Hort2O Inline Fan with Speed Control 4in - 188 CFM

Hort2O Inline Fan with Speed Control 4in -- 188 CFM

The Hort2O Inline Fan with Speed Control delivers 188 CFM of continuous airflow in a durable metal housing with a built-in speed controller for adjustable ventilation management. The integrated controller removes the need for a separate external unit, simplifying installation and reducing the number of components in your ventilation system. Designed for compatibility with Hort2O Carbon Filters, this fan pairs naturally into a matched grow room ventilation and odor control system.

Key Features & Benefits

• Built-In Speed Controller: Integrated speed control adjusts airflow without a separate external controller, reducing setup complexity.
• 188 CFM Output: Provides 188 CFM of continuous airflow at rated speed, suitable for grow tents and rooms requiring active ventilation.
• Durable Metal Housing: Robust metal construction withstands the demanding conditions of continuous grow room operation.
• 120V Operation: Plugs into standard North American outlets with the included 6.5ft power cord, no special wiring required.
• Hort2O Carbon Filter Compatible: Designed to work directly with Hort2O 4in Carbon Filters for an integrated odor control and ventilation solution.

Who Should Use This

Growers running Hort2O ventilation systems who want an inline fan and speed controller in a single unit, or anyone needing a standalone inline fan for a 4in duct ventilation application requiring 188 CFM of adjustable airflow.

Compatibility

Designed for use with Hort2O 4in Carbon Filters. The 4in duct connection is also compatible with standard 4in inline duct fittings and carbon filters from other manufacturers. 120V, 6.5ft power cord included.

Frequently Asked Questions

Does the built-in speed controller work with carbon filters?

Yes -- reducing fan speed proportionally reduces airflow through the carbon filter. Make sure the filter's minimum CFM requirement is still met at your chosen speed to maintain effective odor control.

Can I use this fan with a separate external speed controller?

The fan already includes a built-in speed controller, so adding an external controller is not recommended unless Hort2O specifies it as compatible. Stacking controllers can damage the fan motor, so use the built-in dial for all normal speed adjustments.

What size duct fittings does this 4in fan accept?

The fan accepts standard 4in duct connections. Verify duct diameter compatibility with your carbon filter and duct system before ordering.

How loud is the Hort2O inline fan at full speed?

The metal housing and balanced impeller design minimize vibration noise. Running the speed controller below full speed further reduces noise for quieter operation.
