Retrotec US1102 US 1102 Blower Door Air Leakage Test System

The Retrotec US 1102 features a calibrated Model 1000 fan, a tight fitting cloth door panel & the DM32 gauge.

Retrotec's US1102 is the by far most economical method for blowing large volumes of air in order to test Houses, Small Commercial enclosures or apartments.

The US1102 utilizes the DM-32 gauge which is more advanced than the competition & perfect when operating your blower door system manually or on full automatic using your computer & FanTestic Software. When pressure testing fans are separated with a large amount of distance, the Retrotec DM32 is your best bet since it runs over Ethernet cables for practically unlimited distance.
The DM32's WiFi adds a wireless feature which is not generally required for large set-ups since wired configurations have higher dependability but it works well when the distance are line of sight.

You can also execute data logging automatically from your fan & control your gauge remotely from your laptop. With the new recommended five year calibration interval for the DM32 you will avoid yearly calibrations.

With a 3/4 horsepower motor Retrotec's Model 1000 produces 6300 CFM maximum through the 22 inch diameter inlet which makes it highly ideal for measuring both residential & small commercial building
air leakage. The fan also has a knob for controlling the speed at your fan manually & a convenient input port which provides automatic control with a Digital Gauge made by Retrotec. A status light located beside the input port indicates if the gauge has established a proper connection. The additional control port enables multiple fan linking so they can be operated from a single source.

The fan's shell features double riveting with gussets, an innovative design which prevents the loss of blade tips. Incredibly stable mounting with 8 points perpetuates the fan's alignment even under extremely stressful testing conditions. The attachment points are permanently
molded so nothing can become loose & the motor mounting holes won't tear out.

The fan also uses a proprietary speed controller which evens out the power distribution, reducing noise & energy loss.

Retrotec durability is backed with the industry's longest no fault warranty available - a full ten years for the fan shell.

Calibrated range configuration allows 1 fan to perform testing for wide variety of enclosures - from super tight to super leaky. The fan also includes 11 different flow ranges which provide precision results for the largest enclosure volume ranges. All of Retrotec's fans are manufactured with space age, extremely durable plastic foam making them both tough and lightweight. They are easily reversible - to switch between pressurizing and depressurizing the enclosures, simply flip your fan around inside its panel.

Simply run one Ethernet cable from your testing area to your laptop in order to control testing with no extended umbilical required.
