The AirTAC GFR60025LJNWTK AirTAC 1 in NPT Filter Regulator 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 GFR60025LJNWTK is an AirTAC GFR600 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, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain, and the low-pressure regulator type. A reverse/check valve is fitted, and the unit ships without a gauge or mounting bracket. The bowl on this size is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
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, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge and bracket options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure 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. |
| 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.

On a bottling hall's actuated valve manifold, this unit filters water and particles from the plant air supply and holds a low regulated pressure for the valve positioners, with the check valve holding the set point if supply dips.
Feeding the gate and diverter cylinders on a packaging conveyor run, the 5 um element protects the cylinder seals from particulate while the low-pressure regulator keeps actuation gentle on product-handling tooling.
On a CNC machining cell's pneumatic clamping circuit, this unit delivers filtered air at a controlled low pressure for delicate workholding, and the fitted check valve prevents the clamp pressure from backing out through the supply line.
Size 600 with a 1 in port is the largest step in the GFR range, so start there when the line demand is high, then verify against the flow curves before ordering. This unit carries the 5 um element (code W); the standard grade is 40 um, so choose 5 um where downstream equipment needs finer filtration. The drain is the differential-pressure type, the catalogue default; automatic (A) and manual (M) drains are available in the family if your installation suits them better. The low-pressure regulator type (code L) is selected for circuits that run below standard regulator ranges - the exact adjustment range for this variant is not published, so confirm it with us. A reverse/check valve is fitted (code K). No gauge is included (code N); gauges in square or round style with MPa, psi or bar scales can be ordered separately. The thread here is NPT; PT is the catalogue standard and G (BSPP) is also available. No mounting bracket is included (code J). 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number. Send us your line pressure and required downstream flow and we will confirm the sizing from the datasheet curves on request before you order.
The code N in GFR60025LJNWTK means no gauge is fitted; a square or round gauge with MPa, psi or bar scale can be ordered separately if you want a local pressure reading. The L in the code marks the low-pressure regulator type, selected for circuits running below standard regulator ranges - the exact adjustment range for this variant is not published, so confirm it with us.
