    Product Details

    Product Information

    This scent diffuser is a very capable mid-area performer. HVAC30 is ideal for large homes, office buildings and open spaces up to 3,000 sq. ft. The unit can operate either as a standalone or HVAC-type connection. The powerful pump makes this model a versatile player in the residential and commercial space.

    Coverage and application:

    This is a waterless type aroma diffuser for medium and large spaces up to 3,000 sq. ft. Typical commercial applications are retail stores, pet grooming salons, large office spaces, etc.

    The model has been tested in various commercial applications including hotel lobbies, high-traffic retail stores and beauty salons. This model works equally well as a standalone and HVAC type setup.

    Fully programmable 24/7, four different programs per day with custom level intensity settings down to minutes and seconds. Waterless diffusers (also known as cold air technology) transform essential oil into nano-particles without any heating which preserves the integrity of the scent. Unlike aerosols, there is no residue or messy canisters.

    Scent cost savings:

    This is the latest technology in scenting and the total cost of ownership is less compared to burning candles or using multiple aerosols. The initial investment in this unit typically is offset by the cost-effective technology within months, not to mention the difference in the quality of scents.

    Connecting to the HVAC

    Experience outstanding fragrance scent delivered through your central heating and cooling system. Each HVAC scent diffuser comes with a metal push-in fitting that screws into the machine and a plastic tube that connects the diffuser to the HVAC air duct.

    Step 1

    In order for the aroma mist to carry through the air duct, the AC must be operating or the blower fan must be turned on. If the AC (or fan) is off, the aroma mist will stay in the air duct and won’t reach the intended space. If the diffuser is operating for a prolonged period of time with the AC fan being off there will be unwanted scent buildup in air ducts and could cause diffuser or air handler damage.

    Step 2

    HVAC setup typically requires intensity levels 10% to 15% higher compared to standalone diffuser setup. Air duct passage creates an additional volume of space through which the aroma must travel and some capacity is lost due to the extended volume of space. With a standalone setup, the aroma covers a smaller volume of space and has a slower transit time.

    Step 3

    Installing the air diffuser requires adequate space to accommodate your aroma diffuser and must be close to the air ducts. The ideal placement of the diffuser tube opening is after the air handler and before the first air register (please refer to the diagram above). Please ensure the air duct opening is further away from the air handler body to prevent possible interference.

    Step 4

    The plastic tube that connects the diffuser with the air duct should be kept as short as possible and at the near-vertical pitch. Avoid ‘sagging’ formations in the tube as this could cause oil accumulation in the lower part of the tube and possibly damage your diffuser.

    Step 5

    The diffuser plastic tube entering the air duct should be approximately three to four inches inside the duct and pitched at about 10% downward angle just to ease the aroma flow.

    Step 6

    Ensure proper insulation of the opening by using aluminum tape and secure the plastic tube to one of the hard areas to minimize any tube movement.

    Step 7

    The placement of the diffuser should be in a dry, clean, moist free environment
    nearby a proper 110V power outlet.

    HVAC30 Oil Change

    People often ask us "How long will my bottle of oil last?"

    Fragrance oil consumption varies based on diffuser model, intensity level, and usage. As a guideline, at medium intensity, operating seven days a week from 8:00AM to 8:00PM, consumption per month is roughly: HVAC10: 200ml, HVAC30: 500ml, HVAC150: 1000ml. Actual usage may differ based on settings. Read more FAQs here.
