The AirTAC GFR60025JNWTK AirTAC Filter Regulator NPT 1 in 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 GFR60025JNWTK is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is fitted with a 1 in NPT port, the 5 um filter element (code W, finer than the 40 um standard), a differential-pressure drain that bleeds condensate automatically as flow passes through, and a built-in reverse/check valve that holds downstream pressure when the supply is lost. No gauge is fitted (code N) and no mounting bracket is included (code J). The size 600 bowl is aluminium alloy, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options for automatic, manual or differential-pressure drains, 40 um or 5 um filtration, gauges with MPa, psi or bar scales, and G (BSPP), NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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. 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. |
| J | Supplied without bracket. |
| 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.

Installed at a large distribution take-off on a factory compressed-air ring main, cleaning water and particles from the supply and holding a set downstream pressure for the whole workshop section.
Feeding filtered, regulated air to the pneumatic cylinders that clamp, push and divert packs on a bottling or cartoning conveyor, with the check valve holding position if the supply drops.
Mounted on the air drop serving a maintenance bay where impact tools, air chisels and test rigs draw from a single point, keeping scale and condensate out of the tools at a set working pressure.
Choose the size and port step against the air demand of the line: size 600 with a 1 in port is the largest step in the GFR range, so step down to 200/300/400 if your flow requirement is smaller. This unit already carries the 5 um element (W); the standard grade is 40 um, so pick the grade by how clean the downstream equipment needs the air. Drain type is a real choice: differential-pressure (as fitted here), fully automatic, or manual. If you want a visual setpoint, gauges are optional with square (embedded) or round (external) styles and MPa, psi or bar scales. Thread options are PT (standard), G (BSPP) and NPT; this unit uses NPT. Brackets are optional on GFR units, and this one is ordered without one. 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, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow and datasheet figures on request before you order.
The W in the code GFR60025JNWTK selects the optional 5 um filter grade instead of the 40 um standard, for finer particle removal. The K selects a built-in reverse/check valve, which holds downstream pressure if the upstream supply is interrupted. Both are standard catalogue options on GFR filter regulators.
