The Revolution Silenced Stratos 150 AC is perfectly suited to smaller grow room environments. Developed by industry leader Systemair, they have taken their efficient and powerful classic Revolution fans and wrapped it in acoustic foam, certified for air acoustics applications, to dampen noise without restricting any air flow to your indoor cultivation environment. The fan is then sealed in steel housing to prevent odour leaks, creating the most reliable inline hydroponics fan on the market.
