The AirTAC GR60020LF2K AirTAC Air Pressure Regulator 3/4 in PT 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 GR60020LF2K is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream air pressure, and it does nothing else. This is the low-pressure type (code L), so it regulates up to 0.4 MPa, and it is built in the largest 600 size with a PT3/4 (3/4 in) port. It carries a maximum inlet pressure of 1.0 MPa (145 psi), operates from -20 to 70 C (the widest temperature range in the G family), and has no filter and no drain bowl, because a regulator has no bowl. The embedded square gauge is fitted with a psi scale, and the code K means a reverse (check) valve is fitted so downstream pressure is held if upstream supply drops.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, standard or low-pressure regulation, gauge or no gauge, MPa/psi/bar scales, optional reverse valve, and PT, G or NPT threads. Flow for this series is published as curves 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.

| 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. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

On a fixture or jig that uses air clamps which must not see high pressure, this low-pressure regulator holds the circuit at a safe setting, while the fitted check valve keeps the clamps from relaxing if the main supply dips.
Spray, misting and coating stations need air delivered at a steady, moderate pressure to keep the finish consistent; a 3/4 in low-pressure regulator on the supply leg to the atomizing valves gives the operator a set-and-hold point with a psi gauge to read.
Packaging and case-sealing machinery with 3/4 in air drops benefits from a dedicated regulation point per machine; this unit sets the machine's working pressure low and stable, and the included bracket mounts it at the machine's air inlet.
Start with the port and size step: this unit is 600 size on a PT3/4 port, the largest step in the range, so match it to your line size and required air demand; if your circuit is smaller, the 200/300/400 steps cover ports from 1/8 in to 1/2 in. Next, check the regulation band: this is the L (low-pressure) type, regulating up to 0.4 MPa, so it suits circuits that must never run above that ceiling; the standard GR type covers up to 0.9 MPa. The fitted square gauge reads in psi; MPa and bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the mounting bracket is included (GR is also panel-mountable). One honest note on sizing: flow for this series is published as curves, not a single rating, so send us your application details and we will confirm the figures before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR-series flow as curves rather than a single rated figure, so we do not quote one number here. Tell us your inlet pressure, set pressure and the air demand of your equipment, and we will confirm the datasheet flow figures for this 600-size, 3/4 in unit against your application before you order.
L is the low-pressure type of the GR regulator: it regulates up to 0.4 MPa instead of the 0.9 MPa ceiling of the standard type. Choose it when your downstream equipment must never be exposed to high pressure. The rest of the code reads: 600 size, PT3/4 port, square gauge with psi scale, K for a fitted reverse (check) valve, and PT thread as standard with G and NPT available as order options.
