Retrotec 5101 Blower Door System

The Retrotec 5101 Classic Blower Door System represents the full development of the very popular US1000 blower door. Boasting the nearly indestructible 5000-series fan, the Retrotec 5101 is perfectly suited for testing most residential and small commercial buildings. The fan can move up to 6400 CFM, and can be controlled manually by a knob on the fan housing, or automatically by the DM32 Digital Manometer. Manual control allows the blower door to be used for leak detection and air sealing without setting up the manometer. The 0.75 horsepower fan is enclosed in proprietary plastic case that is so tough it’s backed with a 10 year warranty. The Retrotec 5101 Classic can be set up to pressurize or depressurize to any user defined pressure, and can run all major test standards. The fan can be configured for 11 different flow ranges so you will always have the best options, whether the house is tight or leaky. The adjustable aluminum door frame will accommodate doors up to 42”, and features corners designed to seal off the last little bit leakage around the door.

The new Retrotec DM32 Manometer offers two differential pressure channels and a beautiful 3.2” color touchscreen. The intuitive interface allows manual or fully automated control of the blower door test. Read pressure and flow in any combination of the many available units. Eliminating the need for a computer or time consuming equations, the Retrotec 5101 and DM32 performs real time calculations, from CFM/sq ft to ACH/h. The DM32 firmware can even be updated over the internet, without the hassle of returning the gauge just to receive an update.

The included Fantestic Lite software for Windows will run a fully automated blower door test, collect all relevant data, and generate reports conforming to the chosen test procedure. Optional Fantestic Pro software will allow customizable reports in MS Word format, and can export test data to MS Excel. Also included with the Retrotec 5101 Classic is the full DM32 Software Suite: DM32 Configurator Software to update settings and firmware, the Data Logger Software for recording and exporting pressure readings, and the innovative Retrotec Virtual Gauge for PC. Virtual Gauge can be used to control and reflect a live gauge to the PC for monitoring or training purposes. Or if a live gauge is not on hand, Virtual Gauge can simulate a DM32 gauge for demonstration and teaching applications.

The DM32 WiFi Digital Gauge allows for wireless control from a PC, smartphone, or tablet. Applications are available for Android and iOS, and the wireless connection can be made directly between the device and the manometer. No external network is necessary for wireless functionality. Once connected, the phone or tablet can mirror the DM32 display and offer full control of the manometer. Run complete tests from your phone. Or monitor combustion appliance zone (CAZ) pressure or other building pressures as you walk around a house. The DM32 WiFi Digital Gauge brings both greater flexibility and new diagnostic capabilities to your blower door and manometer.
