One-Stop HVAC Fire Ventilation Solution | Fire Damper, Air Grille, Silencer & Fan — Silver Star

Silver Star Environmental Tech specializes in HVAC ventilation and smoke exhaust equipment, offering a one-stop solution covering four core categories: fire dampers, air grilles, silencers and fans. Our fire dampers are available in both 70°C and 280°C ratings, sealing tightly to block smoke and flames without air leakage — cutting off ventilation ducts the moment a fire breaks out. The aluminum alloy louver grilles are precision-built with adjustable blades, delivering even, smooth air distribution for offices, shopping malls, factories and parking garages. Silencers and plenum boxes adopt micro-perforated noise reduction technology, keeping mechanical rooms and duct shafts quiet even when the fans are running at full speed. The fire smoke exhaust fan withstands 280°C continuous operation — high airflow, low noise and lower energy consumption — rapidly clearing smoke to buy precious time for evacuation. From dampers to grilles, from noise control to air delivery, Silver Star backs every HVAC fire-protection project with a complete product line, reliable quality and refined workmanship.
