systems owes its successful operation to four main details:
Urinal bowl design
The urinal bowls are hygienically designed to minimise splash back and direct any drips to the floor, rather than the pipework or wall where it is difficult to clean. The outlet is an integral factory installed spigot, which eliminates leaks.
No individual traps
Individual traps are a maintenance headache and invariably leak once dismantled for unblocking. The AirFlush system eliminates individual traps and uses a single easily cleaned trap at the drain end.
Negative pressure system
Without individual traps convection currents could cause odour problems but the AirFlush system uses a low wattage, long-life DC fan to maintain a gentle flow of air down the urinal bowls. The fan power consumption is similar to that of mains powered urinal controllers, I.E. about 3W.
Wastes are specified at 50mm minimum and installed at 1:18 minimum fall to prevent scale build up.
