The AirTAC GFR600-25 AirTAC Filter Regulator, 1 in NPT 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 size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is a 1 in NPT port unit with the standard 40 um filter element, manual drain, a fitted round gauge reading in psi, a reverse (check) valve, and no mounting bracket. With manual drainage, the bowl is emptied by hand as part of routine maintenance, and the aluminium alloy bowl suits this largest frame size.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT to order), drain types, 40 um or 5 um filtration, gauge styles and scales, and bracket options. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Feeding a machining cell's air drop, the GFR600-25 strips water and swarf-laden condensate from the main line and holds a steady regulated pressure to the machine's valves and cylinders, with the check valve holding settings against supply dips.
On a packaging or case-sealing line, this unit conditions the air feeding grippers and pusher cylinders, protecting them from moisture and keeping actuation pressure consistent across the shift.
Ahead of spray equipment in a finish line, the 40 um element removes water and particulate while the regulator lets the operator set and hold the supply pressure the spray station was set up for.
Start with the port: this unit is 1 in NPT, the largest size-600 step, so match it to a line where peak demand sits near the top of the range - if your consumption is modest, a 300 or 400 size may be the more economical choice. Choose the drain to suit access: manual (as here) suits attended installations, automatic suits unattended drops, and differential-pressure drain is the catalogue default. The 40 um element is the standard grade; specify 5 um (code W) only where finer filtration is genuinely needed. The round psi gauge is fitted here; an embedded square gauge with MPa, psi or bar scales is also available. A reverse (check) valve is fitted, and no bracket is included - order one if you want panel or wall fixing. Flow is published as curves, not a single rating, so 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 number here. Tell us your line pressure and air consumption and we will confirm the flow and sizing from the datasheet on request.
Manual drain means the aluminium bowl is drained by hand during routine checks - a good fit where the unit is accessible and inspected regularly; automatic or differential-pressure drain suits unattended installations. The fitted reverse (check) valve helps hold downstream pressure if the upstream supply drops.
