• Speed-controllable
• Integral thermal contacts
• Low sound level
• Maintenance-free and reliable
• Vertical or horizontal exhaust
The DVS/DHS models have impellers with backward-curved blades and external rotor motors. All three phasemotors are D/Y connected allowing two-speed operation ifrequired. The motors are suspended on effective vibrationdampers. The casing is made from aluminum and the baseframe is powder-coated galvanised steel. Suitable forcoastal applications.
The impellers are manufactured from aluminium.
To protect the motors from overheating the DVS/DHS havethermal contacts with external leads for connection to amotor protection device.
DVSI with 50 mm mineral wool insulation for low noiselevel.
