The AirTAC GFR60025LF3WT AirTAC Filter Regulator NPT1 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 GFR60025LF3WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, rated to 1.0 MPa (145 psi) inlet. This size-600 unit carries a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain and the low-pressure regulator type, with an embedded square gauge reading in bar. The aluminium alloy bowl suits this largest frame, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, standard or low-pressure regulation, and PT, G or NPT threads, all operating from -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet for your application.

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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Feeding spray and coating stations that run below standard shop pressure, where the low-pressure regulator type and 5 um element keep air clean and pressure held steady at the gun.
Supplying clean, regulated air to rollers, nip cylinders and pneumatic guides on paper, film and foil converting lines where a 1 in supply serves the whole machine.
Regulating clamp cylinders on welding and assembly fixtures that need steady low holding pressure, with the differential-pressure drain shedding condensate as air flows.
Choose the size by port and required flow: this 600 frame carries a 1 in NPT port, the largest in the range. Drain options are differential-pressure (fitted here), automatic (A) or manual (M); filtration is 40 um standard or 5 um with the W code, as on this unit. The L code selects the low-pressure regulator type instead of the standard unit. The gauge is the embedded square type with a bar scale (MPa and psi scales are alternatives), and the trailing T orders NPT threading instead of the PT standard, with a bracket 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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and allowable pressure drop and we will confirm the sizing from the datasheet on request.
L selects the low-pressure regulator type instead of the standard unit, and W selects the 5 um filter element in place of the 40 um standard. This unit also carries T for NPT thread, F3 for the square gauge with bar scale, and no drain letter, which means the differential-pressure drain.
