The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR600-25 is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a 1 in PT port for high-capacity compressed-air lines. This configuration carries the W-grade 5 um filter element (finer than the 40 um standard), the low-pressure regulator type, a differential-pressure drain that bleeds condensate automatically as flow passes through, and an external round gauge scaled in psi. The aluminium alloy bowl is standard at size 600, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic, manual), 40 um or 5 um elements, gauge and thread options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rating, so ask us to confirm the figures against your application - we will send the datasheet 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 the 1 in distribution leg of a cartoning or wrapping line, cleaning the air and holding a low regulated pressure for the actuators and clamps downstream.
Supplies filtered, regulated air to the pusher and gating cylinders on a bottling or canning conveyor, where the low-pressure type setting matches the circuit's modest working pressure.
Conditions the supply to a wide-area air-knife or blow-off station on a washdown line, removing water and 5 um particles before the pressure is set for gentle drying.
Step up or down through the GFR sizes (200/300/400/600) to match the port and the flow your line needs; this unit is the 600 frame with a full 1 in PT connection. Choose the drain to suit access: differential-pressure (as fitted here) works without attention, automatic drains condensate continuously, and manual suits attended installations. Pick the element grade - 40 um standard for general protection, 5 um (this unit) for finer downstream cleanliness. Gauge style and scale (square embedded or round external; MPa, psi or bar) and thread (PT standard, G or NPT to order) are decodable choices, and a bracket is included with this unit. Note that this is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. Because flow is published as curves rather than a single rated figure, ask us to check 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs and we will confirm sizing from the datasheet on request.
The W in the code specifies the optional 5 um filter element instead of the 40 um standard, for finer protection of downstream equipment. C2 specifies the external round gauge scaled in psi; the embedded square gauge with MPa, psi or bar scales is the catalogue alternative, and the differential-pressure drain is the default for this family.
