NOTIFICATION METHOD OF USE LIFE OF FILTER MEMBER

To provide a connection device for issuing a notification alarm of a use exchange of a filter member.SOLUTION: In a notification method of a use life of a filter member, at least one filter member for filtering an air contamination source is provided, the air contamination source is detected in at least one ventilation path after filtration by at least the one filter member, at least one gas detection device for outputting detection data of the air contamination source to the outside is provided, the detection data of the air contamination source detected by the gas detection device are received, a calculation comparison is performed to the detection data, and at least one connection device for displaying a deceleration speed after the filtration of the air contamination source by at least the one filter member is provided. When the deceleration speed after the filtration by the filter member which is calculated by at least the one connection device reaches a preset alarm value, at least the one connection device issues a notification alarm for a use exchange of at least the one filter member.SELECTED DRAWING: Figure 1 【課題】濾過部材の使用更換の通知警告を発出する接続装置を提供する。【解決手段】空気汚染源を濾過する少なくとも１つの濾過部材を提供し、少なくとも１つの前記濾過部材による濾過後の少なくとも１つの通気経路において前記空気汚染源を検出し、前記空気汚染源の検出データを外部に出力する少なくとも１つの気体検出装置を提供し、前記気体検出装置により検出された前記空気汚染源の検出データを受信し、検出データに対して演算比較を実施し、少なくとも１つの前記濾過部材による前記空気汚染源の濾過後の低下速度を表示する少なくとも１つの接続装置を提供し、少なくとも１つの前記接続装置により計算される前記濾過部材による濾過後の前記低下速度が予め設定される警告値に達した場合、少なくとも１つの前記接続装置は、少なくとも１つの前記濾過部材の使用更換の通知警告を発出することを特徴とする濾過部材の使用寿命の通知方法である。【選択図】図１
