VIVOSUN G4 Smart Filtration Kit 4" Inline Fan 195 CFM with Wi‑Fi Controller & Carbon Filter — Low-Noise, App-Controlled Ventilatio

The VIVOSUN G4 Smart Filtration Kit is an all-in-one 4" ventilation system combining a mixed-flow inline fan, Wi‑Fi controller, activated carbon filter, and 8' ducting for efficient air exchange and odor control in grow spaces.

This kit bundles components designed to work together: a 195 CFM AeroZesh G4 inline duct fan for strong, low-noise airflow; a GrowHub E42A+ smart controller with temperature, humidity, and VPD monitoring; a high-absorption RC 412 carbon filter; and reinforced 4" ducting with clamps. Together they simplify ventilation setup, let you automate runs, and help manage smells and microclimate in small tents, cabinets, or grow boxes.

How does this system improve airflow and reduce noise?

The AeroZesh G4 mixed-flow fan moves up to 195 CFM while running quietly (about 39 dBA). Its mixed-flow design maintains airflow over longer duct runs and higher static pressure, while PWM control helps you dial in the exact speed needed for stable circulation.

• 195 CFM peak airflow for efficient exchange
• Mixed-flow design for consistent output across ducting
• PWM speed control for quieter, energy-efficient operation
• Measured noise around 39 dBA under typical loads

What monitoring and automation does the GrowHub E42A+ controller provide?

The GrowHub E42A+ offers integrated temperature and humidity sensing plus a probe for localized readings and VPD awareness. It’s Wi‑Fi enabled and App-controllable so you can view conditions, schedule fan speeds, and react to environmental shifts remotely.

• Built-in temp and humidity sensors with one probe for spot measurements
• VPD monitoring to help target transpiration-friendly conditions
• Wi‑Fi and App control for remote adjustments and alerts
• Compatibility with the fan’s PWM input for automatic speed changes

How effective is the carbon filter for odor control?

The supplied filter uses RC 412 Australian virgin charcoal rated 1200+ IAV and a 38 mm deep charcoal bed to capture odorous compounds and volatiles. Its fine microporosity increases adsorption surface area, making it suitable for small to medium grow spaces when paired with the appropriate fan speed.

• Premium RC 412 Australian virgin charcoal for strong adsorption
• 1200+ IAV rating indicating high activated carbon activity
• 38 mm charcoal bed depth for improved contact and capture
• Includes rope hangers for secure in-tent suspension

What connectors and ducting are included, and how durable are they?

The kit includes 8' of 4" reinforced aluminum ducting built with a PET thermoplastic middle layer for extra strength, plus two stainless-steel clamps for tight seals. These components reduce leaks and resist crushing or kinking compared with single-layer ducting.

• φ4" 8' black ducting with a reinforced PET center layer
• Aluminum construction for flexibility without losing strength
• Two heavy-duty stainless steel clamps for secure joins
• Designed to minimize air leaks and maintain consistent flow

Who is this kit for? The VIVOSUN G4 Smart Filtration Kit is aimed at hobbyists and small-scale cultivators who want a compact, wireless-controlled ventilation solution that balances airflow, odor suppression, and quiet operation. It’s a good match for 1–4 plant tents, closet grows, compact hydro setups, and anyone who prefers remote monitoring and automated environmental control without assembling parts from multiple brands.
