Greenhouse Intake Fan System
Intake Fan System

Provides fresh air for plants, helps control humidity, & boosts ventilation of roof vent systems!
These intake fan systems are great for supplying fresh air to plants in the winter when it is too cold for traditional ventilation systems to run. Just set it on a timer to run a couple times daily for a few minutes. Bringing in fresh air also helps keep humidity from getting too high in the winter. The larger 8' intake fan is best for boosting the ventilation / cooling provided by greenhouses with roof vent systems by bringing in cooler outside air near the plants and pushing hot air out of the vents. Both systems come with screens and a built-in damper to keep out cold air when they are not running. Requires a standard 110/120 volt outlet. OPTIONS: The adjustable elbow connector allows you to direct the flow of air up to 90 degrees, and the wye connector splits the air flow into 2 different directions. An extra screened cap is also included with the wye connector. A screened exhaust vent with damper is available as well to provide an air outlet for tightly sealed greenhouses.
Intake fans can be automated with a timer for fresh air delivery, dehumidistat for humidity control, or a thermostat for temperature control.
