The AirTAC GFR60025ALJF2K 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 GFR60025ALJF2K is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 1 inch PT-threaded port version with an automatic drain, so condensed water is expelled from the aluminium alloy bowl without manual attention. It is the low-pressure regulator type, fitted with an embedded square gauge scaled in psi, and a reverse (check) valve is included. No mounting bracket is supplied with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 inch to 1 inch, a choice of automatic, manual or differential-pressure drains, 40 um or 5 um filtration, and gauge or no-gauge variants. Flow is published as curves rather than a single rating, so ask us to confirm the flow and datasheet figures for your application before ordering.

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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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.

Feeding filtered, regulated air to the cylinder and valve manifold circuits of a case-packer or palletiser line built on 1 inch air mains, with the automatic drain handling condensate between shifts.
Supplying regulated air to large-bore actuated ball or butterfly valves on process pipework where the actuator is specified for a reduced supply pressure rather than full line pressure.
Regulating the air to blow-off nozzles and hold-down clamps on a bottling or canning conveyor, with the 40 um element stopping pipe scale and water from reaching the nozzles.
Size 600 with a PT1 (1 in) port is the largest step in the GFR range, chosen when the line and the connected equipment are built around 1 inch piping; smaller sizes (200/300/400) step down in port and flow capacity. The automatic drain on this unit suits installations that are not checked daily; a manual drain needs operator attention, while the differential-pressure default drains only when the pressure differential calls for it. Filtration here is the 40 um standard element - choose the 5 um (W) variant where downstream equipment needs finer air. The embedded 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. Flow 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A in the code sets the automatic drain: condensate collected in the aluminium alloy bowl is expelled without anyone opening it, which suits unattended or hard-to-reach installations. The L in the code marks the low-pressure regulator type, intended where the regulated output sits below the standard type's range; the exact adjustment range for the low-pressure type is not published in our sheet, so we confirm it on request.
