The AirTAC GFR60025LF1WT AirTAC Filter Regulator 1 in NPT, Low-Pressure is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" 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 GFR60025LF1WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type with a 5 um filter element (the finer of the two published grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square gauge scaled in MPa so the set pressure is visible at a glance. It is threaded NPT1 (1 in) and carries a maximum inlet pressure of 1.0 MPa (145 psi), with an operating temperature of -5 to 70 C (non-freezing). The size-600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um elements, standard or low-pressure regulation, square (MPa/psi/bar) or optional external round gauges, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Air-prep for low-pressure clamping fixtures on a CNC or manual machining line: the 5 um element protects fixture cylinders from water and swarf-carrying condensate, while the regulator holds a gentle, repeatable clamp pressure that will not mark finished workpieces.
Feeding air knives or blow-off nozzles that clear dust and moisture from cartons and film on a packaging conveyor. The low-pressure regulator trims the jet to what the product tolerates, and the differential-pressure drain keeps condensate out of the nozzle ring.
Supplying positioner and actuator air to diaphragm-controlled valves on a water or wastewater treatment skid, where the 5 um grade and visible MPa gauge help keep the valve pilot circuit clean and its set point verifiable during rounds.
Step up through the GFR sizes (200/300/400/600) as your required flow and port size grow; this unit sits at the top of the range with a 1 in NPT port. Choose the drain to suit access: differential-pressure (fitted here) needs no operator action, automatic drains even at no-flow, and manual suits attended installations. The 5 um element fitted here is the finer published grade; 40 um is the standard alternative. Gauge scale (MPa/psi/bar), thread (PT standard, G and NPT as order options) and bracket are all decodable choices. Because flow for this series is published as curves rather than one rated figure, 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure, set pressure and expected air demand and we will confirm the flow data from the datasheet for this exact model on request.
In the code GFR60025LF1WT, W selects the 5 um filter element (the finer of the two published grades; 40 um is standard) and F1 selects the embedded square gauge scaled in MPa. The L marks the low-pressure regulator type, and the trailing T selects the NPT thread; with no drain letter, the differential-pressure drain is fitted.
