Blower Door – retrotec 5100
DM32X pressure gauge
The DM32X has a more streamlined and ergonomic design than its predecessor, the DM32. It features color-coded connections and a high-resolution touchscreen with real-time display of pressure value curves, giving a better picture of the process. You can also choose from several logging options. The meter features fast 3A charging and data transfer via USB-C and can be connected via Wi-Fi and Ethernet. The meter also has integrated apps for density testing and training. The display shows photorealistic images of all devices and measurement areas.
The fan
The robust fan (with a 10-year warranty on the shell) is precision calibrated, has large, easy-to-grip knobs and molded handles, and can withstand high air pressures without deforming or cracking. Thanks to its design, it converts more power into efficient airflow, resulting in lower operating temperatures. When measuring low airflows, a special perforated plate can be mounted in the outer fan ring. It is also possible to fit air flow plugs in the perforated plate, to further reduce the measuring range. Color-coded connections facilitate connection.
The aluminum frame
The aluminum frame was designed for airtightness testing in extremely tight passive houses and has square corners that provide full sealing at the four corners of the doorway. The parts are numbered for easy installation in the shortest possible time.
SmartCloth – new door cloth
Retrotec SmartCloth is a real industry breakthrough. It’s an upgrade to Retrotec’s standard door cloth with a built-in bias hose that dampens the effects of wind. SmartCloth allows for a more accurate pressure value in windy conditions. This offers advantages over traditional methods where a reference tube is placed outdoors on the ground.
Software
The delivery includes the PC software Fantestic Pro for Windows which can be used to remotely control the pressure gauge from a computer and perform both automatic and semi-automatic air tightness tests, generate automatic test reports, update the software in the pressure gauge, etc.
Included in delivery
Blower Door – retrotec 5100. Fantestic Pro software. Course in airtightness testing. See the back of the pdf-brochure under the Download tab for detailed info on all parts.
