THE CIRRUS IS A HANDHELD DEVICE THAT IS SAFE AND USED IN VARIOUS APPLICATIONS. THE FEATURES OF THE CIRRUS AIR FLOW DETECTOR USES VAPOR TO SHOW AIR LEAKS, AIRDUCT AIR FLOW, HOOD VENTS, CEILING FAN AIR MOVEMENT, CHIMNEY DRAW, AIR LEAKS AROUND DOORS AND WINDOWS AND SO MUCH MORE.
Virtually all houses, even yours, exchange indoor air with the outdoors. There are two reasons for this: First, a house will always have some leaks (air passages), however small, that connect the inside with the outside. These might include larger gaps around pipes, vents, and chimneys, and smaller cracks at places such as the join between the window frame and the wall. The second reason for air exchange is that there are temperature and pressure differences between inside and outside — air works hard to move from regions of high air pressure to ones with lower air pressure.
Consider a two-story house with a basement during winter. We all know that the warmest air tends to rise to the top floor, and that it can be several degrees warmer near the ceiling than in the basement. The warm, buoyant air is at a higher pressure than the cold air outside, and will want to move up and out, through windows, ventilation openings, and leaks in the walls, ceiling, and roof. Downstairs and in the basement, low-pressure cool air rushes in to replace the rising air in an attempt to maintain pressure balance. This natural upward current through the house is called the stack effect. The same principle allows smoke and hot gases to rise up your chimney. In most houses, the amount of air that enters the house increases when it’s windy and cold. When it’s warm outside, the stack effect is much weaker or reverses.
Replacement of stale inside air with fresh outside air is called ventilation. Ventilation can occur naturally, aided by the stack effect and open windows, or mechanically, with the use of a fan, or series of fans, that pull air in or out of the house. If air movement between inside and outside is accidental, we call it infiltration.
During a storm we lost power. We used the Cirrus for the lights plus charge our cell phone.
I love being able to check for air leaks around the house. My husband was thrilled I figured out our doors had a huge draft
Air flow checker, lights and a power bank charger…? Our Cirrus stays close by all the time
