Seiho's popular SpotDiffuser is now available with the Condensation Control Air Guide - PK-K! The PK-K's Air Guide is designed to lead the air to the diffuser's outer surface, and help reduce the area where condensation may occur. The Air Guide is made of low thermal conductance material with the dual airflow design (Patent Pending). The PK-K is virtually condensation-free and is perfect for high humidity areas such as gyms, kitchens and food processing facilities.
