All factory exhaust systems need ventilators,but for special working environment,not all fan blowers are suitable.For example,we can’t use steel fans in acid environment,just because acid will corrode the blower,and make its lifetime shorter and shorter,or even broken down.
 
Above case is a normal situation when choosing fan blowers.Many customers buy exhaust fans for chemical plant，plastic plant,electroplating plant which may have acid air all around the factory.Some of them select full stainless steel fans,and some choose fiberglass one.Certainly full SS fan is good quality and works well,but the price for this is really really expensive,here we suggest to use fiberglass ventilators.
 
For this fiberglass fan,acid environment is never a question,it can performance very well as people expect,and the size of it is from 750mm to 1460mm,so it can take the place of JS model when in special environment.And the most important point,the price is much cheaper than full SS fans.So in other words,fiberglass fan is sometimes the first choice.
