Description

Gas blower system iNR77 from ebm-papst is a solution to the ever-increasing challenge of gas blowers and their parts becoming very compact. This solution was achieved by incorporating the latest electronic gas valve F01 in the NRG77 gas blower's housing. This has made it possible to employ only two components - blower housing featuring valve and gasket and venturi element with side cover. This is a significant reduction from the previous five, which included venturi nozzle, blower housing, valve side cover, valve housing, and gasket.

This design requires a volume of 150x180x155 mm, which is only 80% of the NRV77 system (210x165x155 mm). The iNR77 uses the similar principle as NRV77. The open safety module and the stepper motor module are used for drawing gas into the venturi nozzle. Here the gas is combined with the air, drawn into the fan and put into the gas boiler's burner.
