The AirTAC GFR600C25LNT AirTAC Filter Regulator 1 in NPT 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 GFR600C25LNT is a filter regulator: water and particulate removal plus pressure regulation in a single body, sized for 1 in NPT connections on the 600 frame. This configuration carries the standard 40 um filter element and a differential-pressure drain, and it is the low-pressure regulator type, so it suits circuits held at reduced working pressure rather than full line pressure. No gauge is fitted (code N), and the 600-size bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or manual drains, gauge and thread options, and standard or low-pressure regulation. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure 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.

Feeds filtered, reduced-pressure air to the air-knife manifold that clears debris and cooling air across glass sheets, where the low-pressure regulator type holds the knife circuit below full header pressure.
Supplies filtered air to the hold-down and blow-off jets that keep lightweight PET bottles seated on high-speed conveyor runs, with the 1 in port serving a large jet header from one preparation point.
Prepares air for the bank of quarter-turn dampers and sluice-gate actuators around a treatment train, filtering supply water out and regulating the header to the reduced pressure the actuators are set up for.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs; this unit is the 600 frame with a 1 in NPT port, the largest step in the family. Choose the drain type: differential-pressure (this unit), automatic, or manual. Choose the filter grade: 40 um standard as fitted here, or 5 um with the W code. Gauge, scale and thread (PT standard; G and NPT as order options) are decodable choices, and a bracket is included on this unit.
One honest routing note: flow in this series is published as curves, not a single rating, and the exact regulation range of the low-pressure type is not stated in the material we hold. Ask us to confirm sizing and the low-pressure range against your 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 as a single rated figure, so we do not quote a number here. Tell us your line conditions and we will confirm the flow from the datasheet curves for this 600-size, 1 in NPT unit before you order.
The L code makes this a low-pressure regulator rather than the standard type, and the N code means no gauge is supplied, so you would add your own instrumentation downstream. The exact regulation range of the low-pressure type is not published in our sheet; ask us to confirm it against your setpoint, and note a gauge version is available in the family under other codes.
