Horticulture/Greenhouse Inlets & Curtain System Inlets are an essential part of your complete ventilation system. They bring fresh air into your greenhouse where it is properly mixed and then circulated and exhausted. A well designed and well located inlet system is more important for good ventilation than the fans themselves. Our greenhouse inlets include curtain systems and aluminum and poly shutters.
