The Design-Aire LP is the smallest model in our line of fan-filter units.  The sleek design of the stainless steel housing is ideal for pharmaceutical applications requiring frequent wipe downs.  This compact model, however, is no step down from our standard Design-Aire as it contains nearly all the same great features.


  • Easy Installation
    The 10.75” height and light-weight housing of these units make them easier to slide into ceilings. The 3-prong electrical cord allows them to be plugged into standard 115V outlets.
  • HEPA Duration
    The variable speed control helps increase HEPA filter life by allowing the motor speed to be increased as the loading on the filter increases. This keeps the airflow consistent and results in fewer filter changes.
  • Energy Costs
    Each unit only uses a maximum of 1.08 amps.
  • Stainless Steel Housing
    Durable stainless steel housing has a smooth finish for easy cleaning.
