The new products are made on the basis of well-known Primo series of inline mixed flow fans and are designed for use with round air ducts with diameter 200 and 250 mm.
Iso-Primo series fans are an optimal solution for use in exhaust, supply and supply and exhaust ventilation systems for various premises having high requirements in terms of noise levels. These products have sound-insulated casings made of galvanized steel and 30 mm thick acoustic foam, and demonstrate high performance up to 1.110 m³/h (Iso-Primo 200) and 1.670 m³/h (Iso-Primo 250).
Polymer conical impeller with specially profiled blades ensure increased air flow circular speed, which in turn results in increased air flow capacity and pressure if compared with characteristics of standard axial fans. Specially designed diffuser, impeller and airflow straightener at the fan outlet ensure smooth air flow distribution and achieve high performance with low noise level.
The fans can be equipped with three-speed single phase AC motors with low energy consumption, as well as with highly efficient EC motors.
