adjascents Smart HVAC Scent Diffuser – Black, 2L Canister

Bring professional whole-space scenting into your home or business with a powerful diffuser made for large environments. Its 2-liter oil canister, programmable controls and HVAC connection make it ideal for creating a consistent fragrance experience without constantly refilling smaller machines.

Cold-Air Diffusion Technology

This diffuser uses advanced cold-air atomization to transform fragrance oil into an ultrafine, dry mist. The fragrance remains suspended in the air longer for more even distribution, without using water or heat.

Because the oil is not diluted or heated, its original fragrance profile is maintained. The dry diffusion process is also designed to minimize residue when the machine is installed and maintained correctly.

Five Programmable Working Periods

Program up to five separate working periods based on your preferred days and times. Each period can have its own:

This gives you precise control over when the machine scents and how frequently the fragrance is released.

Wi-Fi and Bluetooth App Control

Connect the diffuser to the Scent Tech app through Wi-Fi or Bluetooth. From the app, you can connect and manage the machine, adjust its operating schedule and control its fragrance output.

The built-in digital display and control panel also allow you to operate and program the machine directly without relying entirely on your phone.

Intelligent Oil-Level Indicator

The color-changing light on the front of the diffuser helps you monitor the amount of oil remaining inside the canister:

After refilling the canister, update or reset the oil volume and level settings so the indicator can display the correct reading.

HVAC Connection

Connect the diffuser to compatible HVAC ductwork to distribute fragrance through the existing airflow. This provides more balanced scent coverage across multiple rooms or larger connected spaces.

The machine can also be wall-mounted using the mounting plate and keyhole slots on the back.
