Secundum ad filtration principle, in aer filter potest dividitur in filter genus, centrifugal genus, oleum balneum genus et compositis genus. Et plerumque solebat aer Filters in engine maxime includit inertia oleum balneum aer filter, charta siccum aer filter, polyurethane filter elementum aer filter et in. Inertia oil bath type air filter has gone through inertia type filter, oil bath type filter, filter type filter three filtration, the last two kinds of air filter mainly through the filter element filter type filter. Inertia oleum balneum genus aer filter habet commoda humilis attractio resistentia, potest aptet ad pulvere et harenosum opus environment, diu muneris vitae, etc, antea in variis exempla monstrabit in cars, tractor engines. Sed hoc genus aeris filter est humilis filtration efficientiam, magna pondus, princeps sumptus et inconveniens sustentacionem, et paulatim eliminated in automobile engine. Et filter elementum chartam siccum aer filter est factum ex microporous filter paper agitur ab resina. In filter paper est raro, solutam, involvit, habet quaedam mechanica vires et aqua resistentia, et habet commoda altum filtration efficientiam, simplex structuram, lux pondus, humilis sumptus, conveniente aeris filter in praesenti. Et filter elementum ex aere filter factum est a mollis, raro et spongy Polyurethane, quod habet fortis adsorption facultatem. Hoc aer filter habet commoda charta arida aer filter, sed non habet humilis mechanica vires et late in car machinas. In incommoda de novissimis duo caeli Filtra sunt breviori officii vitae et dolosus in dura environmental conditionibus.
