What is airless disinfection?

Using dedicated airless decontamination equipment is the fastest way to provide complete coverage of disinfectant materials on surfaces to meet chemical dwell time requirements.

This article will help explain how airless disinfection sprayers work and provide a baseline for understanding how the power of airless disinfection provides the most productive way to properly disinfect and decontaminate spaces.

How does airless disinfection work?

Airless spray atomises liquid disinfectant materials into small droplets without the use of compressed air. In an airless system, with a fluid path that has been properly designed and built with materials compatible for use with chemicals found in most disinfectant materials, the liquid disinfectant is pumped under high pressure through a spray tip. The tip size and pressure is what determines the material flow rate. The tip also creates the fan pattern.

In airless spray, the fast-moving high-pressure liquid stream provides the energy necessary to overcome the fluid’s viscosity (resistance to flow) and surface tension (a force that bonds the surface of a liquid together) to form a fine spray.

In the depiction of spray from a gun, high pressure forces fluid through a small nozzle (spray tip). The fluid emerges as a solid stream (sheet) at a high speed. When the solid stream hits the air, it becomes disrupted. This disruption breaks the fluid into fragments initially, then ultimately very small droplets that form the spray pattern.

What are the benefits of airless disinfection?

Airless disinfection saves time, energy, and costs across the board by presenting a more efficient alternative to traditional cleaning techniques and cleaning solution applications. For desktops, floors, and walls that need to be spotless, airless disinfection spray cleaning is the best option. The same goes for equipment and hard-to-reach places; if a piece of equipment is heavily trafficked, airless disinfection spray cleaning can completely remove germs and dirt.

Dedicated airless disinfectant sprayers provide an easy and economical way to properly apply disinfectants and effectively disinfect, sanitize and deodorize surfaces. Professional contractors prefer to use airless sprayers to disinfect spaces for several reasons, the most popular being:

  • Speed: Airless spraying of disinfectant materials is faster than spray bottles, pump sprayers and electrostatic sprayers so more jobs are completed in less time.
  • Coverage: Airless sprayers produce an even coat of disinfectant while providing the most consistent coverage on all types of surfaces.
  • Versatility: Airless Disinfection can be used for a wide variety of decontamination jobs, including interior and exterior jobs, and can easily be transported from jobsite to jobsite.

Where can airless disinfection be used?

You can use airless disinfection cleaning methods on many surfaces and in many facility types. This cleaning technique is safe to use in offices, schools, medical facilities, commercial kitchens, and countless other spaces that require a more complete clean.

What are the benefits of continued use?

Airless disinfection kills germs, bacteria, and viruses from surfaces and lasts for a while. However, it won’t continuously prevent covered surfaces from becoming re-infected. Some institutions that see higher traffic and use, such as hospitals and schools, will benefit more from continued or regular use of airless disinfection.

Is airless disinfection safe?

Before you begin spraying, be sure you’ve read all safety and operational instructions that came with your airless disinfectant sprayer and have proper personal safety gear, such as eye protection and a respirator. Always be aware that airless sprayers can put out a lot of pressure – often enough to pierce skin. So, never point the gun at yourself or anyone else. Also, it’s important to make sure to adequately ventilate your work area before spraying.
Airless spraying is the most efficient method to apply disinfectants and sanitizers. These spraying techniques will help you improve application consistency and ultimately reduce the time you need to complete disinfecting jobs.

Is airless disinfection environmentally friendly?

Yes, airless disinfection is environmentally friendly, however this largely depends on the chemical solutions that are used to fill the disinfection tools. The airless process can be performed with many different types of disinfectants, including green cleaning products.

How quickly does airless disinfection work?

Airless disinfection begins to work immediately when sprayed and the surfaces should remain wet with applied solutions for at least two minutes to allow the appropriate dwell time. Typically, chemicals are applied while spaces are vacant.

How much time does airless disinfection take?

The amount of time required to perform airless disinfection services is highly dependent on the size of the area to be cleaned. It’s important to follow application instructions in order to allow the solutions to work effectively, and the length of time needed for application will depend on the size of the room and type of facility.

Does airless disinfection spray damage any sensitive surfaces?

Airless disinfection is safe to use around sensitive surfaces, such as wood, upholstery and electronics. Space occupants are also typically asked to store certain items prior to disinfection, such as paperwork and clothing.

Is airless disinfection more effective than other cleaning methods?

Airless disinfection reduces the amount of time it takes to completely disinfect surfaces by up to 50%, so it is an extremely effective method when compared to more traditional cleaning techniques. It is a better way to reach surfaces that are challenging to clean, gives a more even coating of chemical solutions to objects, promotes fast, cost-effective commercial cleaning, and offers many other benefits to today’s businesses. Other cleaning methods, such as fogging systems, misters, and manual sprayers take a more passive approach to applying cleaning solutions, which often leads to uneven chemical coverage. They are more likely to leave behind unwanted particles and microorganisms and take longer to manually apply.

Is airless disinfection right for my facility?

Airless disinfection is used at countless types of facilities and is most beneficial to those that see regular high traffic, contain hard-to-reach objects that need cleaning, have increased exposure to harmful microorganisms or experience or suspect an outbreak of an infectious disease.

How much do airless disinfection services cost?

The cost of airless disinfection is highly dependent on the location and size of the space to be cleaned.

How do businesses prepare for airless disinfection?

Businesses receiving airless disinfection services can prepare their space for cleaning by storing items that do not need to be sprayed, such as loose papers and articles of clothing. Having these items out in an area can impede a cleaning team’s ability to apply cleaning solutions quickly and easily, just as with other cleaning services.

  • Remove paperwork and folders, clothing, garbage, clutter, and any other items from surfaces
  • Store all food, open containers, dishware, and cutlery in a safe space away from surfaces
  • Ensure floors are free of unnecessary items (dirt will be handled by the cleaning team)
  • Take down all decorations so that walls and surfaces may be easily cleaned
