New codes (UL 705 DEDPV and IRC-2015) require Dryer Booster Fans to have a additional safety features and have a panel at the dryer that show that the fan is working properly and warn if there are any errors.  The LB2 meets UL 705 DEDPV & International Residential Code (IRC-2015) Requirements.  These requirements will need to be met all over the country by the end of 2016, and are already in place in certain areas already.   Buy this Dryer Booster Fan LB2 to make sure you are up to code.

A dryer booster fan helps your dryer dry your clothes more efficiently - by up to 50%.  A booster fan is typically used in long dryer ducts.  Any dryer duct longer than 25 feet can increase your drying times and energy use, and increase your gas or electric bill.  A long dryer duct run also increases the lint build-up and the potential for a duct fire.   The 50 watt motor is not exposed to heat, lint or moisture.  It includes a 115 VAC cord for automatic operation.

The LB2 is an advanced dryer booster fan, it has increased safety by alerting you to different dryer conditions, such as excessive dryer duct temperatures.  Another fantastic safety feature is that it will alert you if there is a blocked vent or fan malfunction.  The LB2 is a great choice for a dryer booster fan because the lint blitzer blower wheel repels lint. 

The LB2 has an advanced actuation control with improved pressure sensing that reacts to both duct pressure and temperature to consistently operate in sync with the dryer.  The LB2  has a status panel that mounts in your laundry room to show you the status of the dryer booster fan is working.  This dryer booster fan can be installed horizontally or vertically.
