The AirTAC GFR60020AJNWTK AirTAC Filter Regulator NPT3/4, 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 PT3/4" ports, a automatic 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 GFR60020AJNWTK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is specified with 3/4 in NPT ports, a 5 um filter element (code W) for finer filtration than the 40 um standard, and an automatic drain that expels collected condensate without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a reverse/check valve is fitted to hold the downstream setting if supply pressure drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy. No pressure gauge is fitted (code N) and no mounting bracket is included (code J).
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, and can be ordered with manual, automatic or differential-pressure drains, a 40 um or 5 um element, a square or round gauge in MPa, psi or bar scale, G or NPT threads, and a bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic 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. |
| 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.

Filter and regulate the 3/4 in branch feeding air tools, torque equipment and clamping fixtures along an assembly line, with 5 um filtration protecting tool internals and the check valve holding settings through supply dips.
Condition and regulate the air feeding pick-and-place and carton-forming cylinders on packaging conveyors, where the automatic drain keeps condensate out of valve manifolds on lines that run unattended shifts.
Supply clean, regulated air to pneumatically actuated process valves and knife gates in a water treatment plant, with the aluminium size 600 bowl and 5 um element suiting outdoor plant rooms with heavier condensate loads.
Size 600 with 3/4 in NPT ports is the largest step in the GFR range, so start there when your line volume points to a 3/4 in supply; smaller sizes 200-400 step down in port and flow capacity. The 5 um element (code W) suits downstream equipment that needs finer filtration than the 40 um standard; both grades are available across the family. The automatic drain on this unit suits unattended installations - choose manual drain where you prefer controlled, periodic blowdown, or differential-pressure drain where condensate load is light. This configuration ships without a gauge (code N); gauge variants with square or round dials in MPa, psi or bar scale can be ordered instead. Threads are PT as the AirTAC standard, with G (BSPP) and NPT as order options, and a bracket is optional (this unit has none, code J). Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing 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 GFR600 as curves rather than a single rated figure, so there is no one rated flow number we can quote. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request before you order.
In the code GFR60020AJNWTK, W selects the 5 um element (finer than the 40 um standard) and A selects the automatic drain, which expels condensate without manual attention. The N means no gauge is fitted and J means no bracket. The same size 600 body can be ordered with a 40 um element, manual or differential-pressure drain, a square or round gauge in MPa, psi or bar scale, a bracket, and G or NPT threads instead of the PT standard.
