The AirTAC GFR600-25 AirTAC Filter Regulator PT1 Low-Pressure 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 holds downstream pressure at a set point, all in one body. This size-600 unit carries a 1 in PT port, the low-pressure regulator type, a manual drain on the aluminium alloy bowl, the 40 um standard filter element and an embedded square gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the mounting bracket is included, and no reverse/check valve is fitted.
This is a genuine AirTAC part, rated for -5 to 70 C (non-freezing). The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, and options that include a 5 um element (code W), automatic or differential-pressure draining, gauge scales in MPa, psi or bar, and G or NPT threads in place of PT. Flow figures are published as curves rather than a single rating, so ask us to confirm datasheet numbers 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. |
| (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. |
| (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 spray booth or coating line, the low-pressure regulator holds a gentle atomizing set point while the 40 um element strips water and scale that would fisheye the finish. The manual drain lets an operator bleed accumulated condensate at the start of each shift.
Pneumatic clamps on a robotic weld fixture need steady pressure below the shop main. This unit filters the supply and regulates it down for the clamp circuit, and the 1 in PT port suits a manifold feeding several fixtures from one prep point.
Air knives that dry bottles ahead of labeling run at a low regulated pressure. This filter regulator cleans the supply and holds the set point, the psi gauge gives operators a visible reference, and the manual drain clears condensate between runs.
Choose the size and port step against the air demand of your line - here that is size 600 with a 1 in PT port, the largest step in the family. Pick the drain: this unit is manual, so the bowl is bled by hand; automatic and differential-pressure draining are available on other codes. Filter grade is the 40 um standard element, with 5 um (code W) as the option. The gauge is the embedded square type reading psi; an external round gauge and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included. Flow is published as curves rather than a single rated figure, so send us your application 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 family as curves rather than a single rated figure, so we do not quote a number here. Tell us your line's air demand and working pressure and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure regulator type, intended where the set point sits well below full line pressure. Its exact adjustment range is not published in our data; standard GFR units with a manual drain adjust from 0.05 to 0.9 MPa (7 to 130 psi). Ask us to confirm the low-pressure range against your set point.
