APPLICATIONS

• They are used in supply and exhaust ventilation systems of various commercial and industrial premises with increased noise level requirements (libraries, conference rooms, educational institutions, kindergartens, etc.).

DESIGN

• The casing and impeller are made of high quality and durable plastic.
• The internal perforation of the casing allows sound waves to pass through, directing them at a certain angle to a layer of sound-absorbing material.
• The casing is internally heat- and sound-insulated with a 50 mm mineral wool layer.
• Single-phase energy efficient three-speed motors with low energy demand are used.
• The ball bearings provide a long service life (about 40 000 hours of continuous operation).
• The motor protection class is IPX4.
