FFU is short for fan filter unit.it is a kind of air supply device which has motive power and filtering function.air is brought in top of FFU as passing through Hepa filters.filtered air comes out of outlet evenly,modules connection running.
FFU provides clean air and particle controlling.FFU is installed on ceiling of clean room(25% to 100% cover rate),general dimension is 2'*2'or 2'*4' or 4'*4' or the other custom size per our customer request
Features
