Clean Airflow Without the Noise or Guesswork
Musty air, lingering odors, and rising heat can quickly make indoor spaces uncomfortable — especially in grow rooms, greenhouses, basements, and enclosed work areas. This complete 4-inch ventilation kit is designed to move stale air out fast while giving you full control over airflow and noise levels.
Powerful, quiet, and easy to install, it’s an all-in-one solution for creating a cleaner, better-ventilated environment without complicated setup.
Complete Ventilation Kit for Better Airflow & Odor Control
This system combines a high-performance inline duct fan, carbon filter, and flexible aluminum ducting to help improve air circulation, manage unwanted odors, and regulate airflow in enclosed spaces.
The included variable speed controller lets you fine-tune airflow based on your setup — whether you need maximum extraction power or quieter everyday operation.
Why This One Stands Out
- Variable speed control included — Easily adjust airflow without buying extra accessories.
- Quiet centrifugal design — Built to deliver strong airflow while reducing vibration and operating noise.
- Complete ready-to-install setup — Fan, carbon filter, and flexible ducting included.
- Strong airflow performance — 154 CFM airflow and 2700 RPM fan speed help ventilate enclosed areas efficiently.
- Long-lasting carbon filter — Reversible flange design helps extend filter lifespan up to 2 years.
- Flexible ducting with reinforced steel wire — Durable, flame-retardant, and easy to position.
Key Benefits
- Helps reduce stale, humid air in enclosed spaces
- Supports better airflow in grow tents, greenhouses, kitchens, and basements
- Adjust airflow levels depending on your environment
- Composite fan blades help minimize vibration and noise
- Permanently lubricated bearing requires zero maintenance
- Flexible aluminum ducting makes installation simple
- Compact 4-inch size fits smaller ventilation setups easily
Designed for Everyday Use
The inline fan uses a durable centrifugal design commonly used in ventilation and air movement systems because of its consistent airflow performance and long-term reliability.
The included carbon filter features a 50mm thick carbon layer and high-airflow mesh design to support effective odor management while maintaining strong ventilation performance.
A removable pre-filter is also included and can be replaced periodically to help extend the life of the main filter.

- Basements
- Kitchens
- Bathrooms
- HVAC ventilation setups
- General indoor air circulation
Built for Reliable Performance
