Noise is the number one problem for axial fans that are used for electronic cooling. It is generally caused by vibration between the housing and fan.To prevent this problem, we have developed a method that eliminates noise and makes mounting effortless. With the patented rubber elastic sleeves, you can fasten axial fans without screws, quickly and safely with four mushroom formed pegs on a mounting plate or housing wall.
ADVANTAGES:
Eliminates transmission of vibration from the fan to the housing and
reduces noise up to 9db.
Fast, simple and safe screwless mounting and remounting.
Labor saving device with less cost through shorter mounting times.
Protects the fan against vibrations and thus increases the life.
Sleeves and accessories are available for fans of 40mm to120mm and fit many axial fans
from various manufacturers.
