Can I use a Duct Blaster fan to conduct airtightness tests of houses?

Yes. The Duct Blaster fan's 1,350 cfm (cubic feet per minute) air flow capacity at 50 Pascals will allow you to conduct a complete airtightness test on most houses built to energy efficient airtightness standards. For example, the Duct Blaster fan can generate a 50 Pascal test pressure in a 3,000 square foot house built to a performance standard of 3.0 air changes per hour. For tighter houses (1.5 air changes per hour) the Duct Blaster fan can test a house up to about 6,000 square feet. We even make a nylon door panel for use with our adjustable aluminum frame that is sized just right for the Duct Blaster fan.
