VIVOSUN D4 4 Inch Inline Duct Fan
The VIVOSUN D4 4 Inch inline duct fan delivers robust air movement with a specified speed of 2500 RPM, producing 195 CFM. It is designed for grow tents, heat transfer, and humidity regulation, helping maintain a stable grow environment. The unit emphasizes quiet operation, using a flow deflector to minimize turbulence and reduce noise output to about 30 dB. Safety features include an ETL-listed motor with an automatic reset and a flame-retardant junction box to enhance fire safety in enclosed spaces. This model suits compact to mid-size grow rooms that need dependable exhaust and airflow control.
AC Infinity CLOUDLINE PRO S6
The CLOUDLINE PRO S6 is a 6-inch inline duct fan designed for grow tents and hydroponic setups, featuring a wired 10-speed controller and compatibility with UIS intelligent controllers. The PWM-controlled EC motor provides quiet, energy-efficient performance with low heat and noise. Its design supports versatile ventilation for transferring heat or cooling rooms, filtering odors, and maintaining air quality in larger grow spaces. This model is ideal for growers seeking precise control and scalable airflow management in medium to larger installations.
VIVOSUN 4” Inline Booster Duct Fan
The VIVOSUN 4” Inline Booster offers up to 130 CFM of airflow with an upgraded EC motor for efficient performance and a long service life. It emphasizes low noise operation, delivering around 26dB(A) to minimize disruption while moving air through grow tents, basements, bathrooms, or kitchens. The booster design helps improve ventilation in tight spaces and supports reliable exhaust without a heavy power draw, making it suitable for supplemental or continuous ventilation in medium-scale setups.
Hon&Guan 4 Inch Inline Booster
The Hon&Guan booster is rated at 130 CFM with a 6W consumption, featuring a fast-growing DC motor and low-noise operation for efficient air movement. It is designed for quick installation and compatibility with various ventilation needs, including grow rooms, bathrooms, kitchens, and attics. The unit’s construction emphasizes ease of maintenance, with plastic body and blade design that facilitates straightforward cleaning and service, making it a practical option for space-constrained areas requiring reliable exhaust.
AC Infinity CLOUDLINE A6
The CLOUDLINE A6 combines compact form with quiet, efficient ventilation. It is designed to exhaust odors, transfer heating or cooling to adjacent rooms, and help preserve climate conditions in grow tents and hydroponic setups. Like other CLOUDLINE models, it supports a wired controller and is compatible with existing CLOUDLINE smart controllers for integrated climate management. This option is suitable for growers seeking a balance between space-saving design and dependable airflow control in smaller to mid-sized installations.
Buying Guide: Key Considerations For Selecting Grow Room Inline Fans
- Airflow capacity (CFM): Match the fan’s CFM to your grow space size and duct length. Underestimating airflow can lead to heat buildup and high humidity, while overdoing it may waste energy and create unwanted wind stress for plants.
- Noise level: If the grow area is near living spaces, prioritize models with low decibel ratings and noise-dampening features like flow deflectors or insulated housings.
- Energy efficiency: EC motors and variable-speed controllers reduce energy use and heat generation. Consider models with PWM control for precise tuning of airflow.
- Control options: Wired controllers or compatibility with smart controllers allow precise scheduling, auto-regulation, and integration with other climate-control devices.
- Safety and durability: Look for ETL-listed components, flame-retardant housings, thermal protection, and robust build quality for long-term use in grow environments.
- Installation versatility: Some fans are better for tight spaces, longer duct runs, or multi-room setups. Check size, mounting options, and compatibility with your ducting.
- Maintenance: Easy-to-clean blades and accessible motors reduce downtime. Consider fans with service-friendly designs for ongoing reliability.
- Price-to-performance balance: Compare CFM per watt, noise, and warranty length to determine which model offers the best value for your space.
