Capacity blower motor [kW]
1) Air pressure switches should be selected to have a setpoint ranging from 2-10 mbar.
2) Single phase blower motor available.
3) The EB Valupak II requires an external blower with flat characteristics.
4) As an alternative blower U/HC142 (0,18 kW) can be used. Performance is the same as with UMI300 blower.
5) Use of the standard round air inlet filter will cause a ± 15% capacity reduction. UMI blowers are not suited for filters.
6) When firing in open air. Firing in a cross flow shortens the flame.
7) Sound data refers to open firing burner in free field of conditions, at maximum capacity.
