The development of the Minneapolis Duct Blaster® has revolutionized performance testing of forced air distribution systems for builders and HVAC contractors. The Minneapolis Duct Blaster is a calibrated air flow measurement system designed to test and document the airtightness of forced air duct systems in both houses, light commercial buildings and rooms / enclosures such as hospital operating suites.
The Duct Blaster fan is connected directly to the duct system in a house, typically at a central return, or at the air handeling unit. With the remaining grilles/outlets temporarily taped off, duct airtightness is measured by either pressurizing or depressurizing the duct system and precisely measuring the fan flow and duct pressure.
Flow Accuracy: +/- 3% or 1 CFM, whichever is greater (using DG-700 micromanometer).
Calibration: Meets ASTM Standards E779-03 and 152, CGSB-149.10-M86, EN 13829 and ATTMA TS1.
Power: 110V or 220V.
NOTE 110V model only available for hire.
