1.4.2 Safety Regulations for the Blower
1) The blower cover will be heated up during operation. Keep hands away high
temperature blower cover to avoid hands burning.
2) Motor under load current will be varied with air pressure of the blower.
Overload relay should be used and keep motor working current within
full-load current to avoid motor burning out.
3) Air filter is used to keep off dirts, particles, fibres, and water drops. Clean the
filter about once a week.
4) Clear up inside and outside of the blower regularly. If there are too much dirts
accumulated on the blower, the function of the blower will be affected, such
as temperature rising, reduced air volume and higher noise level due to
vibration. All the above factors are liable to cause mechanical problems.
5) The bearing, seal ring and silencer are all consumable parts. They should be
replaced after a period of time. And also the fans, covers, and metal grids
need to be changed when necessary.
6) If the blower can not work properly or makes loud noises, please turn off the
power supply to have a check.
