Looking for a jet grille for your spiral pipe? Here you will find all the short and long jet diffusers for mounting on spiral pipes! Due to the aerodynamic design of jet diffusers, the air flow can be directed very precisely and the air can be supplied at high speed. This makes the grilles ideal for high spaces, such as shopping centres and industrial halls. At high air velocities, these grilles deliver a low noise level! The jet diffusers are available for different duct diameters, choose directly the diameter of your spiral tubes:
