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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 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 unit carries PT 1 in ports, a 5 um filter element (the finer of the two catalogue grades), and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough. Because this is the 600 size, the bowl is aluminium alloy. The regulator is the low-pressure type, and this configuration is fitted with an external round gauge reading in psi plus a reverse (check) valve, and includes a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, G or NPT thread variants, manual or automatic drain choices, 40 um or 5 um elements, and gauge options. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| 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. |

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.

Filter and regulate the main compressed air feed serving filling, capping and labelling machines, with the 5 um element protecting downstream valves and the differential-pressure drain keeping condensate off the shop floor.
Feed the pneumatic cylinders that index and stop product on a sorting conveyor, holding a steady regulated supply pressure so stops and pushes stay repeatable through the shift.
Serve spray and coating stations that run at reduced regulated pressure, where the low-pressure type regulator is the right fit and the round psi gauge gives operators a direct read in familiar units.
Size up by port and flow: the 600 size with 1 in PT ports sits at the top of the GFR range, so match it against the air demand of your circuit and let us confirm the flow curve before you order. Choose the drain to suit access: differential-pressure (as fitted here) needs no day-to-day attention, automatic drains continuously, and manual suits supervised points. Pick the element grade for the downstream equipment: 40 um is the standard, 5 um (this unit) for finer protection. Gauges can be the embedded square type or an external round gauge in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so send us your application details and we will confirm the correct size against the datasheet before you order.
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 family as curves, not as a single rated number, so there is no one figure we can honestly quote. Tell us your application and required flow and we will confirm the sizing against the datasheet on request before you order.
The L code marks this GFR600-25 as the low-pressure regulator variant, intended for duties where the regulated pressure sits below what the standard type targets. The catalogue does not publish an exact adjustment range for the low-pressure type, so confirm the range with us on request; the standard type's range is not applicable to this variant.
