Radio-isotope 放射性同位素抽風櫃




Radio-isotope 放射性同位素抽風櫃
 

用途分析

  • 對人員進行保護,通過DIN 25466 測試
  • 如果增加對輻射防護的需求,則在操作實驗時抽氣放射性物質
  • 防止滲入、汙染和外部輻射照射
  • 排出內部產生的煙霧、氣溶膠和顆粒物質,防止有毒有害汙染物滲入到實驗室
  • 預防櫃內有害氣體濃度過高以及可能形成的爆炸性危險
  • 防止化學液體濺射傷害
  • 預防懸浮顆粒或微粒從櫃內滲出傷害
  • 依照DIN 25466標準建造的抽風櫃,通常不適用於微生物實驗
  • 不適合開放式分解反應

註解說明:

  • (1)所有排風量指標均為面窗開啟500 mm高度時(根據EN14175)測試的資料,跟蹤氣體最大值為德國標準(BG RCI )推薦的數值。
  • (2))壓力損失值是指清潔/污染的狀態。
    抽風櫃氣流閥的最大進氣壓力值不應超過600 Pa。
    標示的最低換氣率根據EN14175-3規定的測試條件而定。設計通風系統大小時,必須滿足此最低換氣率。
    若現場使用了排風監測系統或者氣流閥,排風量要求會有所不同。運行條件必須徵得Waldner同意。
    對於帶有過濾器的通風櫃,必須將集成過濾器級的壓力損失加到通風櫃的壓力損失上。
