air feed removes moisture and particulates and lets technicians set a low, stable supply pressure for air-operated valves and sample handling, reading the fitted bar gauge during commissioning.
Start with the port step: this unit is the size-600 frame with a 1 in NPT connection, the largest in the GFR range, so match it to your main supply line diameter and expected demand. Choose the drain to suit access: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl; automatic and differential-pressure drains are available on other codes for unattended drops. The filter grade here is the 40 um standard element; if downstream equipment needs finer protection, the 5 um (W) version is the decodable alternative. The fitted gauge is the external round type with a bar scale; square embedded gauges and MPa or psi scales are the other catalogue choices. Thread is NPT on this code, with PT (standard) and G available as order options, and the bracket is included. One honest note on sizing: AirTAC publishes flow as curves, not a single rated number, and the exact regulation range of the low-pressure type is not stated in the published data, so ask us to confirm flow and set-pressure figures 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 this series as curves rather than a single rated figure, so we do not quote a number. Tell us your line size and demand and we will confirm the datasheet flow curve and sizing for your application on request before you order.
This code is ordered with a manual drain: condensate collected in the aluminium alloy bowl is released by hand, which suits attended installations on a regular check routine. The catalogue also offers automatic (code A) and differential-pressure (blank) drains on GFR units for drops that are not visited daily - those are separate order codes, not field changes.
