What makes Retrotec Blower Doors different?

Retrotec systems are built using a high-impact polycarbonate shell rather than metal or foam. This space-age material makes the fans incredibly lightweight yet virtually indestructible—they won't dent or bend if dropped. Additionally, their sleek design allows for tighter stacking and easier transport in crowded work trucks.

What are the advantages of the DM32X gauge?

The Retrotec DM32X is a touchscreen digital manometer that serves as the "brain" of the operation. It features built-in WiFi and Bluetooth, allowing it to connect directly to smartphones for automated testing. Its color display provides real-time visual feedback, and it can automatically control the speed of the fan to hit specific pressure targets (like 50 Pascals) without manual adjustment.

How does rCloud software help technicians?

rCloud is Retrotec's automated testing app. It connects to the DM32X gauge to geolocate the test site, automatically run the fan to meet code-required pressures, and generate a secure, compliant report instantly. This eliminates manual data entry errors and allows you to email the test results to a builder or homeowner before you even leave the job site.
