VEVOR Inline Duct Fan, 807 CFM 8 inch EC Motor Ventilation Fan with 3-Speed Circulation, 10-Speed PWM Controller, Timer-Controlled Operation, Cooling for Grow Tents, Indoor Gardening, Hydroponics

VEVOR 8-inch EC inline duct fan

This eight-inch inline fan addresses stale air and heat buildup in ducted grow tents or enclosed cultivation areas. The EC motor and PWM settings are useful when airflow must change during the day without swapping the entire fan.

How this version works

VEVOR identifies this as the EC 8-inch version with a PWM button controller, not the app-controlled model. The listing states a maximum free-air output of 807 CFM, three circulation modes and ten fine speed levels. It also describes a timer, so ventilation can be scheduled rather than left at one continuous setting.

Choosing it for the right job

This is a choice for an 8-inch duct run where speed adjustment matters. Do not assume that the quoted low-speed 29.2 dB or peak flow will describe the noise and airflow once filters and long ducts are fitted. Size the duct run and any filter for pressure losses; the 807 CFM rating is not necessarily the flow delivered after installation.

Setup and ongoing use

Check where a filter, duct bend and the speed controller will be installed; a tightly enclosed cabinet or blocked intake can undermine the benefit of the larger fan. Plan where to mount the housing, controller and duct connections, and keep the air path unobstructed.
