infiltrationstester

Infiltrationstester, also known as an infiltration tester or infiltration gauge, is a device used to measure the rate at which air or other gases can infiltrate a building or structure. This measurement is crucial for assessing the airtightness of a building envelope, which is a key factor in energy efficiency and indoor air quality. The device typically consists of a fan that creates a controlled pressure difference across the building's envelope, while sensors measure the resulting airflow rate.

Infiltrationstesters are commonly used in the construction and building maintenance industries. They help professionals identify and address leaks in the building envelope, such as cracks in walls, gaps around windows and doors, and poor sealing of HVAC systems. By quantifying the infiltration rate, these devices provide valuable data for improving building performance, reducing energy consumption, and enhancing occupant comfort.

The testing process involves placing the infiltration tester on the exterior of the building and connecting it to a duct or hose that leads to the interior. The fan is then activated to create a pressure difference, and the airflow rate is measured. The results are used to calculate the infiltration rate, which is typically expressed in units such as cubic meters per hour per square meter of building envelope area (m3/h·m2) or air changes per hour (ACH).

Infiltrationstesters are available in various sizes and configurations to suit different building types and testing requirements. Some models are portable and can be easily moved between locations, while others are designed for permanent installation. Advanced versions may include features such as data logging, remote monitoring, and integration with building management systems.

Overall, infiltrationstesters play a vital role in the assessment and improvement of building performance. By providing accurate measurements of infiltration rates, these devices help professionals make informed decisions regarding energy efficiency, indoor air quality, and building maintenance.
