If the blower door measures a CFM50 leakage of 1,333 then the equation would be 1,333 cubic feet per minute times 60 minutes divided by the volume of 16,000 cubic feet to equal 5 air changes per hour. The home therefore has an infiltration rate of 5 ACH50 (5 air changes per hour at 50 Pa test pressure). Savings on test equipment. Fluke promotions, Flir offers, Tektronix and more!

The Minneapolis Blower Door has long been recognized as the best designed and supported building airtightness testing system in the world. Combined with specialized accessories and testing procedures developed by The Energy Conservatory, the Minneapolis Blower Door is the system of choice for utility In 2012, the International Energy Conservation Code (IECC) started requiring residential construction pass an air leakage–rate test, better known as a blower-door test. My area of the country mandates test results at or below three air changes per hour at the test pressure of 50 pascals (3 ACH50). In warmer climates, 5 ACH50 is typical. For a thorough and accurate measurement of air leakage in your home, hire a qualified technician to conduct an energy assessment, particularly a blower door test. A blower door test, which depressurizes a home, can reveal the location of many leaks. A complete energy assessment will also help determine areas in your home that need more insulation. Minneapolis Blower Doors DG08-KIT-001 Specifications: Number of Independent Pressure Channels: One: Digital Communication: Bluetooth Low Energy, USB 2.0: Accuracy 1,2: 0.9% of pressure reading or 0.00048 in. H 2 O (0.12 Pa), whichever is greater: Display Resolution: 0.001 in. H 2 O 0.1 Pa for readings up to 999.9 Pa 1 Pa for readings over 1000 A blower door test is a machine used to calculate airflow between the interior and exterior of a structure, measure the airtightness of buildings, and identify spots where air is leaking through a building envelope. This test ensures a certain level of energy performance and is often used when a project team is aiming for a performance-based Optional Flow Rings C, D and E will measure down to 11 CFM. Variable fan speed control (solid state – cruise control compatible). Both 110V/60 Hz and 220V/50 Hz models. This Model 3 Minneapolis Blower Door system includes a single fan, the DG-1000 pressure and flow gauge with Cruise Control, and the adjustable aluminum frame and nylon panel. 2011: Retrotec was the prime developer of the large building airtightness testing Protocol for the U.S. Army Corp of Engineers. 2013: Retrotec released the first Touch Screen WiFi gauge leaving behind all competing gauges. 2015: Retrotec produces 5 test fans, 5 door panel systems and custom software. New applications now complied with every What Do The Blower Door Test Results Mean? ACH @ 50 pascals: ACH or “ Air Changes Per Hour” at 50 pascals measures how many times per hour that the air in your home will be replaced. For example, ACH5@50 means that at a test pressure of 50 pascals, the total volume of air in your home will be replaced 5 times in one hour. y8BiGq.
