Ventilation systems for optimum greenhouse growing environment

The ventilation system within any greenhouse plays a pivotal role in plant health and crop production. Not only are ventilation systems vital to maintaining environmental conditions but they also directly influence a plant's ability to perform photosynthesis, uptake essential elements and complete pollination. Maintain plant health with the proper Schaefer circulation and exhaust systems offered by Carpa Supply.

We offer a complete line of controls, automated inlets and outlets, circulation fans, and evaporative coolers that circulate, exhaust, and draw in air. These systems are built to handle greenhouse moisture exposure and regular cleanings, while at the same time, providing superior performance and increasing durability. The pictures above show some of our top selling greenhouse ventilation systems.
