Frequently Asked Questions

> Source: DanQ official website and the verified local product catalogue. Updated for website use on 2026-08-13. > > This FAQ focuses on practical buyer questions. Specifications, MOQ, lead time, control method, accessories and warranty coverage vary by model and order, so the final quotation and product manual shall prevail.

Please tell us the space type, approximate floor area or cubic volume, ceiling height, layout, airflow or HVAC conditions, preferred installation method, desired scent intensity, operating hours, target market, estimated quantity, and whether you need fragrance development or OEM/ODM service. Photos, floor plans and HVAC drawings can help us recommend the equipment quantity and placement more accurately.

DanQ scent solutions can be used in hotels, offices, retail stores, shopping malls, showrooms, clubs, casinos, real-estate projects, medical institutions, homes and vehicles. The appropriate solution depends on the size, layout, airflow and desired fragrance experience of each space.

Start with the cubic volume of the space rather than floor area alone. Then consider ceiling height, open doors, ventilation, HVAC airflow, noise requirements, installation restrictions and daily operating hours. A small desktop or plug-in unit may suit a room or vehicle; wall-mounted or standalone equipment may suit a defined commercial zone; HVAC-compatible equipment is usually considered for larger or multi-zone spaces.

The verified catalogue includes models with stated coverage from approximately 50 m³ to 15,000 m³. Coverage is a model reference, not a guarantee for every site. High ceilings, open entrances, partitions, strong ventilation and HVAC air changes can reduce the effective scent level. Large or irregular spaces may require several units or a site-specific HVAC solution.

Depending on the model, options include desktop, plug-in, wall-mounted, standalone, ceiling-mounted and HVAC connection. Some models support more than one installation method. Please confirm power access, mounting conditions, maintenance clearance and local HVAC requirements before installation.

Yes. Selected commercial models support HVAC connection and may include the appropriate tube and connector. The machine is normally positioned near a suitable duct or air-handling point so the existing airflow can distribute fragrance. HVAC installation should be planned according to the building layout and carried out by qualified personnel. The exact connection position, equipment quantity and settings must be confirmed for each project.

Standalone and wall-mounted machines are useful for a single lobby, corridor, office, shop, restroom or other defined zone, especially when HVAC access is unavailable or separate scent control is preferred. HVAC connection is better suited to broad, concealed or multi-zone distribution. Several independent machines may provide better zoning in complex buildings.

Many DanQ machines use two-fluid cold-air atomization. Compressed air draws fragrance oil into the atomizer and disperses it as a fine, waterless mist. The exact atomization system and operating settings depend on the model.

Most commercial cold-air models are waterless and do not use heat. Do not add water, carrier oil or another liquid unless the manual for the specific model permits it. Using an unsuitable liquid may affect diffusion performance or block the atomizer.

Use fragrance oil with a viscosity and formulation suitable for the selected atomization system. Compatibility can vary by machine and oil. If you plan to use your own oil, send the specification or a sample for evaluation before bulk use. Water-based liquids should not be used in models designed for oil-based fragrance.

DanQ states that it offers more than 3,000 scent options, including tea, floral, fruity, food, woody and branded-style notes. Selection can be based on the space, brand positioning, target market and preferred scent direction. Fragrance samples should be evaluated before a final bulk order.

DanQ states that it supports OEM/ODM service and fragrance solutions. For a custom scent, please provide the target application, desired scent character, reference fragrance if available, target market, compliance needs, packaging format and estimated volume. Feasibility, sampling process, MOQ, development time and cost must be confirmed for each project.

Adjustment methods vary by model. They may include intensity levels, work/pause cycles, operating periods, touch buttons, remote control, Bluetooth or Wi-Fi/app control. Start at a low setting, allow the fragrance to circulate, and increase gradually. Avoid over-scenting, particularly in enclosed or sensitive spaces.

Oil consumption depends on the model, atomizer, intensity setting, work/pause cycle, daily schedule, room volume, ventilation and fragrance viscosity. A single universal consumption figure would be misleading. Please provide the intended operating schedule and selected model for an estimated refill interval and operating cost.

Many DanQ machines use refillable bottles or canisters, while some models may support disposable fragrance bottles. Confirm the bottle type and capacity on the individual product specification. Turn off the device before refilling and avoid spilling oil onto painted or plastic surfaces.

Follow the manual supplied with the model. Several current commercial product pages instruct users to remove the oil canister, clean it with suitable alcohol, run the cleaning liquid through the system for about 5–10 minutes, switch off the machine, and then reinstall the canister with fragrance oil. Maintenance frequency depends on usage and oil characteristics. Disconnect power before handling internal parts, and do not improvise a cleaning liquid if the manual specifies otherwise.

First check the oil level, power supply, schedule, work/pause settings, bottle connection, air outlet and any HVAC tube. Thick or incompatible oil, residue in the atomizer, a loose seal or blocked tubing can reduce output. Clean the oil path according to the manual. If the issue remains, send the model number, serial information, photos or video and a description of the oil used to the after-sales team.

Product pages list accessories such as atomizer cores, seal rings, adaptors, keys, mounting brackets, tubes and user manuals, depending on the model. DanQ also states that some issues can be handled through remote guidance or maintenance video. Confirm spare-part availability and shipment arrangements for the selected model before ordering.

Yes. Multiple official product pages state that sample orders are accepted for evaluation and testing before bulk purchase. Samples and freight are normally charged. Availability, sample lead time and shipping cost depend on the model and destination.

MOQ is model-specific. Current official product pages show different minimums, including small quantities for selected commercial models and higher quantities for compact or consumer models. Stock trial orders may be accepted, while one current product FAQ states that OEM orders are usually 500 pieces. Please confirm the exact MOQ for the model, customization and packaging required; do not treat one product's MOQ as a company-wide rule.

Depending on the model and order quantity, customization may include logo, label, color, packaging and selected functions. Logo methods shown on current product pages include laser engraving, stickers and printing. Please provide the model, quantity, target market, artwork, color reference, packaging requirements, voltage/plug requirement and required certifications for evaluation.

Current official product FAQs request editable CDR or AI artwork. The logo position, size, color, process, sample approval, setup charge and minimum quantity must be confirmed before production.

Several current product pages display a reference lead time of 1–15 days, depending on order quantity. This is not a fixed promise for every order. Stock status, customization, sample approval, order volume, packaging and production schedule can change the actual lead time. The confirmed quotation or proforma invoice should state the final schedule.

Official product pages describe standard packaging such as a protective bag, anti-collision foam, blank box and outer carton. Customized packaging is available subject to quantity and cost. Shipping options shown include express delivery under DAP terms and air or sea transport under CIF/C&F terms. The available Incoterm, route, freight and import responsibilities should be confirmed for the destination.

Many current commercial-machine pages state a one-year limited warranty from the buyer's receipt of the machine. The stated coverage commonly includes the pump, PCB and internal wiring, while atomizers, atomizer cores, seal rings, the outer shell and damage caused by misuse are excluded. Warranty wording may vary by model and sales contract, so confirm the exact terms in writing before ordering.

Provide the model, order information, detailed fault description, photos and video for evaluation. DanQ states that some issues can be resolved through remote guidance. When a covered fault is confirmed and replacement is required, corresponding spare parts may be supplied; current product pages note that parts may be shipped with the buyer's next order. The agreed sales contract and model-specific warranty terms shall prevail.

DanQ states that its devices are certified by CE, RoHS and SGS, its fragrance oils are approved by IFEAT, and the company obtained ISO 9001 and SEDEX certification in 2018. Buyers who need compliance documentation should request current certificate copies, report numbers, validity information and model or market applicability before purchase.

Scenting should be managed responsibly. Use compliant fragrance oil, maintain ventilation, start with a low intensity and consider occupants who are sensitive to fragrance. Healthcare, childcare, food-service and other regulated or sensitive environments may require additional site assessment and local compliance checks. A scent machine creates ambient fragrance; it should not be presented as removing formaldehyde, purifying air, treating illness or replacing ventilation and professional odor remediation.
