Some professional graphics for a new technology

Information for the business: We sell new building testing technologies
Industry: Technology
Design details: We have a new technology to bring to market and need some illustrations to put on our marketing materials. Our branding guidelines are attached, as well as examples of what kind of thing we're looking for.

Our main need is a graphic showing our technology at work within a house. The technology is effectively a "black box" which sits in a house and causes air to leak from the house, testing how airtight it is, so we'd be looking for arrows showing air flow etc, like the examples.

We are also looking for a diagram showing the components of our technology, an example (which is terrible) is enclosed. Images of our technology will be disclosed when the bid is confirmed.
Target audience: Building Industry
Ideas for the visual style: Communicative rather than artistic.
Things to avoid: Cartoon style, overly textured images
Preferred colors: See branding guidelines
Urls to draw inspiration from: Our current website: www.pulseairtest.com
Where the design will be used: Print and web
Extra notes: We need the images within 5 working days
