The AirTAC GFR60020JNTK AirTAC Filter Regulator NPT3/4 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 PT3/4" 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 GFR60020JNTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your set point. This 600-size unit is tapped NPT3/4 (3/4 in) and carries the standard 40 um filter element with a differential-pressure drain that bleeds condensate as air flows through. No pressure gauge is fitted (code N) and no mounting bracket is included (code J), while a reverse/check valve (code K) is built in to hold the downstream setting if the upstream supply drops. Because this is the 600 size, the bowl 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 ports from 1/8 to 1 inch, and options across the family include a 5 um element (code W), automatic or manual drains, embedded square or external round gauges, G (BSPP) or NPT threads in place of the PT standard, and bracket variants. 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.

| 20 | Port size PT3/4". 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)). |
| (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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

At the cell drop feeding a CNC machine's pneumatic clamps, tool-changer and chip-ejection cylinders, this filter regulator cleans the shop air and holds a steady set point so clamping force does not wander between cycles.
On a press line where air cylinders position and clamp stampings, this 600-size unit conditions the main branch supply and regulates it to the pressure the tooling was set up for, with the check valve holding the setting through supply dips.
On a packaging conveyor running diverters, pushers and stopper cylinders, this unit strips water and scale from the header air and regulates it to the pressure the divert mechanism needs, protecting the cylinders from dirt and moisture.
Sizing starts with the port step: this is the 600 size with a 3/4 in NPT port, so match it to your line size and the air your actuators actually draw - because flow is published as curves, not a single rating, ask us to confirm sizing against the application before ordering. Drain type is a real choice: this unit has the differential-pressure drain (default), while automatic (code A) and manual (code M) versions exist. Filter grade is the 40 um standard here; specify 5 um (code W) where finer particle protection matters. Gauge options exist on the family, but this code (N) comes with none - add one if you want a local set-point reference. Thread is NPT on this unit; PT is the catalogue standard and G (BSPP) is an order option. No bracket is included (code J), so plan your own mounting.
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.
Flow for the GFR600 is published as curves, not as a single rated figure, so we do not quote a number on the page. Send us your line size and air demand and we will confirm the datasheet curves and check the sizing for your application on request.
No. The code ends in N, so no gauge is fitted. The GFR family can be ordered with an embedded square gauge or an external round gauge, with MPa, psi or bar scales - tell us which scale you want and we will quote the matching variant.
