Unfortunately nothing with approximately 140m³ in 1min when it comes highly stem the maschiene 40m³ in the minutes. And now for just over a week in the rumpus room of fog output is slower and louder, think the Maschiene it will not make long. It also does not like the Maschiene when. Only times as a little smoke output from 1sec makes for nachzunebeln, and then goes back into the 7min. heating phase. UPDATE --- 09/24/2014 --- So now the pump has its Service set complete! :-( I would recommend anyone this Nebelmaschiene unfortunately, to be a no exchange pump available, so that you could continue to use the device. comparable pumps, which can be purchased on ebay cost does not include shipping ~ 20euro! but am going now but a higher-priced fogger down, and to inquire in advance for exchange pump and other wear parts.
