The AirTAC GFR600C25ALC3T 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 AirTAC GFR600C25ALC3T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 in NPT port, an automatic drain that bleeds collected condensate from the aluminium-alloy bowl without manual attention, a 40 um standard filter element, and the low-pressure regulator type. A round external gauge scaled in bar is fitted so the set pressure is visible at the unit, and the 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, a choice of automatic, manual or differential-pressure drains, a 5 um (code W) element option, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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 drop from a factory compressed-air ring main, it filters bulk water and scale from the header supply and holds a steady low set pressure for the downstream distribution leg.
Feeding the cylinder and air-circuit bank on a carton-forming conveyor line, where clean, moisture-bleeding supply and a stable low regulated pressure keep clamp and pusher strokes consistent through the shift.
Mounted as the first conditioning stage in a machine's pneumatic control panel, protecting directional valves and logic circuits from condensate and debris while the bar-scaled gauge gives operators a visible set point.
Start with the port step: size 600 with a 1 in port is the largest GFR frame, so match it to the line size and the air demand of the circuit; if your demand sits well below the capacity of a 1 in line, a smaller size may be the more economical choice. Choose the drain to suit access: automatic (this unit) suits installations that are not checked daily, manual suits attended stations, and differential-pressure drain is the default. The 40 um element is standard; specify the W code for the 5 um grade where downstream equipment needs finer filtration. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are selected at ordering, and the bracket is included on this unit. Flow for this family is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet 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 this family as curves rather than a single rated figure, so we do not quote one number. Send us your line conditions and air demand and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A in the code specifies an automatic drain, which discharges collected condensate from the bowl without operator attention - useful for elevated or infrequently visited installations. The same GFR600 frame can be ordered with a manual drain or the differential-pressure drain instead if your maintenance routine suits it.
