oxygen separation unit 3d model

i wish to develop one experimental setup (oxygen separation unit). this unit contains portable air compressor at start which supplies atmospheric air and air enters flow meter where i can regulate the inlet air flow and pressure , then it enters the humidity remover because i wish to remove the humidity from air due to the good futher processing and then the dehumidified air enters the one way valve . these all connected using blue cable like wire which has diameter dimension in the range of 1-2cm. then the air enters the long tube i.e dimension are inner diameter of the tube is 12 cm and outer diameter of the tube is 13 cm which is divided into two halves. the air enters bottom halve of the tube. especially in the division area i have to keep my membrane sample which is going to separate the oxygen from air . the air enters membrane and oxygen alone separated by the membrane and the separated oxygen species come out of the top halve of the tube . the separated oxygen is collected using canister via cable t
