/34 | OPTIMA-S-FC...BM Description OPTIMA-S-FC...BM is a variable air volume controller with or without an insulation. The product is intended to control the flow volume of supply or return air. The product is installed into rectangular ducts. The product is ideal for all applications, where a variable air flow volume in ventilation, cooling or heating is required (offices, hotel rooms, meeting rooms, health care premisses, residentials, etc.
/34 | OPTIMA-S-FC...BM Design OPTIMA-S-FC...BM consists of a galvanized steel sheet casing, aluminium profile blades with rubber gaskets and a modular VAV control device. OPTIMA-SI-FC...BM is equipped by an insulation for sound reduction. The insulation is a 19 mm thick closed cell foam mat, protected by galvanized steel sheet. The casing contains a robust flanged mounting frame for installation into ducts. The blades are opposed action.
