High flow air diffusers with 3 and 6 outputs and high induction cones

A fundamental part for the correct operation of an evaporative cooling system is air diffusion and that is why at MET MANN we have developed a range of 3 and 6 outlet long-range air diffusers as well as a range of high induction.

Evaporative cooling or ventilation systems produce a large amount of air and selecting unsuitable diffusers can cause excessive noise level, blade breakage or incorrect air diffusion.

Our air diffusers are characterized by being robust and offer a special design and construction to avoid loss of air pressure and obtain the best diffusion and range performance.
