The fan is equipped with a back valve to prevent back flow and heat losses during the fan standby. The fan exhaust spigot incorporates specially designed air rectifiers to reduce air turbulence, increase air pressure and lower noise level. Low energy demand from 8 W due to new high-efficient motor. Protection rating IP 44. Designed for continuous operation and requires no maintenance. Motor equipped with overheating protection. Manual control with a room light switch. The switch is not included into delivery set. The fan is controlled by the built-in pull cord switch V. Not applied in case of ceiling mounting.
