Application

Multi-functional fan box for medium to bigger air flows against high resistances in ventilation systems of all kinds. The compact frame construction and mounting-friendly accessory offers through easy conversion of casing panels a variable and therefore ideal adjustment to constructional conditions.

Casing

Self-supporting frame construction made from aluminium hollow section. Double skinned, 20 mm strong side panel made from galvanised steel plate, soundproof and heat insulated through coating with non flammable mineral wool. Intake with mouth for ideal inlets as well as connectors and flexible sleeve for installation to ducts.

Extract with spigot (from rectangular to circular) for low-loss escape and flexible sleeve for prevention of impact sound transfer. Simple positioning through load hooks as standard.

Installation, mounting

Operation in any position. Simple positioning through integrated load hook. Detachable panels offer an inspection access from four sides. Noise transmission from fan to ducting and building should be avoided. The fan has to be connect via flexible sleeves (included in delivery) with the duct system.

Impeller

Free-wheeling centrifugal high performance impeller with backwards curved polymer blades (NG 250 made from steel) made from galvanised steel plate, direct powering. From NG 500 impeller is made from aluminium. Energy-efficient at low noise development. It is dynamical together with the motor to DIN ISO 1940 T.1 – Voltage steps 6.3 or 2.5.
