THE COMMERCIAL TOILET OF CHOICE
Despite the vital role it plays in effective sanitation, the toilet has not fundamentally changed since the late 1800s. With UK toilets averaging 9 litres per flush and accounting for up to 70 – 85% of commercial water use in buildings it’s easy to see why traditional toilet systems have become inefficient for modern use.
Previous efforts to reduce the amount of water used for toilet flushing have had performance and convenience implications and in the main, received poor reviews from users. Recognising the need for an alternative solution which uses less water and performs better inspired the development of Propelair.
WHY IS PROPELAIR DIFFERENT?
Water flows from the cistern in to the pan under gravity, carrying the waste out in to the drain. They are dependent on a sufficient volume of water to perform the task, but the flushing mechanisms used in standard WCs often result in leaks. Water regulations require all new WCs to have a full flush of no greater than 6 litres. Some standard WCs are available with a full flush volume of under 6 litres, but as water volume reduces, so does available performance. The reduction in water can lead to double flushing.
This uses the same flushing principle as standard WCs but the cistern is provided with a reduced flush of no more than two thirds of the full flush which is intended for liquids as opposed to the full flush intended for solids. Again, the reduction in water can lead to double flushing.
Instead of flushing with water flow and gravity, waste is shredded into slurry and electrically pumped through small-bore pipes to meet the drain. This can be noisy and prone to blocking the shredder.
These systems improve performance by using the pressure of the incoming refill water to compress an air store, which acts upon the next flush to boost water flow into the pan.
Requires the building to be fitted with a central vacuum drainage system which sucks waste out of toilets during flushing for onward disposal. They require little water to flush due to the power of the vacuum, but are energy intensive and cannot connect to existing drains.
When the toilet is flushed, a trap door opens to allow the waste to drop into a second compartment, which a compressed airline is able to pressurise to force the contents through a small-bore waste pipe.
Easily retrofitted to existing drainage systems using 4inch (110mm) bore pipes
Propelair can be installed as a like-for-like replacement for conventional toilets on vented gravity drainage systems.
Alternatively, Propelair can connect onto 2inch/50mm small bore flexible pipes.
Propelair can connect to existing drains using 2 inch / 50mm flexible waste pipe, which the air flush can push the waste through without a gradient, unlike conventional toilets which rely on a fall in the plumbing network.
