The AirTAC GR60020LNT AirTAC Air Pressure Regulator NPT3/4 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT3/4" ports, ordered without a gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR60020LNT is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream air pressure, and it does nothing else - no filtration and no lubrication are built in. This is the 600 size with a 3/4 in NPT port, in the low-pressure (L) type, which regulates up to 0.4 MPa. It carries no gauge (code N) and no reverse/check valve, and it comes with a mounting bracket; the GR series is also panel-mountable. Maximum inlet pressure is 1.0 MPa (145 psi), and the GR series works across -20 to 70 C, a wider temperature window than the rest of the G family.
This is a genuine AirTAC part. The GR series spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, standard and low-pressure regulation types, gauge and no-gauge variants, and PT, G and NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet flow data for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GR600 | G-series pressure regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |
| (blank) | Fixing 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. |
| 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, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with 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 rather than from a single rated figure.

On a carton-sealing or case-packing line, clamp and hold-down cylinders often run at reduced pressure to avoid crushing product. The GR60020LNT set downstream of the main supply holds that lower, stable pressure on a 3/4 in header feeding the clamp stations.
Spray booths and finishing lines need a gentle, steady atomizing and conveying air pressure rather than full line pressure. This low-pressure GR regulator on the booth's 3/4 in air drop lets the operator set and hold the reduced setting the finish demands.
Looms, stenter frames and web-cleaning air knives use low-pressure air jets where excess pressure wastes air and disturbs the web. The GR60020LNT on the jet manifold supply keeps the jet pressure at the set point across a full shift.
Size and port are the first choice: 600 is the largest GR size, with a 3/4 in port here, and the right step depends on the air demand of the line it feeds - we can check the published flow curves against your requirement before you order. This unit is the low-pressure (L) type, regulating up to 0.4 MPa; if your process needs up to 0.9 MPa, the standard GR type is the correct pick instead. Thread here is NPT; PT is the catalogue standard and G (BSPP) is also an order option. A gauge (round or square, MPa / psi / bar scale) and a reverse/check valve are available as options but are not fitted on this code, and the bracket is included.
Be aware the GR regulates only: if the air also needs water and particulate removal, pair it with a GF filter, or step to a GFR filter-regulator. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your inlet pressure, set pressure and air demand, and we will confirm the datasheet flow data for this exact model on request before you order.
L is the low-pressure regulator type: this unit regulates up to 0.4 MPa. If your application needs the full standard range up to 0.9 MPa, order the same 600 size GR without the L code. Maximum inlet pressure is 1.0 MPa (145 psi) either way, and the GR series operates from -20 to 70 C.
