The AirTAC GFR60025LF2W AirTAC Filter Regulator PT1, 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 GFR60025LF2W is a size-600 filter regulator: it removes water and particulate from compressed air and holds a stable downstream pressure in one body. The L in the code marks the low-pressure regulator type, the W marks the fine 5 um filter element, and the F2 gives you the embedded square gauge reading in psi. The 25 position decodes to a PT1 (1 inch) port, and the differential-pressure drain bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough - no daily manual draining on a line this size.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for this unit is published as curves rather than a single rating, so ask us to confirm the datasheet figures against 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.

| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (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. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

Installed at the 1 inch main drop feeding a packaging hall, it strips water and fine dirt from the header air and holds a steady low set pressure for the case sealers, tapers and labelers downstream.
Mounted where a conveyor system branches off the main line, it conditions the air driving gate and diverter cylinders, with the 5 um element protecting the small control valves that cycle them.
Set into a process line that runs actuators or air tools at reduced pressure, the low-pressure regulator type holds the lower set point while the differential-pressure drain keeps condensate off the circuit without operator attention.
Size 600 with a 1 inch PT port is the large-flow end of the GFR range - step up or down a size if your line flow or piping changes. This configuration carries the 5 um (W) element, the right choice when downstream valves, cylinders or instruments want finer air than the 40 um standard element delivers. The low-pressure (L) regulator type suits circuits that hold set pressures below what a standard GFR is built around; the exact set-pressure range for the low-pressure type is not published in the catalogue, so confirm it with us before ordering. The square gauge is fitted and reads in psi; MPa and bar scales and an external round gauge are the alternatives. Differential-pressure drain is standard here, with automatic (A) and manual (M) drains available. Thread is PT as standard; G and NPT are order options, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated figure, so send us your line flow and pressure requirements and we will confirm the right size from 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 the GFR family as performance curves, not as a single rated number, so we do not quote a figure here. Tell us your line flow and working pressure and we will confirm the sizing for this 1 inch unit from the datasheet on request.
L marks the low-pressure regulator type, built for circuits that hold lower set pressures than the standard GFR - the exact set-pressure range is not published, so confirm it with us. W marks the fine 5 um filter element instead of the 40 um standard. This unit also carries a square psi gauge, a differential-pressure drain and a PT1 (1 inch) PT thread.
