The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT 5 um 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size configuration carries 1 in. PT ports, a fine 5 um filter element (the W grade, against the 40 um standard), a manual drain on the bowl, and a low-pressure regulator type suited to applications where the working set-point sits below the standard range. The embedded square gauge is fitted and reads in psi, and the bowl on this size is aluminium alloy.
This is a genuine AirTAC part. The GFR line spans sizes 200 to 600 with port sizes from 1/8 in. to 1 in., a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (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. |
| 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.

At the 1 in. plant-air drop feeding a press or forming machine, this unit strips water and 5 um particles from the supply and holds a reduced, low-pressure setting for the clamping and ejection circuit, with the psi gauge giving the operator a direct reading.
On a bottling or cartoning line, the run of conveyor diverters and pusher cylinders needs clean, dry air at a steady reduced pressure; this filter regulator conditions the 1 in. branch line and its manual drain lets maintenance empty the aluminium bowl at shift checks.
Where large process or batching valves are actuated at reduced pressures, the low-pressure regulator type in this unit sets the supply to the valve positioners and actuators, with 5 um filtration protecting the pilot components from water and particulate carryover.
Step up or down through the GFR sizes (200/300/400/600) so the port and body match the air demand of the circuit; this is the 600 size with 1 in. PT ports, the largest in the line. Choose the drain to match maintenance practice: manual (as here) means an operator drains the bowl, while automatic and differential-pressure drains discharge condensate without hands-on attention. Pick 5 um (this unit) when downstream equipment needs finer filtration than the 40 um standard. The low-pressure regulator type in this code is selected when the working set-point is below the standard range; the exact range is not published, so confirm it with us. Gauge scale (this unit reads psi) and thread (PT standard, G or NPT to order) finish the selection. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing before you order.
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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow curve and sizing for this 1 in. unit before you order.
The M in the code specifies a manual drain: an operator opens the drain to empty collected condensate from the aluminium bowl. AirTAC also offers an automatic drain (code A) and a differential-pressure drain (blank) on GFR units, which discharge condensate without hands-on attention; choose those when the unit is mounted where regular manual draining is impractical.
