“aira” Euro Automation offers a wide range of double-acting pneumatic actuators including rack & pinion transmission methods. We use Extruded Aluminium Hard Anodized for the body and Aluminium Pressure Die Cast for caps & rack. While the pinions are made from EN8 and the seals are available in BUNA – N and in Viton. In the making of our products, we use only high-graded quality raw materials. We maintain the international standard and designed it as per ISO 5211. Due to this design, the mounting becomes quick and easy with any valve
