A double sides hand dryer dries both sides of the hands as the user moves them through or between two air outlets, depending on the model design. For commercial restroom buyers, it can be a suitable option when fast hand drying, a compact installation footprint, and frequent use are priorities. The right choice depends on more than the “double-sided” label: compare the dryer’s installation format, electrical requirements, drying method, noise, maintenance needs, and fit with your restroom layout. I recommend confirming these details against the specific model and project conditions before requesting a quotation.

This guide is for facility managers, contractors, distributors, purchasing teams, and project specifiers sourcing hand dryers for commercial restrooms. It is particularly relevant when you are comparing a double sides hand dryer with a conventional wall-mounted unit or planning multiple installations across a building. Use it to create a clear specification, assess suppliers, and reduce the risk of selecting equipment that does not suit the site. Final decisions should be based on the manufacturer’s documentation and any requirements that apply to your project.
A double-sided dryer directs air toward both sides of the hands to support drying as users insert, position, or move their hands within the drying area. Designs vary: some use opposing outlets in an open hand-drying zone, while others use a vertical, slot-style chamber. These formats differ in how users interact with the unit and how much space is needed around it. Check product drawings and instructions rather than assuming all products described as double-sided have the same configuration.
Depending on the design, a unit may use a sensor to activate airflow when hands are detected. Buyers should verify the activation method, operating instructions, and whether settings can be adjusted. Do not assume that a particular dryer is touch-free, adjustable, or suitable for every accessibility requirement without checking its technical information. The intended user experience should be reviewed alongside the installation plan.
Consider whether an open-format or enclosed hand-drying area better suits the restroom’s circulation and user needs. A more enclosed design may guide hand placement, while an open design may feel less restrictive; the actual experience depends on the unit’s dimensions and outlet arrangement. For the exterior, compare materials and finishes offered by the supplier, such as stainless steel or coated metal where available. Ask for care instructions and confirm how the finish is expected to withstand the cleaning products used at your facility.
Review the rated voltage and frequency, power consumption, airflow information, noise level, dimensions, weight, activation method, and recommended mounting conditions. Ask how the manufacturer defines any stated drying-time figure, since test methods and user behavior can affect comparisons. Check whether the electrical connection and mounting arrangement match the building’s provision, and whether service access is possible after installation. A product data sheet, installation drawing, and user or maintenance instructions are useful documents to request before ordering.
Use numerical targets as project-specific screening criteria, not as universal performance standards. For example, a purchasing brief might ask suppliers to quote against a 220–240 V AC supply, a maximum rated input of 1,500 W, and a noise target below 75 dB(A). These are illustrative requirements only, not claims about every dryer or Modun product; confirm the correct values with your electrical contractor, project specification, and shortlisted manufacturers.
Start with the restroom’s expected traffic, available wall or counter space, user profile, cleaning routine, and operating hours. A busy venue may prioritize quick user turnover and straightforward maintenance, while a quieter office may place greater emphasis on sound levels and appearance. In schools, healthcare settings, transport facilities, or other specialist environments, confirm any applicable project rules and operational requirements with the responsible professional. A dryer’s suitability cannot be determined by traffic level alone.
Measure the installation area and review the path users take from the washbasin to the dryer and toward the exit. Confirm that the unit will not obstruct doors, accessible routes, fixtures, or cleaning access. For a multi-unit project, consider whether the layout supports orderly use at peak periods and whether the chosen mounting height and location are appropriate for the intended users. Use the manufacturer’s installation dimensions and the project drawings to validate the plan.
Modun supply professional and honest service.
When comparing performance claims, ask whether figures come from a defined test method and whether they represent a typical setting, a maximum, or a different operating condition. Request a sample or demonstration when it is commercially practical, particularly if noise, user positioning, or finish is central to the decision. For larger projects, confirm the final model and finish in writing before releasing the purchase order. This creates a clearer basis for checking delivered goods against the approved specification.
The total purchase cost can include more than the unit price. Ask whether the quote includes packaging, accessories, customization, shipping terms, and any required spare parts, and compare those items consistently across suppliers. Minimum order quantities and production lead times can vary by model, finish, order size, and customization request. Request a current quotation with the proposed delivery schedule rather than relying on general estimates.
For phased or multi-site projects, confirm whether the supplier can maintain consistent model and finish availability for later orders. Clarify how changes to quantity, packaging, or technical requirements may affect price and delivery timing. If you need a sample, ask whether its cost and shipping are included or credited against a later order. These questions help purchasing teams identify sourcing risks before a project schedule is committed.
As a B2B supplier, we at Modun recommend evaluating the complete offer rather than choosing solely on a product name or headline performance figure. Share your installation conditions, target quantities, preferred finish, and project schedule so we can discuss an appropriate hand-dryer solution and clarify which information is available for the models under consideration. Confirm all technical and commercial details in the formal quotation before placing an order.
One common mistake is treating “double sides” as a standard design specification. The term alone does not establish dimensions, drying performance, sound level, controls, or installation requirements. Another is comparing quoted prices without checking whether products have the same configuration, materials, accessories, and warranty terms. Buyers should also avoid assuming a dryer will fit simply because a wall area appears available; electrical access and user circulation matter too.
It is also risky to make decisions based on a single performance claim without checking how it was measured. Ask suppliers to explain unclear figures and identify what is included in the specification. If a project has accessibility, hygiene, or regulatory requirements, verify them with the relevant project professional and product documentation. A documented review is more dependable than relying on generic descriptions.
A double sides hand dryer may be a good fit for a commercial restroom when its drying format, footprint, electrical needs, maintenance requirements, and user experience align with the site. No single specification guarantees suitability, so compare the exact models using consistent criteria and verify claims with current supplier documents. Pay particular attention to layout, installation conditions, and the total commercial terms, including MOQ and lead time. These checks help turn a broad product search into a practical procurement decision.
Before requesting quotes, prepare the project location, quantity, installation dimensions, power requirements, desired finish, and target delivery schedule. Then ask shortlisted suppliers for model-specific documentation and a written quotation that identifies included services and terms. Contact Modun with these details to discuss options for your commercial restroom project and clarify the next steps for product evaluation and sourcing.
