Assembling drawing of blower package
Standard supply of scope
1. bare shaft blower
2. relieve valve
3. slime type wafer check valve
4. inlet silencer(with air filter)
Damping silencer is adopted for mainly eliminating the airflow noise at the inlet of the blower. It is welded by outer cylinder, inner cylinder, flange and other parts, and the sound absorption material is placed between the inner and outer cylinders for light weight,low resistance and better noise reduction effect. The silencer is made of A3 steel.
5. discharge silencer
6. Blower and motor base (with belt cover)
7. rubber flexible joint and shock absorber
8. motor pulley
9. pressure meter
10. V-belt
11. bolts and nuts and other connection parts
12. electric motor
Optional parts such as acoustic enclosure, control cabinet, auto-start valve and spares are available.
