In order to achieve the desired performance results in the ventilation system and to ensure comfort and hygienic conditions, duct leak tightness tests should be carried out during the installation of ventilation ducts.

• Increasing energy efficiency
• Reduction of energy cost
• Reduction in operating cost
• Reduced equipment maintenance cost
• Increased equipment life
• Ensuring comfort conditions
• Ensuring hygienic conditions
• Ensuring indoor air quality
• Duct leak test is important in terms of ensuring the design conditions of ventilation systems.

If the air leaks in the ventilation duct are not taken or removed, the air plant will not be able to provide the required amount of air. Air duct sealing tests should be started immediately with the start of the duct production. Thus, possible problems should be identified at the beginning of the work and precautions should be taken and money and time should not be wasted by dealing with corrective activities in the future. The important variables affecting the amount of leakage can be listed as follows;
