Description
UB1102, UB1103
Blower
CONCEPT AND MAIN APPLICATIONS
Models UB1102, UB1103 Blowers are successors of UB1100, UB1101.
Their output air volume is 4.1m³/min. over the predecessors 2.8m³/min.
The other features are as follows:
• Ergonomic designed handle with elastomer for more comfortable
and controlled operation
• Self-standing design enables stationary use, easy storage and upside-down
standing
The specification difference between UB1102 and UB1103 is;
