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.

How it works…

1. Propelair® has a two-section cistern; one for air and one for water

2. Before Flushing, the lid is closed to form a seal

3. When the flush sensor is activated water enters the pan to wash it, followed by air from the unique patented pump. The air cannot escape due to the sealed lid. This pushes out the entire contents of the pan to give a powerful, reliable flush.

4. The remaining water fills the water trap.

5. The flush is completed in 3 seconds with the toilet ready to be re-flushed in 20-30 seconds. (subject to water supply pressure)

Conventional Method

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.

Revolutionary Method

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.

Installation benefits to your business:

Positioning flexibility

Toilets can be installed anywhere, working within your design plans.

Saves space

Small bore pipes use significantly less space than conventional drainage systems

Eliminates drain alteration costs

If repositioning of the toilet is required.

Add toilets

Without having to extend the existing drainage system.

Save Water

Toilet flushing can account for up to 48% of water consumption in commercial buildings. Changing your toilets to a more efficient technology can really pay dividends when seeking to save water and energy.

Uses up to 84% less water

Propelair uses only 1.5 litres of water per flush, a fraction compared to the UK average of 9 litres. Average flush volumes can be significantly higher than their cistern capacity due to double flushing, leakages and filling while still flushing.

Save Money

Water is becoming an ever more valuable and costly resource. Propelair is a quick, simple and economic solution to reducing water costs instantly.

Reduce outgoing costs

Propelair reduces water and sewage bills by up to 60%.

Achieves quick payback

This can be achieved in less than one year.

Reduce Carbon

Propelair’s significant water savings help organisations to reduce their environmental impact by becoming more efficient and using less resources.

Uses up to 80% less energy

Boosts resource efficiency and building performance.

Creates on average over 80% less carbon

Less energy for water and waste processing, meaning the toilet’s carbon footprint is reduced on average by over 80%.

Improve Hygiene

Propelair is one of the most hygienic systems available, creating a cleaner toilet environment for customers, clients, patients and staff, while having a positive impact on health, well-being and productivity.

Eradicated aerosol germs

Propelair reduces aerosolised germs by up to 95%. The germs are trapped inside Propelair’s unique closable lid, and then efficiently removed with its powerful air flush, creating a more hygienic and healthier washroom environment for users.

Reduces odours

Thanks to Propelair’s unique closable lid, odours are dramatically reduced.

Protected by Polygiene BioMaster™

Antimicrobial additives in the handle help reduce germs.

Removes contaminants

Conventional toilets can leave 6% of previous users’ contaminants behind after flushing, which can become airborne during frequent flushes. Propelair removes up to 99.9% of contaminants, ensuring less risk of cross-contamination.

Avoid the “sneeze effect”

Flushing a conventional toilet creates a “sneeze effect,” spraying bacteria, viruses and moisture into the air. These airborne aerosols can travel up to 1 metre away from the toilet itself contaminating the surrounding washroom surfaces.

Harmful bacteria can survive up to 24 hours on washroom surfaces making it a perfect breeding ground for viruses and germs to spread. With Propelair, this unhygienic “sneeze effect” is avoided.

Improved Design

Propelair’s design is a significant step change compared to conventional toilets, with better performance, quicker flush and a simple maintenance process.

High performance

Combining 1.5 litres of water and displaced air technology creates a powerful, high-performance flush which easily removes all waste with one flush.

Queue time reduced

Propelair quickly refills in up to 30 seconds compared to conventional systems which can take up to 2-3 minutes. An efficient flush saves time and reduces queues, especially during periods of high usage.

Maintenance made easy

Propelair’s rimless pan and side hinges make previously hard-to-clean areas easily accessible, ensuring a thorough cleaning process can be carried out.

Durable design

Propelair is designed to be strong and durable, making it well suited for heavy use / challenging environments.

Why is Propelair different?

Standard WC

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.

Dual Flush

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.

Pressure assisted

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.

Compressed air

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.
