The AirTAC GFR60025NWT AirTAC Filter Regulator 1 in NPT, 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 GFR60025NWT is a size-600 filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure, both in a single body. This configuration is fitted with a 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). The 1 in NPT ports suit high-flow main air lines. No pressure gauge is fitted (code N), and a mounting bracket is included. The aluminium alloy bowl is specified at this size for added robustness.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, gauge options, and PT (standard), G or NPT threads. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures on request before you order.

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 0.15 - 0.9 MPa (20 - 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Clean, regulated air feeding tool-change cylinders and clamping circuits on a machining centre, with the 5 um element guarding downstream valves from fine particulate.
A filtered, pressure-set branch feeding pneumatic cylinders and diverters on a carton or bottle conveyor line, where stable setting pressure keeps motion repeatable.
A 1 in NPT drop from the workshop ring main, conditioning and regulating air before it is distributed to individual workstations or cells.
Work top-down: pick the size and port (200/300/400/600, 1/8 in to 1 in) against the air demand of the line, then choose the drain - differential-pressure (default, self-bleeding in service), automatic, or manual for infrequently attended points. Choose 40 um for general air prep or 5 um (W) where finer protection matters, and decide whether you want a gauge fitted and on which scale. Thread is PT as standard with G and NPT as orderable options; a bracket is included by default.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we cannot quote a number here. Ask us to confirm flow against your application from the datasheet before ordering.
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 no single number can be quoted here. Tell us your line pressure, setting pressure and air demand, and we will confirm the flow from the datasheet for this size before you order.
No. The N in the code means no gauge is fitted on this configuration. The GFR family offers gauge options (embedded square gauge or external round gauge, with MPa, psi or bar scales), so if you want a gauge, ask us to quote the appropriate variant.
