stores and amusement centers.             It retains heated                       or cooled air within the store space at an efficiency rate                       of 60-80%, allowing only a minimum of temperature fluctuation.
                      Dust-proof effect
                      If installed in doorway of a precision machinery factory,                       or a food or clothing store facing a bus street, outside                       dirt and dust are effectively screened out, protecting the                       merchandise at an efficiency level of 60-80%.
                      Insect-proof effect
                      Most of annoying, harmful, germ-laden insects are checked;                       being unable to penetrate the powerful air curtain. Thus,                       making health and sanitation standards easier to maintain                       in grocery stores, butcher shops, fruit counters, and fast-food                       operations.
                      Deodorizing effect
                      Prevent odors from such special rooms as chemical labs,                       or vegetable preparation rooms and meat freezers in super-markets.                       Prevent automobile exhaust fumes from outside.
                      High Air Velocity
                      The high pressure produced by the sirocco fan delivers a                       powerful jet of air from the air outlet. Optimum performance                       is attained when the air inlet on the top surface is kept                       at least 50mm from the ceiling.
                      Low Noise
                      The quiet sirocco fan and newly developed, low-noise resin                       casing have reduced the noise level by and average of 10dB                       compared with conventional models.
                      Shut-out ability
                      An air curtain’s shut-out ability is determined by the air                       velocity at the center of its airflow. The powerful discharge                       of HONSHU Air Curtains enables them to maintain a high level                       of air velocity for the curtain’s efficient distance, resulting                       in superior shut-out ability
