Breeza Industrial is expanding its line of variable-speed, electronically commutated (ECM) fans. At MJBizCon 2025 in Las Vegas, David Donohoe, sales engineer at Breeza Industrial, said his fans are designed to eliminate microclimates and balance temperature and humidity. The company also provides airflow engineering services.
"Airflow is one of the least considered factors, and airflow is everything," Donohoe said. "If you don't have a balanced climate, then you can't control everything else. Your irrigation rates are different, your heat loads are different, everything becomes a challenge, and you actually have a series of uncontrolled areas when everything isn't balanced."
Breeza will collect all pertinent details from a grow, such as air-handling equipment, airflow obstructions, and the growing canopy, and develop an airflow plan that's adjustable based on the stages of crop development. Donohoe said he provides airflow layouts not just for Breeza fans, but competitive products as well.
While ECM fans are new to the cannabis industry, they have been around a long time, typically in appliances. ECMs provide the ability to adjust airflow based on crop development and are plug-and-play with all environmental control systems on the market. So, using cloud-based control, operators can monitor their grows remotely.
Donohoe has provided airflow plans for small home grows, large commercial facilities, and everything in between. He most often runs into challenges when he is called in to assess a retrofit facility, where operators sometimes fail to leave enough space for airflow to move, especially in multitier grows when they didn't plan for large enough spacing between lights and a max canopy. Though it is challenging to move air at these facilities, Breeza has solutions.
"In reality, each grow room is unique; each situation is unique; and everything in a room has to be taken into consideration," Donohoe said. "Otherwise, you're not going to really solve the problem."
