The Leak Checker diagnostics fan aims to complement our low-pressure Pulse air permeability measurement system by helping users to locate and address key or unwanted air leakage paths.
The kit consists of a highly portable fan that is hook mounted onto an extendable rod. This bar is then telescopically fixed across any window opening. The opening around the fan mounting and the window are then sealed up using the sheet and clamps provided in the kit. The fan is then connected to an electricity supply via a standard 3-pin plug and to any mobile device from which it can be controlled via a web browser.
When switched on the fan provides an airflow of up to 2042m³/h which creates a pressure difference (either negative or positive) within the room. This pressure difference is great enough to enable air leakage paths to be very easily felt with your hand or visualised with a basic smoke pen or thermal imaging camera.
The fan itself measures just 295x300x81mm and the whole kit weighs less than 4kg making it highly portable. The operation is incredibly simple and the mounting rod easily extends to fit virtually any standard sized windows.
It’s not intended as a measurement instrument in its own right but, instead is designed to complement any air tightness test by identifying the key leakage points as stipulated under PAS 2035 Section 8.5.1. This makes it an ideal piece of kit to keep in your PAS 2035 compliance armoury.
