The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, Manual Drain 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 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: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with a 1 in PT port, a manual drain for emptying the bowl, a 40 um standard filter element, an embedded square gauge scaled in psi, and a reverse/check valve that holds downstream pressure when the supply is interrupted. It is a low-pressure type regulator, and the maximum working (inlet) pressure is 1.0 MPa (145 psi). The aluminium alloy bowl on this size 600 unit is suited to applications where a polycarbonate bowl is not preferred.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um optional element (code W), gauge and scale options, and G or NPT thread variants to order. Flow for this series is published as curves rather than a single rated figure, 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.
| 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. |
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Installed at the take-off point of a plant air header, this 1 in filter regulator cleans the supply of water and scale and holds a steady low-pressure feed to the packaging machines on that ring main, with the manual drain emptied during scheduled checks.
Feeding a big cylinder-based clamping or press circuit, the unit filters incoming air to 40 um and regulates the working pressure to the level the tooling was designed for, while the check valve holds the set pressure if the upstream supply drops.
Mounted where a conveyor line's pneumatic diverters and stoppers tap off the main, this filter regulator gives that station its own filtered, regulated air supply, with the psi gauge letting line staff see and set the station pressure at a glance.
Size and port: the 600 is the largest GFR size, with a 1 in PT port - step up or down through 200/300/400/600 to match the pipe and the flow your line needs. Drain: this unit has a manual drain, which means an operator opens the drain periodically; choose automatic or differential-pressure drain codes if you want the bowl emptied without manual attention. Filter grade: 40 um is the standard element on this model; the W code gives a 5 um element if finer filtration is required. Gauge: the embedded square gauge here is scaled in psi; MPa and bar scales and an external round gauge are available. Thread: PT is the standard; G (BSPP) and NPT are order options. Bracket: this configuration has no mounting bracket (code J); bracketed versions are available.
Sizing note: flow for the GFR series is published as curves, not a single rating, so please 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 rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The M code means the bowl must be drained by hand at intervals, unlike automatic or differential-pressure drain versions which discharge condensate without operator action. This is the low-pressure (L) type regulator; the exact adjustment range for this variant is not published in the material we hold, so please confirm the range with us on request.
