The 6311 Blower Door System has three Model 6000 Calibrated Fans in one Large Cloth panel door frame system. It will blow large quantities of air to test Commercial, Multi-Family or High Rise buildings. But has 1 hp fans, not ¾ hp fans found in all other blower door systems. In addition to power, the other advantage is speed stability which is near perfect since it uses variable frequency drives to power the fan motors.
The Model 6311 uses the DM32 which more advanced than any competitive gauge and ideal when running the 6311 manually or fully automatically using a computer and the optional Multi-FanTestic Software. When test fans are separated by large distances, the DM32 is the best choice since it will run over Ethernet cable for essentially unlimited distances. The DM32 WiFi adds the wireless feature that generally is not needed for large set ups since wired connections are more dependable but works very well when distances are line of sight.
You may also run automatic data logging from multiple fans, and remote gauge control from a laptop. With our new 5 year recommended calibration interval on the DM32, you will have the peace of mind knowing that yearly calibrations are a thing of the past.
Calibrated range configurations allow one fan to test a wide range of enclosures, from super leaky to super tight. This high output fan includes 9 flow ranges to provide accurate results over the widest range of enclosure volumes. All Retrotec fans are made with extremely durable space-age hard plastic foam, which makes them both lightweight and tough. They are also easily reversible: to switch from pressurizing to depressurizing your enclosure, simply flip the fan around in its panel.
Run only a single Ethernet cable from test area to the laptop to control your test, no extended umbilicals needed.
