This compact inline exhaust fan combines a powerful AC motor with a variable speed controller so you can match airflow to changing needs. Designed for continuous operation, it balances high performance and energy efficiency while keeping sound levels low. The unit ships with mounting accessories to speed installation whether you suspend the fan or attach it to a wall or duct run.

How much airflow and noise can I expect from this inline duct fan?

The fan is rated for 400 cubic feet per minute (CFM), enough to move air through medium-length duct runs and ventilate tents, small rooms, or equipment cabinets. The AC motor is tuned for quiet operation, measured around 34 dB at typical speeds, making it suitable for home or light commercial setups.

• Maximum 400 CFM airflow for efficient air exchange
• Low operating noise ~34 dB at normal settings
• AC motor designed for continuous duty and energy savings

Can I adjust airflow to match different environments?

Yes — the included variable speed controller lets you dial the fan speed to fit different ventilation demands. Turning the knob adjusts airflow smoothly so you can prioritize airflow, quieter operation, or a balance of both depending on space and equipment.

• Manual speed control with easy-turn knob for fine adjustments
• Quickly reduce speed for quieter, low-power operation
• Increase speed for high-heat or high-humidity situations

What mounting options and accessories come with the fan?

The package includes the basic hardware needed to get the fan running right away. Choose between suspending the unit with included hang straps or mounting it to a wall or flat surface using the supplied anti-vibration pads and mounting straps for a secure, low-noise install.

• Hang-up slings for suspended installations
• Non-vibration rubber mats to reduce noise and wear
• Straps and basic fittings to fast-track setup

Is this fan suited for grow tents, hydroponics, and other indoor uses?

Absolutely — the fan is built for environments where heat, humidity, and stale air must be managed. It works well in grow tents and hydroponic rooms as an exhaust or booster fan, and also supports electronics cabinets, kitchens, basements, and other spaces needing reliable air exchange.

• Effective at removing heat and humidity from grow spaces
• Compatible with standard 6-inch ducting for flexible layouts
• Durable AC motor reduces energy draw and extends service life
