The AirTAC GFR60020NT AirTAC Filter Regulator 3/4in NPT 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 AirTAC GFR60020NT is a 600-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, the standard 40 um filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is high enough. No gauge is fitted, so add a gauge separately if you want a local pressure reading at the unit.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with a choice of PT, G or NPT threads, drain types and filter grades. Flow figures are published as curves rather than a single rating, 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.

| 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. |
| (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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Drops a 3/4 in compressed-air main feeding a production department from header pressure to the working pressure the downstream tools and actuators need, while stripping water and pipe-scale from the main supply.
Filters and regulates the air feeding the pneumatic cylinders on a carton-forming or case-packing conveyor, keeping set pressure stable as multiple cylinders fire in sequence.
Conditions the supply to a bank of air-operated process valves on a skid, delivering clean, regulated air so the positioners and actuators see consistent pressure through every stroke.
Size and port are the first decision: the 600 size with its 3/4 in port suits the highest flows in the range, while 200/300/400 cover smaller lines. Drain type is a real choice here: differential-pressure (this unit) drains on pressure differential, automatic drains on a timer-free float principle, and manual requires operator action. Filter grade is 40 um standard or 5 um with the W suffix; gauge and scale (MPa, psi or bar) can be ordered if needed. Thread is NPT on this code, with PT as the standard and G also orderable; a mounting bracket is included.
Flow for this family is published as curves, not a single rated figure, so send us your line size and demand 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. 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 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line size and air demand and we will confirm the flow curve and sizing from the datasheet on request.
No. The N suffix in GFR60020NT means no gauge is fitted. A gauge can be ordered separately, with a choice of embedded square or external round style and MPa, psi or bar scale, if you want a local pressure reading at the regulator.
