 Application

• Type VSD35-3-AZ slot diffusers are used as supply and extract air combinations in comfort zones
• Angled one-way air discharge for turbulent flow (mixed flow ventilation)
• High induction results in a rapid reduction of the temperature difference and airflow velocity
• For variable and constant volume flows
• For supply air to room air temperature differences from –10 to +10 K
• For room heights up to 4 m (lower edge of suspended ceiling)
• For horizontal installation into walls and bulkheads

Special characteristics

• Individually adjustable air control elements to meet individual local requirements
• High induction results in a rapid reduction of the temperature difference and airflow velocity
