The AirTAC GR20006LF2 AirTAC Low-Pressure Regulator, PT1/8 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 PT1/8" 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 GR20006LF2 is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from your compressed-air supply. This unit is the size-200 body with a PT1/8 (1/8 in) port, built as the low-pressure type with an adjustment range up to 0.4 MPa, and it carries a square pressure gauge scaled in psi so operators can read and dial in the setpoint directly. As a pure regulator it contains no filter and no bowl, so it pairs cleanly with an upstream filter where air quality matters.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, gauge scale and thread options, and a panel-mountable body with bracket included on this configuration. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

Packaging machinery often uses soft clamping or hold-down cylinders that must not crush the product. This low-pressure regulator lets the line set a gentle, stable pressure below 0.4 MPa for those actuators while the main machine circuit runs at full line pressure.
Spray guns and atomizing nozzles need a steady, moderate air pressure to break up coating material consistently. Feeding the gun supply through this PT1/8 regulator with its psi gauge lets the painter lock in the setpoint and keep finish quality repeatable across shifts.
Bench-top test rigs, pneumatic sensors and small lab actuators are sensitive to supply pressure swings. This compact size-200 regulator slots into the 1/8 in instrument line and holds a low, stable pressure, with the square gauge giving a direct local readout.
Start with the port and size step: this unit is size 200 with a PT1/8 port, the smallest step in the GR range, so step up to GR300/400/600 if your line runs larger piping or higher air demand. This is the low-pressure (L) type, adjusted up to 0.4 MPa, so choose it where your process setpoint sits below standard regulator ranges; for higher setpoints use a standard GR. The square gauge here reads in psi; MPa and bar scales are available if your team works in metric. Thread is PT as standard, with G (BSPP) and NPT as orderable options to match your fittings. Bracket is included and the body is also panel-mountable. Because rated flow is published only as curves, not a single number, send us your application details and we will confirm sizing against 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 curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and downstream demand and we will confirm the sizing against the datasheet on request before you order.
L marks the low-pressure type: the adjustment range goes up to 0.4 MPa instead of the standard GR range, which suits circuits that need a lower setpoint. The F2 in the code means a square gauge scaled in psi is fitted; MPa and bar scales are available as options.
