A main body with a steady flow loop device BDK62 main fan, so characteristic curve without hump blower fan, avoid dangerous surge. FKZ Ventilator host all of the upper and lower two-division structure. Characteristic curve given in the specification is based on the gas temperature t = 20oC, the gas density ρ = 1.2kg / m3, the atmospheric pressure Pa = standard condition 101325Pa made of. When using a non-standard state state FKZ fans, fan pressure should be required to use state power, in terms of pressure and power under standard conditions, then select the fan according to the parameters you want to convert.
