residentialbathroomfor kitchens

Two-speed axial low-noise and low energy fans for exhaust ventilation with air flow up to 300 m³/h. Continuous or periodic exhaust ventilation of bathroom, showers, kitchens, and other residential premises. Ventilation of premises with high requirements to noise level. Permanent low-speed operation mode ensures continuous air exchange in the room. Ventilation shaft mounting or connection to Ø 100, 125 and 150 mm air ducts. The casing and the impeller are made of highquality durable plastic, UV resistant. The aerodynamic design of the impeller ensures high air flow and low noise level. The fan is equipped with a specially designed backdraft damper to prevent back flow and heat losses during the fan standby. The fan outlet spigot incorporates specially designed air rectifiers to reduce air turbulence, noise level and increase air pressure. Low energy demand from 5 W due to a new twospeed high-efficient motor. Ingress protection rating IP44. Designed for continuous operation and requires no maintenance. Equipped with overheating protection. The fan is operated via a light switch (not included in the delivery set). By the T1 timer. When the external switch is turned on, the fan switches to a higher speed with a delay of 0 to 2 minutes. When the external switch is turned off, the fan will return to a low speed with a delay of 2 to 30 minutes. By the humidity sensor and the TH timer. If the humidity level in the room exceeds the sensor threshold (60-90 %), the fan will automatically switch to a higher speed and will continue running until humidity returns to normal levels. Then the fan runs for 5 minutes at a high speed and switches to a low speed.
