Glued seams replace sewn seams on the filters, providing better seal integrity and preventing dust leakage. The cloth filters now have more surface area, improving dust collection and increasing overall efficiency.
2. Increased Durability: The redesigned models are built with more robust components, including stronger frames and enhanced motor protection, to withstand tougher working conditions and prolong the life of the equipment.
3. Better Mobility: Nilfisk has focused on improving the portability of their dust extractors, with lighter but robust frame, ergonomic handles, and larger wheels for optimized weight distribution for easier transportation across job sites.
4. Higher Efficiency: The updated models offer improved suction power and airflow, making them more efficient at capturing dust at the source and reducing cleaning time. Larger versions also come equipped with onboard air purge systems that help maintain filter efficiency by preventing clogging.
5. Enhanced User Interface: New models feature user-friendly controls, making operation simpler and more intuitive. The addition of features like integrated storage for accessories and clearer displays enhances convenience during use.
6. Quieter Operation: Efforts have been made to reduce noise levels, making the dust extractors quieter during operation, which is beneficial for both the user and the work environment.

These changes aim to provide enhanced performance, better user experience, and a safer, cleaner work environment.

2. How does Nilfisk’s Longopac Continuous Disposal System ensure a safer and cleaner process with demanding industrial applications like factory floors or in the construction market?

Nilfisk’s Longopac Continuous Disposal System ensures a safer and cleaner process in demanding industrial applications, such as factory floors or the construction market, through several key features:

1. Dust-Free Disposal: The Longopac system captures dust directly into a continuous, sealed plastic bag, reducing exposure to airborne particles and minimizing the risk of contamination. This makes it particularly beneficial for environments with hazardous dust, like construction sites or factories where materials such as silica are present.
2. Clean, Efficient Collection: The system features a unique, continuous bag design that allows for easy disposal without interrupting the workflow. When one section of the bag is full, it can be tied off and replaced while the extractor continues to operate, ensuring a consistent collection of dust without the need for frequent stops.
3. Reduced Cross-Contamination: The sealed design of the Longopac system prevents dust from escaping, helping to maintain a cleaner work environment. This reduces the risk of cross-contamination, especially in industries where cleanliness and safety are critical.
4. Cost-Effective and Sustainable: The Longopac system reduces the need for traditional dust bag replacements, lowering operational costs and waste. The continuous disposal bags are durable and can be reused for multiple applications, providing long-term sustainability for industrial operations.
5. User-Friendly Operation: The Longopac system is easy to use and maintain. Its simple, hands-free disposal method ensures workers can safely and efficiently manage dust removal without needing to manually handle hazardous materials.

By providing a sealed, continuous method of dust disposal, Nilfisk’s Longopac system enhances safety, reduces downtime, and helps maintain a cleaner, more organized workspace in high-demand industrial and construction environments.

3. How does the cyclonic pre-separator machine help with the efficiency and longevity of the vacuum?

The cyclonic pre-separator machine significantly enhances the efficiency and longevity of a vacuum by acting as a first stage in the dust collection process. Here’s how it works:

1. Increased Efficiency:
   The pre-separator uses centrifugal force to spin dust and debris at high speeds, separating larger particles before they reach the vacuum filter. This process reduces the amount of heavy debris entering the vacuum, helping to maintain consistent suction power and prevent clogging of the primary filter.
2. Prolonged Filter Life:
   The pre-separator does most of the work in front of the vacuum by collecting the majority of the dust and debris, preventing them from reaching the vacuum filters. This protects the filters and significantly extends their lifespan, reducing the frequency of filter cleaning or replacement.
3. Reduced Maintenance Costs:
   By minimizing the amount of debris that enters the vacuum’s filter system, the pre-separator reduces wear and tear on the vacuum. This leads to lower maintenance and operational costs, as well as fewer interruptions for filter cleaning or replacement.
4. Consistent Suction Power:
   The pre-separator ensures that only fine dust particles enter the vacuum’s filter, helping to maintain its suction power over longer periods of time. This results in improved overall performance and efficiency, especially in demanding industrial or construction environments.

By taking the majority of the collected contents upfront, the cyclonic pre-separator not only helps maintain optimal suction power but also protects the vacuum filters, ensuring both longer operational life for the vacuum and greater efficiency in dust collection.

4. Nilfisk has two single-phase dust extractors. Which features should companies consider when selecting the right single-phase dust extractor for their needs?

When selecting the right single-phase dust extractor from Nilfisk, companies should consider the following key features to ensure they choose the best fit for their needs:

1. Suction Power and Airflow:
   The primary function of a dust extractor is to maintain strong suction for effective dust collection. Companies should assess the vacuum’s suction power (measured in air watts or CFM) to ensure it’s sufficient for the type of work being performed, whether it’s light-duty tasks or heavy-duty applications. The manufacturer of the grinder, scarifier, or shot blaster will usually have a recommended CFM requirement for the vacuum to be used, and the end user can select the corresponding vacuum that best meets this requirement.
2. Filtration System:
   For environments with hazardous or fine dust (e.g., silica or concrete dust), the quality of the filtration system is crucial. Nilfisk’s dust extractors come with different filter types, such as HEPA filters, which capture ultra-fine particles and ensure cleaner air. Companies should select a model with an appropriate filter to meet safety standards and enhance air quality.
3. Tank Capacity:
   The size of the dust extractor’s tank will determine how often it needs to be emptied. A larger tank is ideal for extended use and more demanding tasks, while a smaller tank may be sufficient for lighter or intermittent cleaning.
4. Portability and Mobility:
   If the dust extractor will be used in various locations, its weight, size, and maneuverability are essential. Look for features like large, durable wheels and ergonomic handles for easy transport across job sites.
5. Noise Level:
   In work environments where noise is a concern, consider the dust extractor’s noise level. Nilfisk models are designed to operate quietly, which can help improve comfort and compliance with workplace regulations.
6. Ease of Use and Maintenance:
   Features like easy-to-access filter systems, tool-free maintenance, and user-friendly controls can significantly reduce downtime and increase the efficiency of your operations. The Longopac® continuous disposal system is also worth considering, as it allows for dust-free, hands-free disposal of collected debris, reducing exposure and improving cleanliness.
7. Compatibility with Tools:
   For a dust extractor to work effectively, it should be compatible with the power tools being used. Check for compatibility with grinders, sanders, and other surface preparation tools to ensure seamless integration.
8. Safety and Compliance:
   Depending on the industry, compliance with safety standards (such as OSHA regulations for silica dust) may be required. Ensure the dust extractor meets relevant local or national safety standards and offers features like anti-static hoses and explosion-proof motors if required.
9. Filter Cleaning System:
   Some Nilfisk dust extractors come with a filter cleaning system (such as automatic filter cleaning or manual blow-back systems) to keep the filter in peak condition, reducing maintenance and prolonging filter life.

By carefully evaluating these features, companies can select the right single-phase dust extractor to meet their specific application needs, improve worksite safety, and maximize operational efficiency.

5. What kinds of facilities are choosing Nilfisk’s cordless dust extractor for their surface preparation needs, and why?
