Scent Diffusers

Aurascent is a leading provider of premium scent delivery systems, offering a diverse range of scent diffusers from HVAC, to portable, to battery operated scent diffusers.  Whether you require fragrance diffusion in a vast hotel lobby or a compact room, we have the right diffusers and machines to effectively & efficiently scent your environment.

While traditional methods such as burners, candles, reed diffusers, sprays, and refreshers are commonly used to disperse scents, our advanced cold air diffusion technology offers distinct health and safety advantages.  Unlike these conventional methods, our cold air diffusion technology ensures the preservation of fragrance aroma oils, providing a consistent and long lasting scent experience. Our systems are built on proven technology that surpasses the effectiveness of current market solutions.



Cold air diffusers are specialized devices that distribute scents using cold air diffusion, a process that involves pressurizing cold air to break down aroma and essential oils into an ultra-fine dry mist for dispersion.

Aurascent aroma oils are dispersed in a dry mist of microscopic particles, typically smaller than 1.0 micron, offering a more refined and efficient scenting experience.  To put this into perspective, a perfume spray produces 50x larger particles at around 50 microns.

Dispersing fragrance through a centralized heating, cooling, HVAC system has become increasingly streamlined.

Aurascent's fragrance oil is diffused into a fine mist of minuscule particles via the pressure of purified cold air, a process known as cold air diffusion.  This mist is then emitted into the HVAC ducts, ensuring a uniform scent distribution throughout the designated spaces.

We can install our HVAC scent diffusers through your AHU (Air handling units) or FCU (Fan coil units).
