The AirTAC GR20008C1TK 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, 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 GR20008C1TK is an AirTAC GR-series air pressure regulator for compressed air: it sets and holds a stable downstream working pressure. This 200-size unit is threaded NPT1/4 (1/4 in), with a standard regulation range of 0.05-0.9 MPa (7-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). A round pressure gauge scaled in MPa is fitted so the set pressure can be read directly, and the K code means a reverse (check) valve is fitted so downstream pressure is retained if the supply is interrupted. The mounting bracket is included, and the GR body is also panel-mountable. Operating temperature is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with gauge scale and check-valve options to order. Flow is published 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 and hold a fixed clamp pressure on a fixture's air cylinders so workpieces are gripped consistently; the check valve holds the set pressure if the shop air drops.
Feed carton-sealing and case-packing cylinders at a controlled working pressure so actuation is repeatable and downstream components are not over-pressurised.
Give each air tool or bench-mounted actuator its own adjustable supply pressure, with the MPa gauge letting operators read and reset the setting quickly.
Start with the port step: this unit is 200 size with a 1/4 in NPT port; step up to GR300, GR400 or GR600 (3/8 in to 1 in) as your line size and air demand grow. Set the downstream pressure you need against the 0.05-0.9 MPa (7-130 psi) range; if your circuit runs below that, the GR low-pressure type (code L, up to 0.4 MPa) is the alternative. Choose the gauge scale - MPa, psi or bar - and round (external) or square (embedded) style. Choose thread: PT is the standard; G (BSPP) and NPT (as on this unit) are catalogue options to order. Add K for a reverse/check valve where downstream pressure must be held, and J if you do not want the bracket. Because flow is published as curves, not a single rating, 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 GR flow as performance curves rather than a single rated figure, so no rated flow number is quoted here. Tell us your line pressure, set pressure and expected air demand and we will confirm the datasheet flow figures for this 200-size, 1/4 in unit on request before you order.
C is the round (external) gauge, 1 is the MPa scale, T means the 1/4 in port is threaded NPT instead of the PT standard, and K means a reverse (check) valve is fitted. The bracket is included as standard, and the GR body can also be panel-mounted.
