## Ventilation Duct Types Ducts, one of the most important components of ventilation systems, significantly increase system efficiency when selected correctly. In this article, we will examine different duct types and their applications. ### 1. Spiral Ducts **Advantages:** - Energy savings due to low air resistance - Quiet operation - Easy and fast installation - Economical price **Applications:** - Central ventilation systems - Industrial aspiration - Kitchen exhaust systems ### 2. Rectangular Ducts **Advantages:** - High air capacity - Easy installation in narrow spaces - Flexible sizing **Applications:** - Large commercial buildings - Shopping malls - Hospitals ### 3. Flanged Ducts **Advantages:** - Strong and durable connection - Ideal for high pressure systems - Easy disassembly and maintenance ### 4. Self-Flanged (TDF/TDC) Ducts **Advantages:** - Fast installation - Cost advantage - High sealing ## How to Make the Right Duct Selection? 1. **Calculate air flow** - Determine the amount of air to be transported 2. **Evaluate pressure loss** - Critical for system efficiency 3. **Examine space conditions** - Ceiling height, passage areas 4. **Determine your budget** - Material and labor costs Contact us for professional support.
