The AirTAC GFR60025LF1T 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 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 GFR60025LF1T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the low-pressure type (code L) with a 1 in NPT port, the standard 40 um filter element, a differential-pressure drain in the bowl, and an embedded square gauge scaled in MPa. At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, threads, drain types, 40 um or 5 um filtration, gauge styles and scales. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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, low-pressure regulated air to clamping cylinders on an assembly press, with the square gauge letting operators verify setting at a glance and the differential-pressure drain clearing condensate as air flows.
Conditions the air supply to spray-gun atomizing circuits that run at reduced pressure, where the 40 um element keeps water and grit out of the gun and the low-pressure type matches the lower setting the booth needs.
Supplies filtered, regulated low-pressure air to air-knife nozzles that strip rinse water from bottles on a conveyor, with the aluminium bowl and differential drain handling condensate in a continuous-flow section.
Step up through sizes 200, 300, 400 and 600 to match the port and the flow your line needs - this unit is the 600 size with a 1 in NPT port. The L code makes it the low-pressure type, so confirm the working range suits your circuit before ordering. Drain options are differential-pressure (this unit), automatic (A) or manual (M); filtration is 40 um standard or 5 um with the W code; the square gauge is fitted here with an MPa scale, and an external round gauge with MPa, psi or bar scales is optional. Thread is NPT on this model; PT is the standard and G (BSPP) is an order option. A bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, setting and expected air demand and we will confirm the flow curve and datasheet figures for this exact model on request.
L marks the low-pressure type of the GFR regulator section. It is intended for circuits that run at reduced settings rather than the standard range. The exact adjustment range for the low-pressure type is not published in our data sheet, so confirm your required setting with us on request before ordering.
