The AirTAC GFR60025ALF2K AirTAC Filter Regulator 1 in PT 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 GFR60025ALF2K is an AirTAC GFR-series filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit is built around a PT 1 in port, with an automatic drain that discharges collected condensate from the aluminium alloy bowl without daily attention. The 40 um standard element handles general-purpose filtration, the L code makes it a low-pressure regulator type, and the fitted embedded square gauge reads in psi so operators can see the set pressure at a glance. A reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

| A | Drain: Automatic 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

On a warehouse palletizing line, this unit sits at the 1 in main drop ahead of the directional valves and clamp cylinders, knocking water and pipe scale out of the supply and holding a steady low-pressure setting for the clamp and push circuits.
For a bottling hall's conveyor and gating actuators, the filter section keeps condensate and debris out of the valve manifold while the low-pressure regulator holds a gentle setting suited to light-duty air cylinders, and the automatic drain copes with humid compressor air.
On a pilot-scale process skid with instrument air take-offs, the 40 um element protects pressure switches and transmitters, the psi-scaled square gauge gives a readable local setpoint, and the fitted reverse/check valve is in line for circuits that need backflow protection.
Choose the size and port against the air demand of the circuit: this 600 unit carries a 1 in PT port, and stepping up or down between sizes 200, 300, 400 and 600 changes both the connection and the flow capacity - we can confirm the curve figures per size on request. Pick the drain to match your maintenance routine: automatic (this code, A) empties the bowl on its own, manual (M) needs a routine bleed, and the blank default is differential-pressure. The 40 um element is standard; specify W for the 5 um grade where finer particulate removal matters. The square gauge here reads psi; MPa and bar scales, and an external round gauge, are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and the mounting bracket is included. Because flow is published as curves, not a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR range as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and required flow and we will confirm the figures from the datasheet on request before you order.
A is the automatic drain: the bowl discharges collected condensate on its own instead of waiting for a manual bleed. The catalogue also offers manual drain (code M) and the differential-pressure default (no code), so you can order the style that matches your maintenance routine.
