AmbiCube and AmbiWall reduce the risk of infection in offices, meeting rooms, canteens, ...

The AmbiCube is a compact, versatile air purifier. It is equipped with two particulate filter stages and removes 99.995 percent of all harmful particles from the air.

The AmbiWall is a versatile all-rounder: With an air volume flow of up to 1,200 cubic meters per hour, the AmbiWall reliably purifies the room air from harmful particles. Soundproofed, it can also be used excellently as a partition wall between work areas. The housing wall can be used by users for information and communication purposes, and depending on the need, screens, display cases, tool holders, or pinboards can be attached.

The AmbiTower designed for indoor use filters out particles that, despite local extraction, could escape into the hall air. At the same time, it filters out fine dust, viruses, bacteria, spores, pollen, and fungi. This not only benefits the health of employees during Corona times.

With solutions from Keller Lufttechnik, companies can now not only purify the air in production halls and manufacturing plants but also have convincing solutions for offices, meeting rooms, canteens, and halls of any size with AmbiCube, AmbiWall, and AmbiTower.

Now manufacturing plants and industrial companies can obtain all air purification devices and systems from a single source: the traditional company Keller Lufttechnik, known primarily for its extraction systems for industrial use, has expanded its Ambi product family. The flexible, compact plug-and-play devices AmbiCube and AmbiWall filter viruses, bacteria, fungi, pollen, spores, and fine dust out of indoor air at a rate of 99.995 percent, thereby protecting the health of the people working there.

The coronavirus highlights the importance of indoor air quality — rightly so. According to current findings, 90 percent of infected individuals contract the virus via airborne droplets (> 5 micrometers, mm) or aerosols (< 5 mm), which carry the virus and can remain suspended in indoor air for hours. This means: air purification devices that filter these particles from the air help significantly reduce the viral load and thus lower the risk of infection. With the AmbiCube and AmbiWall, Keller Lufttechnik from Kirchheim unter Teck near Stuttgart now offers two devices capable of doing exactly that.

New: AmbiCube for pure indoor air

The AmbiCube is a compact, versatile room air purifier. It is equipped with two levels of particle filters, an ePM1 65% according to ISO 16890 (formerly F7), and an H14 filter according to EN1822. This removes 99.995 percent of all particles from the air. This includes even the tiniest particles measuring just 0.1 to 0.3 micrometers. A first filter change is expected after two to five years, depending on usage intensity. A measuring device indicates when the time has come.

The AmbiCube cleans 1,000 cubic meters of air per hour and is suitable for rooms up to approximately 70 square meters. "If rooms are larger, unusually high, or have an unfavorable geometry, multiple devices can be easily combined," says Ulrich Stolz, Head of Technology at Keller Lufttechnik.

Solutions tailored to every room

The Institute of Fluid Mechanics and Aerodynamics at the University of the Bundeswehr Munich recommends, given the danger posed by the virus, an air exchange rate between four and eight. "This means the room air volume is filtered four to eight times per hour," explains Ulrich Stolz. "As specialists in clean air, we advise our customers professionally and determine the device or combination of devices best suited to each situation."

Every location has the right device: this is why the AmbiCube has siblings: including the large AmbiTower, designed for (production) halls, which has been part of the range for some time and is currently selling well, as well as the new AmbiWall.

New: AmbiWall filters fine dust and viruses

"The impetus for developing the AmbiWall was the fine dust problem in public spaces," reveals Ulrich Stolz. "Because outside, fine dust limits are up to 25 times lower than occupational safety limits in industrial halls. From our perspective, this created an urgent need for action. At the time, we didn't yet anticipate how quickly our new development would become relevant for indoor environments. Because, it must be known: viruses are particles comparable to fine dust. What filters out fine dust also filters out pathogens like bacteria and viruses. Currently, our AmbiWall is primarily on antiviral missions."

AmbiWall, the all-rounder

The AmbiWall, as the name suggests, has the shape of a wall. A 60-centimeter-wide base provides it with a stable stand. It draws in contaminated room air from above, filters it through two Keller Long Run (KLR) filters and an H14 filter, and releases it back into the room below the base, cleaned. The airflow rate ranges between 800 and 1,200 cubic meters per hour and is infinitely adjustable.

The AmbiWall is a versatile device: soundproofed, it can be used excellently as a partition between work areas. The housing can be used for information and communication purposes, and depending on needs, screens, display cases, tool holders, or pinboards can be attached. Like the AmbiCube, the AmbiWall stands on casters, making it easy to move if room usage changes. "The two new Ambi products are intuitive to operate and designed as plug-and-play solutions," says Ulrich Stolz.

Additional solution for production

Keller Lufttechnik has been setting "standards for pure air" for over 100 years, as the slogan states. The company's main business is extraction systems for industry. "But it’s not always possible to capture and extract airborne substances directly at the source," explains Ulrich Stolz. "The larger AmbiTower and the new AmbiWall provide complementary solutions to capture all particles that, despite local extraction, could escape into hall air. At the same time, they filter out fine dust, viruses, bacteria, spores, pollen, and fungi. This benefits health not only in times of COVID-19."

Suitable for all rooms — from large halls to small offices

With Keller Lufttechnik solutions, companies can now not only purify the air in production halls and manufacturing facilities but also have convincing options for offices, meeting rooms, canteens, and halls of all sizes with AmbiCube, AmbiWall, and AmbiTower. "This means for our customers: they get everything from a single source, have only one contact person, and benefit from our comprehensive advice and reliable service for all application areas," emphasizes Ulrich Stolz.

Important: observe hygiene rules despite air purification devices

It is important for users of air purification devices to know that, despite these systems, they should continue to observe the current COVID hygiene rules (wearing masks, maintaining distance, washing hands). While the devices clean the indoor air and reduce the overall viral load, if someone speaks, shouts, sings, etc., and releases viruses, others can come into contact with them even before the device has captured and filtered out the particles.
