Shaandhaynta noocan ah ayaa loo adeegsadaa nidaamka haydarooliga si loo sifeeyo. Shaandhayntu waxay shaandhayn kartaa wasakhda birta, nijaasta caagga ama wasakhaynta kale, oo haanta nadiif ka dhig. Shaandhayntan waxaa lagu rakibi karaa dusha sare ee daboolka ama lagu rakibi karaa tuubo. Waxay leedahay tilmaame iyo waalka-gudubka. Marka wasakhdu ku urursato walxaha shaandhada ama heerkulka nidaamku aad u hooseeyo, oo cadaadiska gelitaanka saliidda uu gaaro 0.35Mpa, tilmaamuhu wuxuu bixin doonaa calaamado muujinaya in qaybta shaandhaynta la nadiifiyo, la beddelo ama heerkulka kor loo qaado. Haddii aan wax adeeg ah la qaban oo marka cadaadisku gaaro 0.4mpa, waalka-baas ayaa furi doona. Qaybta shaandhayntu waxay ka samaysan tahay fiber galaas; sidaa daraadeed waxay leedahay saxsanaanta sifeynta sare, luminta cadaadiska bilowga ah ee hooseysa, awoodda xajinta wasakhda sare iyo wixii la mid ah. Shaandhaynta raadiyaha 0 3, 5, 10, 20> 200, ku -filterefficiency n> 99.5%, kuna habboon heerka ISO.
