ALIZÉ HYGRO, TEMPO and VISION humidity-sensitive or timed extract vents fall within the scope of Technical Opinion for humidity-controlled ventilation systems ALIZÉ 2018. They adjust extraction air flow rates in wet rooms (kitchens, bathrooms, toilets) according to the relative humidity and feature boost timers for additional extraction.
Designed for external, roof-mounted installation at the ends of ventilation ducts in residential, commercial and industrial buildings with low levels of particulate air pollution. The fan can work with the CSR-B controller, which will ensure stable ventilation operation under all conditions and exactly according to the design guidelines.
thyristor speed controller BS 1.5
Used in ventilation systems to switch on/off and regulate the speed of single-phase electric motors of voltage-controlled fans.
The BROOKVENT airstream 1.1 E / EH is an efficient and quiet continuous mechanical extract ventilation (MEV) unit with duct connections to each wet room.
