Shaandhooyinka shidaalka iyo filtarrada saliidda (miirayayaasha saliidda mishiinka) waa laba qaybood oo baabuur oo kala duwan oo leh adeegsiyaal hoose oo kala duwan. Shaandhooyinka shiidaalka ayaa ugu horrayn ka sifeeya wasakhda shidaalka si loo hubiyo nadaafadda shidaalka, iyadoo saxnaanta shaandhaynta caadiga ah ee u dhaxaysa 1μm iyo 50μm, hagaajinaysa waxqabadka injiinka iyo dhaqaalaha shidaalka. Saliidda saliidda, dhinaca kale, waxay diiradda saaraan shaandhaynta saliidda mishiinka, ka saarista qashinka birta ah iyo wasakhooyinka kale, ilaalinta qaybaha matoorka gudaha. Alaabooyinka qaarkood, filtarrada shidaalka iyo saliidda ayaa laga yaabaa inay lahaadaan goobo lagu rakibo iyo qaab-dhismeedyo kala duwan taas oo ku xidhan nooca baabuurka iyo nashqada injiinka.
