The MF150S from Manrose is perfect for growers who need more airflow than a compact fan can offer but don’t want to step up to an industrial sized vent fan. Designed for quiet, continuous use, this durable fan helps stabilize environmental conditions — whether you’re dealing with hot lighting setups or dense plant canopies — and is built with a ball-bearing motor that ensures long-term use with minimal maintenance or noise. It also integrates seamlessly with carbon filters and ducting, making set up or upgrading an existing system easy. With a 150 mm duct diameter and an airflow rate of 350 m³/h, it’s perfect for medium-sized grow rooms or tents where effective heat and humidity control is crucial. If you have a smaller setup, the MF125S is a more compact option from Manrose. For growers going big, the powerful MF200S gets the job done.
