The unstoppable rise of Isomax Acoustic Fans has been one of the major success stories of recent years in the UK indoor gardening market. With a reassuringly robust design and high quality components, each of the four different sized units will comfortably help you overcome the challenges of extracting air from a modern grow room. Key features include the innovative baffle and acoustic lined chamber (much like a very large silencer) that successfully combine to minimise overall noise output whilst allowing for movement of gargantuan amounts of air.
