Air assist pump inside laser enclosure? New baffle plate to reduce noise Better Air flow rate

Install a laser air assist pump inside a smoky enclosure. I had to design a new baffle plate to keep the noise down and to allow the fresh air inlet to be extended outside. Why? As i have space inside my enclosure and table top space is at a premium.
