The AirTAC GR200-08NT AirTAC Air Pressure Regulator NPT1/4 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 PT1/4" 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 GR200-08NT is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from a compressed-air supply. This 200-size unit carries a 1/4 in NPT port, is the standard (non low-pressure) type, and adjusts across 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). It is rated for -20 to 70 C, wider than the rest of the G family, and this code (N) specifies no gauge fitted, so add a gauge separately if you need a visual setpoint. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, and options include a fitted gauge (round or square, MPa/psi/bar scales), a low-pressure type limited to 0.4 MPa, a reverse/check valve (K), and G (BSPP) or NPT threads in place of the PT standard. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers for 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.

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 and hold a stable clamping pressure to a cylinder circuit on a mechanical or pneumatic press, so clamp force stays consistent from cycle to cycle.
Regulate the supply pressure feeding sealing bars, diverters and pusher cylinders on a packaging line, keeping actuator speeds repeatable as plant pressure drifts.
Feed a controlled pressure to gripper and suction-circuit valves on a robotic pick-and-place cell, protecting delicate parts from over-pressure handling.
Start with the port and flow path: 200 size takes a 1/4 in port, and larger sizes (300/400/600) step up in port and flow capacity - size the unit against the air demand of the circuit rather than the pipe alone. Decide the adjustment window: the standard GR covers 0.05-0.9 MPa, while the L (low-pressure) type tops out at 0.4 MPa for sensitive circuits. Choose the thread to match your plumbing: PT is the catalogue standard, with G (BSPP) and NPT (as on this -T unit) available as order options. Add a gauge if operators need to read or verify the setpoint, selecting round or square body and MPa, psi or bar scale; this code omits the gauge. A reverse/check valve (K) can be fitted where downstream pressure must be held if supply is lost. Flow is published as curves, not a single rated figure, so 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 GR-series flow as performance curves rather than a single rated figure, so we do not quote a Cv or l/min number. Send us your application details and we will confirm the datasheet curve and sizing for this 1/4 in unit on request.
The N in the code means no gauge is fitted; GR regulators can be ordered with an embedded square gauge or an external round gauge in MPa, psi or bar scales. The -T suffix gives an NPT 1/4 in thread; PT is the catalogue standard and G (BSPP) is also available as an order option.
