The Company is continually updating its products to comply with changing energy saving technologies, so the introduction of the VSI Range of extract units is based on changes in Fan technology, with the introduction of EC backward curved direct driven plug fans, with 0<10V speed control. Multi fan wall arrangements have been adopted to give higher performance with lower energy consumption.
The VSI cased extract range has been developed to meet the specific fan power requirements of Building Regulations, and additionally to meet Building Bulletin 93 noise requirement for schools and places of learning.
Extensive acoustic testing of casework construction has been carried out at both the companies testing facilities, and Salford University Acoustic Testing Laboratory. Acoustic tests were carried out on eleven double skin composite panel/frame systems, eight different triple and quadruple skin composite panel/frame systems, to BS. EN ISO 10140-2 (2010) which have all been certified as UKAS accredited.
