Product Description
The Minneapolis Blower Door 2-Fan System with 2 DG-1000 Gauges is a high-capacity building airtightness testing system for professionals who need more airflow than a single-fan setup can provide. Designed for commercial buildings, large homes, multifamily projects, and advanced envelope diagnostics, this kit combines two Model 3 blower door fans with two DG-1000 pressure and flow gauges for coordinated multi-fan testing.
This BD3-KIT-020 configuration includes the commercial aluminum frame setup, a two-hole red nylon panel, two Model 3 fans, two DG-1000 gauges, fan speed controllers, flow rings, commercial hose kit, gauge cases, fan control cables, and supporting accessories. The system delivers up to 12,600 CFM total system flow at free air, making it suitable for larger air leakage tests where a single fan would be undersized.
The DG-1000 gauges add modern touchscreen control, Wi-Fi, Bluetooth, USB, and Ethernet connectivity, rechargeable lithium batteries, fan speed control, magnetic mounting, and compatibility with TEC equipment and software. TEC also lists an Overview Booklet and Brochure on the product page; I do not see a separate dedicated spec sheet listed, but the product page itself includes detailed specifications and kit contents.
