Lo-Watt Pivotal Positive Input Ventilation Manrose

Specialist Range:

The Manrose Lo-Watt Pivotal Positive Input Ventilation (PIV) unit is designed to effectively prevent and treat condensation and mould, creating a cleaner and healthier indoor environment. Perfect for both refurbished and existing properties, it’s easy for installers to fit and discreet for homeowners to live with — offering a simple, energy-efficient solution to poor indoor air quality.

A loft-mounted positive input fan draws in fresh air from the loft, filters it, and gently distributes it into the home via a ceiling-mounted diffuser. This process replaces moisture-laden and stale air with clean, filtered air that has a lower humidity level — helping maintain a balanced, fresh atmosphere throughout the property.

This unit is made using recycled materials, meaning the colour of the plastic casing may vary slightly.

Health & Comfort Benefits:

• Reduces condensation and mould, helping to prevent damp-related health issues such as asthma, allergies, and respiratory irritation.
• Improves indoor air quality by continuously introducing filtered, fresh air — ideal for people with sensitive airways or dust allergies.
• Creates a balanced indoor climate, preventing musty odours and maintaining comfortable humidity levels all year round.
• Minimises airborne pollutants like dust mites, mould spores, and volatile organic compounds (VOCs), promoting overall wellbeing.
