The AirTAC GFR60025LF2T 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 GFR60025LF2T is a size 600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is the low-pressure type with a 1 in NPT port, a 40 um standard filter element, and a differential-pressure drain in the aluminium alloy bowl, which opens automatically as the bowl fills so the unit keeps working without manual attention. The embedded square gauge is fitted and reads in psi, so operators can check and adjust setpoints at a glance, and the mounting bracket is included for panel or wall fixing.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element option, alternative gauge scales, and PT or G thread variants. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

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, regulated air to the large-bore cylinders and air cushions on end-of-line palletizing equipment that runs at reduced setpoints, with the psi gauge letting maintenance set the line pressure directly.
Supplies cleaned, pressure-limited air to air-knife nozzles over a bottling or canning conveyor, where the 1 in port serves the high-volume low-pressure circuit and the differential-pressure drain keeps condensate moving out during continuous shifts.
Regulates supply to the big double-acting actuator on a sluice or penstock valve, where the low-pressure type suits the reduced setpoint and the aluminium bowl and included bracket stand up to plant-room mounting.
Start with the port and size: this unit steps up to 1 in NPT on the size 600 body, the largest in the GFR range, so it suits lines with substantial air demand where smaller ports would restrict supply. Because flow is published as curves rather than a single rating, send us your demand figures and we will confirm the right size before you order. Choose the drain to match the installation: the differential-pressure drain fitted here is the default and suits continuous operation; automatic drain (code A) suits unattended duty, and manual drain (code M) suits intermittent use. The 40 um element fitted here is the standard grade; specify code W for the 5 um element where finer filtration is needed. The square gauge reads in psi; MPa and bar scales are also available. Thread is NPT here; PT is the catalogue standard and G (BSPP) is an order option. A bracket is included; on some GFR sizes code J deletes it.
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 performance curves rather than a single rated number, so we do not quote a figure here. Send us your line pressure, setpoint and air demand and we will confirm the flow from the datasheet and check the sizing against your application before you order.
The L marks the low-pressure type of regulator, intended for reduced downstream setpoints; the exact adjustment range for this type is not published in the standard tables, so we confirm it on request. The drain is the differential-pressure type (no drain letter in the code): it bleeds condensate out of the aluminium bowl automatically as pressure differential builds, with no manual draining needed during normal running.
