Inline Cooling Fan

What Does Inline Cooling Fan Mean?

In growrooms, an inline fan (as opposed to a portable stand-up or clip-on oscillating fan) can be part of both a cooling system for indoor grow lights (used with air-cooled reflectors), as well as an exhaust system that helps remove stale, moisture-laden air from an indoor growing area, reducing the chance of mold development and growth.

Inline cooling fans come in a broad range of sizes, strengths, and styles, and can have any number of features. For instance, a powder-coated finish can help the fan withstand moisture and last longer, while low-RPM fans operate more quietly, particularly if equipped with a mixed-flow impeller. Inline fans can and should be combined with filters to clean air and remove potentially harmful particulates when part of an inbound air system.

Indoor growing has become an important solution for gardeners in areas where arable land is not immediately available, those in urban areas, and many others. However, it comes with a range of challenges that must be overcome. Lighting, moisture control, cooling, and airflow are just a few of these. An inline cooling fan can help with several of those potential issues.

An inline cooling fan is essentially exactly what it sounds like – a small fan that sits within the line of existing ductwork. It serves to move air in a desired direction, and can be part of both cooling systems, as well as exhaust systems.

In a cooling system, an inline cooling fan would be used to help cool grow lights, reducing the amount of heat generated within an indoor growing area, and potentially lengthening the lifespan of grow light bulbs. In an exhaust system, an inline cooling fan would be used to help move stale air out of an indoor growing area to control the amount of moisture in the area, prevent mold and bacteria growth, and ensure healthier plants.

Inline fans are built (mounted) inside a grow rooms overhead ductwork. Some inline fans are paired with screens to keep out unwanted pathogens, and filters to remove and control unpleasant odors. Inline fans are not installed directly onto the ceiling, rather, they are found inside ducts and are common in homes and office buildings in addition to grow rooms.
