We had some problems with our contact form with the security code. We found out yesterday with our web tracking that we got people clicking on the page and then leave our site without using the contact form. We believe it is because they entered the code in lower or mixed case where it required upper case. We have put a warning about the case on the contact form now and an option to email us or details to contact us otherwise.
For a bit of website hype: Type Highveld in MSN Encarta and you will find us on the page explaining what it means, sitting there with Highveld Steel and Highveld Radio, two South African icons. We got there because we ranked no 3 on page 1 of MSN Live search...

We now have access to Australian made fans from one of the major fan suppliers and we have the fan engineering expertise and experience to help our customers in selecting the right fan for the job.

To select the right fan you need to, at the least,  know the volume of air you want to move plus the pressure the fan must work at to move that air. We are not talking of little bathroom ceiling fans (you usually only need to know only the volume there), but of larger fans connected to duct systems. You also need to consider noise, safety, efficiency and other things like available space, maintenance, etc.
