Features:
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
