Immaculate Series laminar flow and distribution system suitable for general operating theatres and non-critical surgery. Constructed with an anodized aluminum profile for the insertion of terminal absolute filter housings, the diffusers can be aluminum, AISI 304 stainless steel or with fabric equalizer for LV model, ideal for low speeds. Filtration H13/ H14 HEPA filters. In Laminar flow unites for operation theatre applications, face velocity is taken between 0,2-0,3 m/s. Larger velocities from 0,3 m/s cause draught effect on people under the unite, on the other hand velocities smaller than 0,2 m/s cause deformations in laminar flow.
