Leak Checker/Air Leakage Diagnostics Fan
Achieving an airtight construction alongside an appropriate well balanced ventilation system can
deliver a more comfortable home environment and significant energy efficiency benefits.
The BTS Leak Checker can minimise uncontrolled air leakage within buildings, by helping users to
identify unwanted air leakage paths. The fan is designed to be window mounted, and offers simple
operation through a mobile app. The BTS Leak Checker is highly recommened as a diagnostic tool, to
be used at any stage of a retrofit or new build project.
The simple window mounted unit allows site teams to test for air leakage throughout the building. This
helps to improve build quality and compliance test pass rates New build Existing homes and retrofit Air leakage can account for as much as a third of total heat loss. Finding and remedying those leaks can lead to considerable energy savings and comfort gains.
Easy to operate:
The fan is very easy to operate, making leakage path diagnostics accessble to all.
Save time and costs
Run the fan during works and before your compliance testing to be confident of a first time pass whilst reducing the need for costly rectification and remedial works.
Identify leakage paths
The fan creates a pressure difference large enough so that air leakage paths can be felt with your hand or visualised with a smoke pen or thermal imaging camera.
The fan will provide an indication of overall leakiness and the level of progression made by your sealing interventions.
The Leak Checker fan can be used before or after a Pulse air leakage test, allowing diagnostics and sealing works to be carried out independently.
