The AirTAC GFR60025LF2G AirTAC 1 in Filter Regulator, 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, and this GFR60025LF2G is the size-600, 1-inch configuration for lines that need both functions at high flow capacity. The L in the code marks the low-pressure regulator type, the F2 fits an embedded square gauge reading in psi, and the blank drain position gives the differential-pressure drain, which bleeds condensate from the aluminium alloy bowl as the pressure differential changes during operation. A mounting bracket is included for secure panel or frame installation.
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 standard or 5 um (W) filtration, square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Rated flow for this series 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 gripper and clamp actuators on a bottle-filling line, where the low-pressure regulator type holds a gentle setpoint and the 1 in port serves the main drop from the plant ring main.
Supplies the air cylinders that divert, stop and index product on a high-volume conveyor system, with the 40 um element keeping scale and pipe debris out of valve seats and the differential-pressure drain clearing condensate as the line breathes.
Prepares air for the pneumatic actuators on a treatment-plant valve manifold, where the low-pressure regulator suits large diaphragm actuators, the psi gauge gives operators a familiar readout, and the included bracket secures the unit beside the manifold.
Start with the port step: this unit is size 600 with a 1 in G-thread connection, the largest in the GFR range, so check your line size and required flow before stepping down. Choose the drain to match duty: differential-pressure (this unit) suits steady running, automatic (A) drains without operator attention, and manual (M) gives hands-on control. Filter grade is 40 um standard here; specify W for 5 um where finer protection is needed. The low-pressure (L) regulator type is selected where the circuit runs below standard regulator settings - its exact adjustment range is not published, so confirm it with us against your setpoint. Gauge scale is psi on this unit; MPa or bar scales are available. Thread is G (BSPP) as coded; PT is the standard option and NPT can be ordered. Flow for the series 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 flow for the GFR600 series as curves rather than a single rated figure, so no single number would be honest. Send us your line pressure, setpoint and expected air demand, and we will confirm the flow curve and datasheet figures for this exact model on request before you order.
The L in GFR60025LF2G marks the low-pressure regulator type, intended for circuits that run at lower regulated pressures than the standard version. Its exact adjustment range is not published in the catalogue data we hold, so confirm your setpoint with us and we will verify suitability on request. Everything else decodes normally: 1 in G thread, 40 um filtration, differential-pressure drain and a square psi gauge.
