The M5 has been designed to effectively remove odors and keep airflow high for industrial spaces or greenhouse environments. The M5 is powered by the 20 in Max-Fan? and reliably delivers 3509 CFM of clean air on only 4.8 Amps, 240 V. The M5 uses 20 pieces of the Can-Lite? 9000 filters. The 20 pieces of Can-Lite? 9000 easily connect to the M5 unit with twist style Bayonet mounts. The M5 comes fortified with a locking, insulated (sound proofed) maintenance door that opens the way to an extremely clean and easy to work with enclosure. Very compact in design, the M5 can be stacked or mounted. Can-Lite? filters are not included with this fan and must be purchased separately.
