The 'Duo-Air' Invention harnesses the hydraulic power produced from the refilling cycle of a cistern and uses that energy to drive a burst of air over 2 separate fragrance blocks into the washroom environment. When the cistern is flushed air is sucked back in to the unit (once again over the blocks), where it becomes saturated with the fragrance and is then gradually pushed back in to the washroom as the cistern is refilled again. This cycle has many advantages. Firstly, the fragrance is delivered precisely, every time the toilet has been flushed, slowly (a minute or so) so the next person to enter the washroom can benefit. This is a feature that even no moderately priced electrical unit can provide. Secondly, the fragrance block is completely harmless to the environment, using only a cellulose based gel to carry its fragrance.

The device is unique to the industry in that it will take very little time to install, also, it will install in all commercial and domestic toilet cisterns as well as into the cisterns of urinals.

A huge advantage for the distributor of this product is the serviceable refill units which will need replacing monthly.

This project is currently pending manufacture and requires valid interest from a potential 50/50 partner to proceed.
