Farm building fan GV45 Series

for greenhouseextractionwall-mounted

HHB gas heaters and HHO oil heaters with open combustion produce CO2 as well as heat. This is a positive addition considering plants need CO2 for optimal growth. However, too high a concentration of CO2 in the greenhouse can also be harmful for the crops. So it’s important that CO2 can be extracted. This is of course possible by keeping windows open for a longer period, but this is not always desirable in cold periods when heaters are on for a longer time and the CO2 concentration can accumulate to above the desired level. In this case, gable fans are the ideal solution.
