The Minneapolis Blower Door is a compact, lightweight & simple to operate building airtightness testing system. Leakage rates are calculated quickly & effortlessly using the DG700 digital Pressure and Flow Gauge.
Please note that none of BSRIA Instrument Solutions rental stock of Air tightness Testing equipment carry a UKAS accredited calibration and therefore should only be used for diagnostic purposes only. An optional UKAS accredited calibration service is available at an additional charge.
Combined with specialised accessories and complete testing procedures developed by The Energy Conservatory, the Minneapolis Blower Door is the system of choice for utility Demand Side Management programs, energy raters, HVAC contractors, builders and weatherisation professionals.

DG-700 Pressure and Flow Gauge
DG-700 Pressure and Flow Gauge contains 2 precision pressure sensors which provides simultaneous display of both building pressure and Blower Door fan flow readings. It’s specialised “Baseline” and “l/s @50” features makes it extremely easy to get quick and accurate airtightness test results. In addition, the DG-700 can be used along with a laptop computer and The Energy Conservatories TECTITE software to conduct fully automated Blower Door tests.
NOTE:- The TECTITE software requires a RS232 port (serial) port fitted to the PC.
Optional Automated Performance Testing System
The Automated Performance Testing (APT) System fully automates the Blower Door test from your laptop computer giving you the best in accuracy and convenience. The APT system automatically adjusts the speed of the fan while simultaneously monitoring building pressure and Blower Door fan flow readings. The APT System can also be configured to measure and record zone pressures during the Blower Door test.
