Description
TEC Minneapolis Duct Blaster® System with DG-1000
Need to test your ducts for leakage? Use the original Minneapolis Duct Blaster® for quick easy and accurate results. Performance testing of HVAC duct systems is now required across a large part of the country as duct leakage accounts for significant energy losses, comfort and IAQ problems. Identify and quantify these problems quickly and easily by connecting the Minneapolis Duct Blaster® to a central return or the air handler cabinet, tape off or cover the remaining register or grills and use the Duct Blaster® to measure leakage or air tightness by either pressurizing or depressurizing the entire duct system. Airflow through the fan is measured by pressure drop with a high accuracy DG1000 manometer.
Duct air-tightness measurements are used to diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, and certify compliance with duct leakage standards such as California's Title 24 Building Energy Efficiency Standards.
Key Features & Benefits
- The lightweight Duct Blaster® fan weighs just 7 pounds, but delivers enough air flow (an amazing 1,500 CFM) to test the leakiest duct systems.
- Quick and accurate air-tightness measurements from 20 - 1,500 CFM.
- Compatible for both pressurization and depressurization testing.
- The Duct Blaster® can be easily used in new construction applications where a Blower Door can't be used (e.g. before sheet rock is installed).
- The Duct Blaster® can also be used as a powered flow hood to accurately measure air flows through the air handler fan, registers and grilles, and exhaust fans.
- Includes DG1000, high accuracy digital manometer and necessary hoses to connect system
- Variable fan speed control (solid state).
- Padded nylon carrying case with shoulder strap.
- 2 Year Manufacturer's Warranty.

TEC Minneapolis Duct Blaster® Overview
Software / App
Download the TEC Gauge App for your Android or iOS devices!
TEC Gauge is a free mobile app that provides wireless control and display of DG-1000, DG-700 and DG-500 Pressure and Flow Gauges. TEC Gauge's capture feature lets you store and share readings from your gauge.
This app connects to the gauge through a WiFi network (DG-700 and DG-500 gauges require a TEC WiFi Link).
Features Easy to use cruise control for the blower door fan and Duct Blaster® fan. Baseline feature for airtightness evaluation. Displays airflow values for all TEC devices.
Capture feature allows for storage and sharing of readings from the TEC gauge. Captured readings can be labeled, sorted and sharing using file sharing apps on the mobile device. Capture readings can be shared in either text or xml formats.
