Model 45 Placement


  • Install electrical circuit(s) and outlet(s) in accordance with national and local electric codes 
  • Outlets should generally be mounted vertically unless a “twist/locking” type is being used
  • Wall switch may be installed in circuit to disable power and prevent electrical hazards when servicing
  • Confirm electrical continuity of Air Pear on the ground before permanently mounting in the ceiling


  • The Air Pear performs best when installed such that the air column/exhaust from the nozzle is unimpeded to the floor
  • Mount 12-18 inches off ceiling deck to intake
  • Use professionally installed hardware, capable of supporting a minimum of five times the weight
  • Hardware to hang the unit includes but is not restricted to: Hooks, chains, cables, carabiners, bridle rings, beam clamps and bolts
  • Density of the placement is a direct relationship to the effectiveness, performance and savings
  • Floor plans, mezzanines, office locations, machinery, people placement, plumbing, lighting, duct work, electrical systems, natural light/air systems, cranes, doors, windows, ventilation and fire suppression systems are all factors in properly locating the Air Pear system within the ceiling


  • PSP4 model capable of covering up to 1200 ft² or a 40 ft coverage diameter with a mounting height up to 38 ft
  • PSP2, EC, and EL models capable of covering up to 1500 ft² or a 44 ft coverage diameter with a mounting height up to 45 ft


  • Designed to operate 24 hours-a-day, 7 days-a-week to maintain thermal equalization/humidity equalization
  • Use optional speed control to fine tune RPM if needed


  • Frequency of cleaning will vary by application and environment
  • You may clean the plastic housing with a damp warm cloth, using mild household detergents
  • Do not use petroleum products, thinners or solvents to clean any part of the Air Pear
  • If the Air Pear system fails, contact manufacturer
