ROOF VENTILATORS Models LUD LUB LUBMO LUBSH LUD Upblast direct drive model LUD is available for generalpurpose exhaust. Direct drive fans are an ideal choice for installations where service and maintenance are made difficult due to limited access. The LUD can save on service costs incurred through sheave, belt and bearing maintenance. LUB Standard duty upblast belt driven model LUB is available for use in clean air applications requiring the adjustable performance of a belt drive fan. Motor and drives are located below the fan, inside the roof curb for access from inside the building. Model LUD LUBMO The belt driven LUBMO offers the same performance flexibility as the LUB, but with the motor located out of the airstream for easy inspection and service from the roof. The motor cover is easily removable making the motor and drive components accessible without moving the fan. LUBSH The LUBSH is specifically designed for smoke control applications. It is belt driven with the motor located remotely out of the airstream and the bearings and drive components protected from the elevated temperatures of the airstream. It is certified to carry the UL/cUL listing for smoke control systems and was tested for 500 F for 4 hours or 00 F for 1 hour.
