Product Description
The Minneapolis Blower Door 3-Fan System with 3 DG-1000 Gauges is a professional multi-fan testing system for commercial buildings, large residences, multifamily properties, and advanced enclosure testing projects. It is designed for situations where a single- or two-fan blower door setup does not provide enough airflow capacity for the building being tested.
This BD3-KIT-030 configuration includes three Model 3 110V fans, three DG-1000 pressure and flow gauges, an adjustable commercial aluminum frame, a three-hole red nylon panel, fan controllers, flow rings, fan caps, tubing, gauge accessories, cases, and TEC software access. With a maximum total system flow of 18,900 CFM at free air, this kit is aimed at high-capacity building airtightness testing, including commercial testing protocols such as Army Corps, NEBB, and other standards-based procedures.
The three included DG-1000 gauges provide touchscreen pressure and flow measurement, fan speed control, Wi-Fi, Bluetooth, USB, and Ethernet connectivity. For contractors and building performance teams, this system offers the airflow capacity, measurement tools, and commercial frame setup needed to perform demanding air leakage diagnostics with a complete multi-fan configuration.
