Create an attractive Trade show Booth for Advanced Air Purifier

SAGE Industrial Corporation

We manufacture, install, and service Advanced Surface & Air Purification systems. Product name AirROS. Our purifiers clean the air and treat the surfaces by killing bacteria, virus', mold, odor etc... We sell these in the industrial market to customers who have perishable products like : Fresh Fruit and Vegetables, Nuts, Meat, wine, & plants.

This contest is for a booth back panel. Attached is the template.

We need a design that would show that AirROS protects the customers products by killing mold, bacteria, botrytis, e-coli, samonella, odors, etc... and works 24hr/day 7days/week to defend against re-contamination etc...
The show we need designed first is for the Farm industry and would depict the commodities listed above (6 pics).
We are definitely open to suggestions as we are not good at this.

Our only idea was a shield with the logo showing our three word idea : Destroy, Purify, Defend.
(I attached a sketch but feel free to come up with different ideas than what is on the sketch)
Our idea for a catch phrase at the top of the booth: Advanced Surface and Air Protection
AFTER this contest we will need 1-to-1 project to design a podium, and potentially banners.

I would like it simple but bright.
Again we are not good at this so please suggest what you think is best.
