Vortex Powerfan V-Series, 12", 2050 CFM

Mixed-Flow Duct Fan for Higher Airflow at Lower Noise, 12in

Moving more air usually means a louder fan, which is a bad trade in a space you're also trying to keep quiet enough to work near. The Vortex Powerfan V-Series uses a mixed-flow impeller design that pushes a higher volume of air than a standard impeller of the same size, while running at a lower 1500-1700 RPM to keep noise down. It shares the VTX-Series' steel housing, hammertone powder coat finish, and extended collar, so the mounting and ducting hardware carry over between the two lines.

At 2050 CFM, this 12-inch V-Series model is sized for mid-size grow rooms that need more volume without added noise, and it ships with a 6 ft power cord and galvanized brackets for either mounting orientation.

Key Features & Benefits

• Mixed-flow impeller — moves a higher volume of air than a comparable standard-impeller design.
• Lower RPM operation — runs at 1500-1700 RPM, which keeps the fan quieter during extended use.
• Extended collar — simplifies duct hook-up and taping during installation.
• Balanced motorized impellers — permanently lubricated ball bearings keep operation vibration-free.
• Galvanized brackets on a 6 ft cord — let the fan mount horizontally or vertically wherever the duct run needs it.
• 100% speed-controllable — the factory-installed 120V cord allows external speed adjustment.

Who Should Use the V-Series

Growers who need strong airflow but are working in a space where fan noise matters — a converted closet, a shared building, a room near living space — are the target fit for the V-Series over the standard VTX-Series.

Frequently Asked Questions

What CFM does the 12-inch V-Series move?

This 12-inch V-Series model is rated to 2050 CFM. That rating, like every other Atmosphere Vortex model, is independently verified and searchable in AMCA's public certified-product database.

How is the V-Series different from the base VTX-Series?

The V-Series uses a mixed-flow impeller and runs at a lower 1500-1700 RPM for quieter operation, while the base VTX-Series uses a standard balanced impeller at a higher RPM. Both share the same steel housing, extended collar, and mounting hardware, so the choice comes down to airflow-per-decibel rather than compatibility.

Why does a lower RPM matter here?

A lower RPM generally means less motor and airflow noise for a given amount of work, which is why the V-Series pairs its higher-volume mixed-flow impeller with a 1500-1700 RPM range instead of running faster. Growers working near living or office space often prioritize this over raw CFM alone.

Can I mount it vertically or horizontally?

Yes, the included galvanized brackets support both horizontal and vertical mounting. The 3-piece bracket set comes with screws, so no separate hardware purchase is needed.

Is the fan speed adjustable?

Yes, it's 100% speed-controllable through the factory-installed 120V power cord. Pairing it with an external speed controller lets you back off airflow when full CFM isn't needed.
