The AirTAC GFR600-25 AirTAC Filter Regulator 1in PT, 5um, Manual Drain 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 the downstream pressure. This size-600 unit is fitted with a 1 in PT port, the fine 5 um filter element (code W), a manual drain on the aluminium alloy bowl, a low-pressure regulator, an embedded square gauge reading in psi, and a reverse/check valve. The manual drain means an operator opens the drain at the bottom of the bowl to discharge collected condensate, which suits installations visited on a routine maintenance round. The aluminium bowl is the material used at size 600, and this configuration ships without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, standard or low-pressure regulators, and gauge options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. |
| 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. |
| 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.

Feeds blow-off and air-knife stations on a carton or bottle packaging line, where a low-pressure regulator holds a gentle, stable setting while the 5 um element keeps moisture and fine particles off the nozzles.
Conditions and regulates the air feeding positioners and low-pressure actuated valves across a treatment train, with the manual drain emptied during the operator's daily walk-round and the psi gauge read at a glance.
Serves bench and pilot rigs that run at reduced pressure, where the fine 5 um grade protects sensitive instrumentation and the check valve holds the set circuit if the upstream supply dips.
Step up through the GFR sizes (200, 300, 400, 600) as your port and flow demand grows; this unit sits at the top of the range with a 1 in PT connection. Choose the drain to match your maintenance routine: manual (as here) for attended plants, automatic for unattended duty, or the differential-pressure default. The 5 um element (code W) is the finer choice over the 40 um standard where downstream equipment needs cleaner air. Gauge scales are available in MPa, psi or bar - this unit carries the square gauge in psi. PT is the standard thread; G (BSPP) and NPT are order options. A bracket is optional on this family, and this code omits it.
Because flow is published as curves and not as a single rated figure, and because this is the low-pressure regulator type whose exact adjustment range is not published on the sheet we hold, please confirm both with us 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 GFR flow as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your application and we will confirm the datasheet and check the sizing for you before you order.
This unit has a manual drain: an operator opens the bowl drain to discharge collected condensate, which suits rounds where someone is on site regularly. The GFR family is also available with automatic or differential-pressure drains - ask us for the alternative code if your installation is unattended.
