CVS400A Inline Multi-Port Fan

Four 4" intake ports, one 6" exhaust ports, 120V, 1~

Item Number: 40119

• Designed for home spas or large bathrooms
• Centrally located exhaust fan with multiple intake ports
• 380 cfm of exhaust air
• Four 4” intake ports / One 6” exhaust port
• HVI and CSAus Certified

The CVS Series multi-port ventilator works the best for residential spas where multiple port exhaust needs to be addressed. This low profile 380 cfm fan is perfect where space is limited. CVS 400A is a popular choice for use in areas between floors in apartment buildings, high-rise office complexes or residential homes.

 

With CVS models, several exhaust points connect into one centrally located fan without the use of adapters or transitions. The motorized impeller is both statically and dynamically balanced as one integral unit, for vibration free, quiet performance.

With multiple exhaust points going into one fan, wall or roof penetrations are kept to a minimum.

 

The CVS 400A fan is simple to install. Simply select the fan mounting location, taking into account the type of application, service accessibility, and distance from exhaust point (to minimize fan operating noise). Secure the unit using either threaded rod or wires to suspend the unit. Finally, connect your flexible ductwork to inlet and outlet of the fan.
