The air stays clean: Odour and smoke control with Airwalls

Odours can become a problem for companies: When a well-known retail chain was looking for a solution to keep the intense smell of the fish counter away from the rest of the store, we developed the first Airwall specifically for this application. Today, this technology benefits numerous companies that want to keep unpleasant odours, dangerous gases or disturbing dust away from production halls or sales areas. Smoke can also be specifically stopped with our airwalls, so that escape routes remain safe in an emergency.

When odours must be prevented

Companies must keep the air clean. Limit values for fine dust or gases are specified to protect employees, visitors, customers and the environment. Depending on the business, however, these pollutants or foul odours are a by-product that cannot be avoided.

Waste disposal companies, for example, cannot prevent the materials to be recycled from being an odour nuisance for employees and, depending on the type of waste, an environmental hazard. The legal requirements for this are complex, as the upstream airlock must have automated rolling doors and elaborate ventilation systems. But there is a better solution.

Simpler, cheaper and more environmentally friendly, on the other hand: LWT airwalls. The effectiveness of our technologies is verified by expert opinions.

Airwalls protect against odour, dust and smoke

Airwalls reliably separate layers of air, so they can meet the requirements of the Federal Immission Control Ordinance (BImSchV). They are more efficient and environmentally friendly than air curtains. Waste management companies can therefore reduce operating costs with LWT airwalls, while at the same time improving the working environment for employees. The air barriers also seal off passages where, for example, trucks are parked that are being unloaded. Airwalls also protect against fine dust, i.e. air particles smaller than ten micrometres, as well as smoke, which can improve the long-term health of employees.

FAQ

What is an airwall and how does it work?

Airwalls are systems that accelerate air to high speeds with the help of fans and compress it into a thin jet via a patented nozzle (pressure linear module). The generated air jet prevents layers of air from mixing. Our units can be mounted on the side of gates or above doors. The air jet then separates the air over the entire height. This keeps cold air outside in winter, for example, and does not cool the air indoors. Airwalls are modular and therefore have a lot of planning freedom. They can therefore also be retrofitted without any problems.
