Key features

Fan: The unique feature of the AIRFLUSH® system is the low-watt on-line fan in the vent pipe. This runs constantly, causing just sufficient air flow at the bowls to remove all odour. The fan uses a very small amount of electricity – about 3W. It is expected to last more than three years. Replacement is simple and inexpensive.

Bowl: The Ifö urinal bowls are hygienically designed to minimise splashback and direct any drips to the floor rather than the pipework or wall, where it is more difficult to clean. There is no trap under the urinal bowl, so that urine drains away quickly and potentially leaky joints and seals are minimised.

Waste: The branch discharge pipe is installed to a gradient of 1: 18. This allows rapid run-off of the urine. The system has just one running trap. To prevent build-up of sludge this should be flushed out once a week with a litre of water poured down a bowl. If a wash hand basin can discharge to the branch, this will keep the trap flushed.

Vent: Although an existing soil pipe can be used for drainage, the AIRFLUSH® must have a dedicated vent. The terminal, which has an anti-downdraught cowl, should be at least 900mm above any openable point on the building which is within 3 metres.


How it works

The AIRFLUSH® system owes its successful operation to four main details:

Urinal bowl design

The Ifö urinal bowls are hygienically designed to minimise splash back and direct any drips to the floor rather than the pipe-work 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.

Waste pipes

Wastes are specified at 50mm minimum and installed at 1:18 minimum fall to prevent scale build up.
