*Our house canreach thermal insulation, sealing performance, but it also prevents aircirculation what led to accumulation of feculent and harmful gases, reduces theoxygen content of the air and affects our health, all which is that people cannot smell detected.
*Do you knowwhen the doors and windows closed, indoor air carbon dioxide how many do? Doyou know if the polluted air connect level is high, how much harm it will causeto the occupants? Do you know when the difference of temperature betweenoutdoor and indoor is large, how much energy will waste by opening windows toventilate? These questions, perhaps, you never thought or did not pay attentionbefore, or subject to restrictions on the living conditions thar can notsolved.
*According tothe survey, more than 50% respondents open windows for ventilation less than 15minutes. Although, most of the occupants are not content with their indoor airquality more or less, they still do not pay much attention to ventilationimportance. In a closed room people can’t breath well so that they have poorquality of sleep. Ordinary people will exhale 20 liters of carbon dioxide whichoccupy 4% of the exhaled gas per hour, while the carbon dioxide content in thefresh air is 0.03 to 0.04%. If the atmospheric carbon dioxide content of ismore than 0.1%, it is slightly polluted. Therefore , the scientific ventilationis very im
· Design:
· The motor isattached to the body of the fan by two quick release clips which enables themotor to rotate to provide connection for confined spaces and removal for maintenancewithout removing the whole fan or duct. All models have an option of standardwhich has a two speed motor or overrun timer option variable range of 1 to 30minutes.
· Motor:
· The singlephase ball bearing motor has two speeds and is equipped with standard thermaloverload protection (STOP) with automatic restart. Motor protection rating IP44and are fully speed controllable. Complies with part F building regulations anddesigned for ambient temperatures -20~60°C. Supply voltage 110V~380V, 50/60HZ.
· Mounting:
· The fan canbe mounted in line or at either and of the duct run and at any angle.Horizontally or vertically. All fans can be mounted in parallel to increase thevolume of air or in series to increase the pressure. The casing is fitted witha mounting plate. The mounting box can be rotated to be installed in anypositon for easy installation and connection.
