Unverified20㎡以上开放空间促进空气流通降温，风量需≥1000m³/h、送风距离≥10m才有效；小于15㎡的宠物房选600-800m³/h即可，风量过大反而吹乱宠物毛发引起不适87% similarUnverified风速≥50m/s（风量≥50000rpm级无刷电机）适合金毛、萨摩耶等大型长毛犬，可在15分钟内吹干；小型短毛犬30m/s风速足够77% similarUnverified适用面积按换气量计算：新风量(m³/h) ≥ 房间面积(㎡)×层高(m)×换气次数(0.7-1次/h)，例如80㎡层高2.8m需要至少157m³/h新风量，选购时应选标称风量的1.3倍以留余量74% similarUnverified风速档位越细分越好：宠物场景建议选≥8档或无级调速，可精确调到微风档保证空气流通又不直吹伤宠；仅3档的机型最低档往往仍过强74% similarUnverified落地扇覆盖15㎡以上房间建议风量≥50m³/min，塔扇因出风口窄覆盖范围通常小于同价位落地扇69% similar
