VENTS 125 MF Duo

• 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.

Manual control:

• The fan is operated via a light switch (not included in the delivery set).

Automatic:

• 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. The fan with a timer and TH humidity sensor can also be controlled in manual mode, for example, using the light switch. When the control voltage is applied, the turn-on delay timer is activated for 45 seconds and the fan switches to the second speed. After disconnecting the control voltage, the fan runs for a time set by the turn-off delay timer (from 2 to 30 minutes), and switches to the first 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 flange through a clamp.

• Wall fixing with screws.
• Suitable for ceiling mounting.
