Series VENTS Quiet-Mild Duo

• Innovative exhaust fan with stylish design.
• Ideal for intermittent or continuous ventilation of bathroom, showers, kitchens and other utility spaces.
• Two-speed ventilation up to 170 m³/h.

• Permanent low-speed operation mode ensures continuous minimum air exchange in the room.
• Ventilation shaft mounting or connection to Ø 100 and 125 mm air ducts.

• The casing and the impeller of the fan are made of high-quality durable plastic, UV resistant.
• The aerodynamic design of the impeller ensures high air flow and low noise level.
• The compact design enables wall and ceiling installation.
• A shortened spigot for mounting into a ventilation shaft or direct connection to Ø 100 mm and 125 mm air ducts.

• The fan is equipped with a specially designed backdraft damper to prevent back flow and heat losses during the fan standby.
• The fan outlet pipe incorporates specially designed air rectifiers to reduce air turbulence, noise level and increase air pressure.
• High ingress protection rating makes the fan the ideal bathroom ventilation solution. The electronic components are protected with tight covers.

• Low energy demand from 4 W due to a new two-speed high-efficient motor on ball bearings.
• Maintenance-free bearings contain enough grease for 40 000 hrs continuous operation.

• The motor on special anti-vibration dampers for vibration absorbing and silent operation.
• The motor is equipped with overheating protection.

The fan operates at Speed 1 by default. The fan switches to Speed 2 when the switch is closed or the humidity sensor is activated.

Manual:

• The fan is controlled by a room light switch. It is not included in the delivery set.
• The fan is controlled with a built-in pull cord switch "V". This option is not applicable for ceiling mounting.
• Speed control with a thyristor speed controller or a P2-1-300 speed switch, see Electrical Accessories. Several fans may be connected to the same controller. Speed controllers cannot be connected to the T and TH fan modifications.

Automatic:

• Speed control with a BU-1-60 electronic control unit, refer to Electric accessories. The control unit is supplied separately.
• By the timer T. The built-in turn-off delay timer enables fan operation at high speed within 2 to 30 minutes after the fan switching of.
• By the humidity sensor and timer TH. If the humidity level in the room exceeds the sensor threshold within 60-90 %, the fan switches automatically to a high speed and operates until the humidity level drops to the standard level. After that, the fan continues operating within the set time period and then reverts to the standard operation mode with the low speed.

• The fan is mounted directly into the ventilation shaft.
• Flexible duct connection is recommended in case of the remote ventilation shaft location. The air duct is connected to the fan exhaust spigot through a clamp.

• Fixing to wall with screws.
