FAQ
1. What is a Duct Leakage Tester used for?
The Duct Leakage Tester is used to measure the airtightness of HVAC duct systems by detecting and quantifying air leakage. It helps ensure that ventilation systems meet design and energy efficiency standards.
2. What types of duct systems can be tested?
It can be used for testing a wide range of ductwork, including:
HVAC ventilation ducts
Air conditioning duct systems
Industrial exhaust ducts
Cleanroom air distribution systems
3. Which standards does the equipment comply with?
The tester is typically designed to meet international standards such as:
EN 12237
SMACNA duct leakage standards
ISO-related HVAC testing requirements (depending on configuration)
4. How does the duct leakage test work?
The system pressurizes or depressurizes the duct and measures airflow loss. Based on pressure difference and airflow data, the leakage rate is calculated to determine duct sealing performance.
5. Why is duct leakage testing important?
Duct leakage testing helps:
Improve HVAC energy efficiency
Reduce air conditioning loss
Ensure indoor air quality
Meet building certification requirements
