Silenced, sealed and stealthy – the Revolution Silenced Vector 250L EC is the ultimate silenced fan for your grow room environment. Systemair have taken their hugely popular classic Revolution EC fan and wrapped it in acoustic foam to dampen noise, without restricting air flow – cutting the noise in half when compared to a standard Revolution EC fan. The entire fan is then sealed in a steel housing to prevent any odour leaks from your indoor cultivation environment.

• Sealed steel housing to stop odour leaks
• Great air flow and superior performance
• EC technology for energy efficiency
• Half the noise of a standard Revolution EC fan
• Fully serviceable
• Power 165 Watts
• Maintenance free and reliable quality – made in Germany
