Maintaining hygienic, odour-free washrooms requires more than periodic manual cleaning. In busy commercial environments, bacteria, uric acid build-up, staining, and unpleasant odours can return quickly between service visits.
Automatic dosing dispensers provide a continuous solution — delivering controlled amounts of cleaning and deodorising fluid directly into the WC or urinal system with every flush.
At Unicorn Hygienics, we offer three specialist dosing systems designed to suit different environments, installation requirements, and budgets:
Here’s how they compare.
OdourClean is the simplest and most economical system in the range. Using a gravity-fed drip mechanism, it continuously doses cleaning fluid into the cistern or pipework without requiring batteries, pumps, or motors.
Its uncomplicated design makes it highly reliable while keeping both installation and ongoing servicing costs low.
Unlike cartridge-based systems, OdourClean uses bulk 25L liquid refills, making it particularly cost-effective for facilities managing ongoing consumable costs.
OdourClean is best suited for smaller sites, standard washroom layouts, or facilities looking for dependable washroom hygiene at the lowest operational cost.
Puresan is designed for environments where gravity-fed systems are difficult or impossible to install.
Its integrated pump-operated system allows installation above or up to 0.5m below the cistern, giving facilities teams far greater flexibility during installation.
The system uses a 310ml cartridge refill and offers programmable 30 or 60-day dosing intervals for predictable maintenance scheduling.
Puresan also includes several installer-focused features, including a built-in spirit level, tamper-resistant housing, concealed wiring, and battery/refill warning LEDs.
Puresan is ideal for difficult installations where access, height, or pipework positioning prevents the use of standard gravity-fed systems.
Sanair is the highest-capacity and highest-coverage system in the range.
Its dual-action design combines liquid dosing with integrated ambient air freshening. While the system continuously delivers cleaning fluid into the WC or urinal, a built-in wick diffuser simultaneously releases fragrance into the washroom air.
Designed for busy commercial environments, Sanair can also serve multiple fixtures from a single unit, improving efficiency while reducing servicing demands.
The system uses a larger 610ml cartridge capable of delivering over 6,000 metered doses.
Sanair is purpose-built for larger, high-traffic washrooms where hygiene, fragrance control, and servicing efficiency are priorities.
