The AirTAC GFR60025ALF2 AirTAC Filter Regulator PT1 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 automatic 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 GFR60025ALF2 is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1-inch PT port, the 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, and a low-pressure regulator type for circuits that operate at reduced regulated pressures. The embedded square gauge is fitted with a psi scale, and the aluminium alloy bowl is the material used at size 600.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), a 5 um element option, gauge scale options and G or NPT thread variants. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures 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.

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.

A workholding or light-clamping press circuit that holds a reduced regulated pressure benefits from filtered air and stable regulation in one body, with the psi gauge giving operators a direct setpoint readout.
Carton-forming and case-sealing cylinders on a packaging line draw filtered, regulated air at a low setpoint; the automatic drain keeps condensate off the valves during continuous shifts.
Loom and spinning-frame air jets and cylinders need water and particulate stripped out before use; this unit conditions and regulates the supply at the reduced pressures those machines run at.
Size 600 with a 1-inch PT port is the step to take when your line's required flow sits at the top of the GFR range - match the port step to the flow curve for your conditions, and we will confirm the curve figures on request. The automatic drain suits unattended duty; choose manual drain if you prefer controlled, scheduled blowdown. The 40 um element is the standard grade; the 5 um (W) element is the option where finer particulate removal is needed. This is the low-pressure (L) regulator type, intended for circuits holding reduced regulated pressures - confirm the exact range against your setpoint with us before ordering. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread; G (BSPP) and NPT are order options. A mounting bracket is included.
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, not as a single rated figure, so we do not quote a number here. Send us your line pressure, setpoint and expected air demand and we will confirm the flow figures from the datasheet on request before you order.
The L code marks the low-pressure regulator type, intended for circuits that hold reduced regulated pressures; the exact adjustment range for this type is not published in the material we hold, so confirm your setpoint with us on request. The A code is the automatic drain, which ejects collected condensate by itself instead of the default differential-pressure drain, suiting unattended or continuous-duty installations.
