VIVOSUN 4-Inch Air Filtration Kit — T4 Inline Fan 210 CFM, Carbon Filter & E12 Controller, Low Noise

The VIVOSUN T4 Air Filtration Kit is a complete 4-inch ventilation system that pairs a 210 CFM mixed-flow inline fan with a programmable speed controller, high-absorption carbon filter, and reinforced ducting for clean, quiet air movement.

This kit bundles everything needed to improve airflow and odor control in small grow tents, closets, or workshop cabinets. Built around the AeroZesh T4 4" inline fan, it emphasizes energy-efficient performance, low operating noise, and layered odor reduction using RC 412 Australian virgin charcoal. The included E12 controller gives precise speed settings and cycle modes for automated airflow management, while the aluminum-core ducting and secure clamps simplify installation and reduce leaks.

How does the VIVOSUN T4 kit manage odors and airborne contaminants?

The carbon filter uses a 38 mm thick bed of high-porosity RC 412 Australian virgin charcoal to capture volatile compounds and reduce strong smells. Its construction maximizes contact time between air and charcoal, improving adsorption without excessively restricting airflow.

• 1200+ IAV activated charcoal for enhanced adsorption capacity
• 38 mm thick charcoal bed with high microporosity
• Hang-ready design with rope hangers for optimal vertical placement
• Aluminum flange for leak-resistant connection to the fan

What performance and noise characteristics can I expect from the fan?

The AeroZesh T4 mixed-flow fan delivers up to 210 CFM while maintaining a quiet profile around 28 dBA. Mixed-flow blades propel air longer distances than typical axial fans, which helps maintain consistent ventilation across compact grow spaces.

• Max airflow: 210 CFM suitable for small tents and cabinets
• Low noise operation: approximately 28 dBA for minimal disturbance
• PWM control for more efficient speed modulation
• Mixed-flow design for higher static pressure and longer reach

How does the E12 speed controller improve airflow control and energy use?

The E12 controller offers ten discrete PWM speed settings, memory recall after power cycles, and three programmable on/off cycle modes to automate ventilation schedules. Integration with an app-enabled system allows remote monitoring and further customization if you choose to expand your setup.

• Ten selectable PWM speeds for precise airflow tuning
• Backup memory restores last speed after power interruptions
• Three ON/OFF cycle modes to reduce runtime and save energy
• App integration option for remote control and scheduling

What components come with the kit and how easy is installation?

The kit includes the AeroZesh T4 4" inline fan, E12 controller, 4" black carbon filter, φ4" 8-foot reinforced ducting, two stainless steel clamps, and rope hangers. Components are pre-matched in diameter for straightforward flange connections; the heavy-duty clamps and aluminum duct core help maintain a secure, low-leak installation.

• All parts sized for 4" ductwork to avoid adapter losses
• Durable aluminum-reinforced ducting with PET core for flexibility
• Two stainless clamps and rope hangers included for fast setup
• Compact kit designed for quick assembly in tight spaces

Who is this for: The VIVOSUN T4 Air Filtration Kit is designed for hobby growers, small-scale indoor gardeners, and anyone who needs compact, reliable ventilation with strong odor control. It’s especially appropriate for 2x2 to 3x3 grow tents, small workshop cabinets, or any enclosed area where quiet, adjustable airflow and efficient filtration matter. If you want a balanced system that’s easy to install, energy-aware, and tuned for modest spaces, this kit provides the core components in one package.
