Airdri is a British manufacturer of hand dryers based in Oxford. Their hand dryers can be found branded as Airdri, Bobrick, Redring, and Cannon. The model number system for airdris is so bad I won't include them
The quarto/classic is a traditional hand dryer that was recently discontinued, it features a flap that you can push to dry your face. Touch button units are rare
This is almost identical to the Quarto with the only difference being a high speed nozzle in place of the flap. Unlike the Quarto, these are still being made
These dryers are similar. The Quazar is a low energy traditional hand dryer and the Quest is as basic as high speeds get.
This is a DDA compliant traditional hand dryer, I am not sure why it's still made
Economy dryers that come in either Steel or ABS, these are discontinued. I have no idea who thought it would be a good idea to put these in a posh shopping centre.
This is a rare hand dryer with a weird futuristic shape, despite this, it's pretty much the same as the Quarto. This is discontinued.
[Insert bad airdri model number system]
These are extremely rare DDA compliant versions of the Quarto.
These are similar to the Quote but have a more interesting shape
This hand dryer appears on old airdri promotional stuff
