The AirTAC GFR600C25ALC2TK 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 GFR600C25ALC2TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is built for a 1 in NPT port, has an automatic drain that empties the metal bowl without daily attention, a 40 um filter element, and a low-pressure regulator for circuits that run below standard line pressure. A check valve is fitted to hold downstream pressure if the supply drops, and a psi-scale round gauge is included so the setting is visible at the unit.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for thread (PT standard, G and NPT to order), drain type, 5 um filtration, gauge style and scale. Max inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. We confirm flow and other datasheet figures on request, because flow is published as curves rather than a single rating.

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 pneumatic clamping circuit that runs below standard line pressure, this low-pressure filter regulator sets and holds the clamp pressure while the 40 um element keeps debris out of the cylinder seals. The fitted check valve holds the clamp if the shop-air supply drops.
Feeding low-pressure air knives or nozzles on a carton-sealing or labeling line, the automatic drain keeps condensate out of the nozzles without daily attention, and the 1 in NPT connection suits a plant supply main feeding several stations.
On a paint or coating line, the low-pressure regulator holds the gentle pressure atomizing guns need, the automatic drain protects the guns from water carryover, and the psi-scale gauge lets operators verify the setting at the unit.
Size and port step up with air demand: 600 is the largest GFR size and this unit carries a 1 in NPT connection, so match it to the machine's supply main. Choose the drain to suit access: automatic (fitted here) suits units mounted high or in awkward spots, manual suits attended installations, and differential-pressure draining is the catalogue default. The 40 um element is the standard grade; specify code W for 5 um where finer particulate removal matters. This is the low-pressure (L) type, so tell us the downstream pressure you need and we will confirm suitability before you order. Thread options are PT (standard), G and NPT (this unit is NPT), and a mounting bracket is included.
Flow is published as curves, not a single rating, so ask us to confirm sizing 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 GFR flow as curves, not a single rated figure, so we do not quote a number here. Send us your application's air demand and line pressure and we will confirm against the datasheet whether the 600 size with a 1 in NPT port is correctly sized before you order.
It marks the low-pressure regulator type. This unit is built for circuits that run below standard line pressure; its exact regulation range is not published in the catalogue, so tell us the downstream pressure you need and we will confirm suitability. Max inlet pressure remains 1.0 MPa (145 psi).
