The AirTAC GR60020LF1T 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, and ships with a pressure 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 GR60020LF1T is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream air pressure from your compressed-air supply. This is the size 600 unit, the largest in the GR range, with a 3/4 in NPT port. The L in the code marks the low-pressure type, whose setting range goes up to 0.4 MPa, and the F1 marks the embedded square pressure gauge with an MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G series. As a pure regulator it contains no filter, no drain bowl and no lubricator.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, PT, G and NPT threads, standard and low-pressure types, and gauge options. Flow for this model is published as a curve rather than a single rated figure, so ask us and we will confirm the datasheet figures against your application.

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.

| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |

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.

Sets a gentle, stable supply pressure to spray guns and air-assisted applicators on a finishing line, where the process calls for low regulated pressure rather than full line pressure.
Feeds the low-pressure clamp, hold-down and film-tension cylinders on cartoning and wrapping machines, keeping actuator forces consistent across the shift.
Regulates the pressure on blow-off nozzles, air knives and light pneumatic conveying headers in a plant, so the downstream circuit runs at the low pressure the job needs.
Start with size and port: the 600 body with its 3/4 in NPT port suits lines where larger supply piping is already in place, while 200/300/400 units cover smaller ports. Choose the standard type for settings up to 0.9 MPa or this low-pressure L type when the process must stay at or below 0.4 MPa. The embedded square MPa gauge is standard here; external round gauges with MPa, psi or bar scales are catalogue options. Thread is NPT on this code (T); PT is the catalogue standard and G is also orderable. A reverse/check valve (K) and a no-gauge build (N) are further options, and the GR can be bracket-mounted or panel-mounted. Because flow is published only as curves, not a single rating, send us your flow and pressure requirements and we will confirm sizing from the datasheet before you order.
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 regulator flow as a curve rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your line pressure, set pressure and approximate air demand, and we will confirm the sizing from the datasheet before you order.
L marks the low-pressure type: its setting range goes up to 0.4 MPa, whereas the standard GR adjusts up to 0.9 MPa. Both share the same 1.0 MPa maximum inlet pressure, the same -20 to 70 C temperature range and the same mounting options, so choose L only when your process pressure stays at or below 0.4 MPa.
