Description
TEC Minneapolis Blower Door with DG-1000
The blower door fan consists of a molded fan housing with a 3/4 horsepower permanent split capacitor AC motor. Air flow through the fan is determined by measuring the pressure at the flow sensor which is attached to the end of the motor. When the fan is operating, air is pulled into the inlet side of the fan and exits through the exhaust side (a metal fan guard is bolted to the exhaust side of the fan). The blower door fan can accurately measure airflow over a wide range of flow rates using a series of calibrated flow rings which are attached to the inlet of the fan.
Recommended for:
- HVAC Professionals
- Weatherization
- Energy Raters
- Building Contractors
- Home Inspectors
Features:
- DG-1000 Bluetooth wireless manometer
- Lightweight, rugged, injection molded fan housing
- Precise, stable flow measurements without the need for gauge dampening
- The Model 3 Fan provides quick and accurate flow measurements from 300 to 6,100 CFM (includes Flow Rings A and B)
- Optional Flow Rings C, D and E will measure down to 11 CFM
- Variable fan speed control (solid state - cruise control compatible)
- Operates on 110V/60 Hz
New for the DG-1000
- All DG-1000 have a 4-year calibration cycle
- All new DG-1000 (since Nov 21) have a USB-C port (for charging and communication) replacing the barrel jack charger and Micro-USB port
- With firmware upgrade DG-1000 can be a stand-alone pressure logger

*Typical Conditions are a temperature range of 54 to 90 degrees F, and a two year calibration interval.
**As Calibrated Accuracy is +/- (0.3% of reading + 0.05 Pa) under controlled conditions of 67 to 77 degrees
F, four month calibration interval, and pressure readings averaged for 5 seconds. All gauges are verified to
meet this specification at all calibration pressures.
***For use at temperature conditions outside the
typical conditions in Note 1, or the as-calibrated range in Note 2, add an additional 0.037% of pressure
reading per degree F over the stated range.

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.
