The AirTAC GFR600-25MLC2W AirTAC Filter Regulator PT1 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 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 GFR600-25MLC2W is a size-600 filter regulator: water and particulate removal plus pressure regulation in a single body, sized for a PT1 (1 inch) port. This configuration carries the 5 um filter element (code W) for finer filtration than the 40 um standard, a manual drain for the aluminium alloy bowl fitted at the 600 size, and the low-pressure regulator type for circuits that run below standard supply pressure. A round external gauge on the psi scale is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR line spans sizes 200 to 600 with port sizes from 1/8 inch to 1 inch, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures against 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.
| 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). |
| 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.

On a carton-sealing or bag-closing line, this unit filters the plant air to 5 um and holds a reduced, low-pressure setting for the sealing and tuck cylinders, with the psi gauge giving operators a local setpoint readout.
In a press-shop clamping fixture that must not run at full header pressure, the low-pressure regulator type lets the setter bring clamp force down gently, while the 5 um element protects the fixture's control valves from water and swarf.
Feeding divertors, stoppers and pop-up rollers on a distribution conveyor, this 1-inch filter regulator conditions the main drop leg, with the manual drain emptied during scheduled line checks and the bracket fixing the unit to the frame.
Step up through the GFR sizes (200/300/400/600) until the port and body match the flow your line needs; this unit is the top of the range at PT1 (1 inch). Choose the drain to suit access: manual (as here) when an operator can bleed the bowl, automatic or differential-pressure where unattended draining matters. Pick 5 um (this unit) over the 40 um standard when downstream valves and cylinders need finer air. Gauge scale is selectable (MPa, psi or bar); this unit ships with a round psi gauge. Thread is PT as standard with G and NPT as order options, and a bracket is included.
Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet 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 number, so we do not quote a figure here. Tell us your application and we will confirm the flow and full datasheet figures for this unit on request before you order.
The M in the code sets a manual drain: an operator opens the bowl drain during maintenance rounds instead of relying on automatic or differential-pressure draining. The W sets the 5 um filter element, one grade finer than the 40 um standard, for cleaner air to downstream valves and cylinders.
