Viano OS3 Car Rodent Repeller Martens Rats Mice DUO-LED Ultrasonic
Description
VIANO Rodent Repeller DUO-LED – automotive protection against martens, rats and mice
VIANO Automotive Rodent Repeller DUO-LED is a reliable device protecting the engine compartment against martens, rats and mice. Thanks to the combination of two ultrasonic emitters with an intensive LED diode, it effectively repels even the most persistent pests, preventing costly repairs resulting from chewed cables and seals.

Intelligent operation control – the electronic module automatically deactivates the device after starting the engine and activates it again after switching it off. This is a unique feature that distinguishes VIANO® from the competition. With very low current consumption of 15 mA, the repeller can operate for up to 5 months on a fully charged battery.
Key features
- Dual repelling system: two piezoelectric speakers + powerful LED diode
- Automatic frequency variation: prevents rodents from becoming accustomed
- Intelligent activation: automatic switching on/off depending on engine operation
- Simple installation: only two wires to the battery (90 cm length)
- High resistance: operates in temperatures from -30°C to +70°C
- Safe for dogs: ultrasound beyond dogs' hearing range
Installation in minutes – the device connects directly to the battery using wires terminated with ring connectors. The set includes English operating instructions with detailed installation description. The built-in fuse socket provides additional protection against short circuits.


Robust construction for harsh conditions – piezoelectric speakers made of brass are protected by special covers, which protect them against mechanical damage and contact with oil and other operating fluids. Unlike cheap products from Asia, the VIANO® device is manufactured in Poland and adapted to the variable climatic conditions of Europe.
