圧縮空気のコストとは?


一般的に、初期投資とメンテナンス費用を含め、圧縮空気のコストは1N㎥あたり3.91円です。これだけで済むなら話は簡単ですが、そうではありません。圧縮空気のコストは一律ではなく、企業ごとに異なります。  
 

多くの製造業では生産工程で圧縮空気を使用しており、エアノズルやエアブローガンでブロー作業を行っています。しかし、圧縮空気のコストを正確に把握している企業は多くありません。自社のコンプレッサーで圧縮空気を作っているため、空気に費用がかかっているという意識が薄いケースもあります。とはいえ、圧縮空気のコストには明確な答えがないため、把握が難しいのは当然です。

圧縮空気の費用は多くの要因に左右されるため、単純にいくらとは言えません。正確に算出するには電力契約、メンテナンス費用、コンプレッサーの性能、廃熱回収の有無を考慮する必要があります。

当社ではエアブローのコストや削減効果を計算する際に、1N㎥あたり3.91円を基準値として使用しています。
この数値は特定条件に基づくものですが、比較・試算の際にはひとつの基準として使用できます。ただし、お客様の圧縮空気の正確なコストを知るには、お客様の現場条件に基づいた個別計算が必要です。
