The AirTAC GR60020F1TK AirTAC Air Pressure Regulator NPT 3/4 in is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 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 AirTAC GR60020F1TK is a pure air pressure regulator from the GR series: it reduces and holds a stable downstream pressure from your compressed-air supply, and it does nothing else - no filtration and no lubrication are built into this unit. This 600-size configuration is decodes as follows: a 3/4 in NPT thread port, a standard regulation type with an adjustment range of 0.05-0.9 MPa (7-130 psi), an embedded square pressure gauge with an MPa scale fitted as standard, and a reverse/check valve (code K) that holds downstream pressure when the upstream supply is removed. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C, wider than the rest of the G-series families.
This is a genuine AirTAC part. The GR series spans four sizes (200, 300, 400 and 600) with ports from 1/8 in to 1 in, and options include G (BSPP) or NPT threads in place of the PT standard, a low-pressure type limited to 0.4 MPa, alternative gauge scales (psi or bar), an external round gauge in place of the embedded square gauge, and panel mounting - the GR is panel-mountable and a mounting bracket is included with this unit. Flow is published by AirTAC as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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.

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.

Set a stable, reduced pressure on a 3/4 in branch line feeding a production hall section, so downstream machines see a consistent supply pressure regardless of header swings. The check valve holds the branch setting if the main header is shut off.
Mount the GR600 at the inlet of a control panel or manifold to give maintenance staff a local, gauge-readable pressure setting for the whole panel, with the included bracket fixing the unit inside the enclosure or on the frame.
Regulate the supply to air-operated clamps, stoppers and hold-downs on a conveyor line, where a repeatable setpoint keeps actuation forces consistent from shift to shift and the MPa gauge gives operators a clear reference.
Size and port are the first choice: the GR series steps through sizes 200, 300, 400 and 600, with larger sizes carrying larger ports (this unit is size 600 with a 3/4 in NPT thread), and the size step should be matched to the air demand of the circuit - we can check the published flow curves against your requirement before you order. Gauge choices are the embedded square gauge fitted here (MPa scale, with psi or bar scales available) or an optional external round gauge; the K code on this unit adds a reverse/check valve, which you would omit if you do not need downstream pressure retention. Thread is PT as the AirTAC standard, with G (BSPP) and NPT as catalogue options - this unit carries the NPT option. A low-pressure type (L) limited to 0.4 MPa exists if your setpoint sits below the standard range. Because AirTAC publishes flow only as curves and not as a single rated number, ask us to confirm sizing against your application before ordering.
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 regulator flow as curves in the catalogue rather than as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line size and air demand and we will confirm the flow-curve figures from the datasheet on request before you order.
The K code means a reverse/check valve is fitted: it holds the downstream pressure you have set if the upstream supply is removed, which is useful on circuits that must stay pressurised. The F1 code means the embedded square gauge is fitted with an MPa scale; psi and bar scales are available as catalogue options if you prefer.
