Questions and answers

FAQs

We have collected the most frequently asked questions so that you can get answers immediately, without waiting or additional correspondence.
Proper ventilation benefits all kinds of industries. Each has specific requirements depending on the type of pollutant and the layout of the facility.
An efficient system keeps the indoor air free of visible dust, unpleasant odors, excessive heat and moisture.
Yes, sometimes simple improvements such as the addition of exhaust fans, the improvement of duct layout, or the installation of smart management systems can make a significant difference without completely reconstructing the system.

Symptoms include retention of odors, visible condensation, overheating, stuffy air, an increased number of absences due to respiratory problems, and poor air quality test results.

The choice of the appropriate type of ventilation depends on the size and layout of the facility, but also on the type of pollutant. Even if you are aware of the importance of air quality and cleanliness, it is advisable to leave the choice of the most efficient and cost-effective solution for removing pollutants to experts.

Proper selection and design of the Air Treatment Unit is the basis of its proper operation and performance of the task. Regular maintenance of the ventilation system and inspections, removal of pollutants, mechanical maintenance of components of the air exchange system, checking of leaks and proper air flows — all contribute to optimal functioning.

The monitoring and automation of the air purification system also helps to keep everything in perfect condition.

The improvement of industrial ventilation improves performance, increases energy efficiency and enables optimal system operation. You can consider using modern filtration systems, more efficient fans and sensors to monitor air quality. Heat recovery systems significantly reduce energy consumption and bring great savings.

In a typical industrial installation, numerous vibrations and oscillations are present created by the ventilation equipment — the operation of fans, Air Treatment Units or refrigeration units. A well-installed channel network should have built-in components that prevent or significantly reduce the transmission of those vibrations. Also, it is useful to familiarize yourself with air flow control systems.

Bringing in fresh air and removing the same amount of polluted air is the basic task of the ventilation system. To achieve this, regulation flaps or airflow regulators are used. Their role is to maintain the desired flow in individual branches of the channel system regardless of changes in pressure within the channel. Depending on the type of ventilation system, modern air volume control systems can be used: VAV (variable air volume) or CAV (constant air volume).

Insulation is used to protect the ventilation system from condensation, fire and to reduce airflow noise. The correct choice of insulation reduces heat losses in the system, and in the event of a fire does not contribute to its spread. Factors that affect proper airflow, such as poorly designed ducts, inadequate-sized ducts, or improperly adjusted valves and fans, can also be optimized.

You can also consider the installation of noise silencers in the ducts, which serve to reduce noise in the ventilation system. They are most often placed between the fan and the diffuser or exhaust fan, as well as before the diffusers themselves. The introduction of a strict maintenance plan — cleaning and replacing filters, ducts and fans — keeps the entire system in its best condition. As you can see, the list of tips for improving industrial ventilation is really long.

In conclusion — the improvement of the ventilation system means that everything will be in line with legal regulations and standards. It is very important to consult with HVAC (heating, ventilation and air conditioning) experts before making any improvements. Remember, everything must be properly calculated and selected to meet your expectations.

ATEX stands for equipment intended for use in explosives. It refers to dangerous or potentially explosive environments.

ATEX certified equipment is approved for safe use in such risky conditions and is usually marked with an Ex symbol.

ATEX fans are specialized industrial fans designed to operate in potentially explosive atmospheres, where the presence of flammable gases, vapors, fog, or dust creates a risk of explosion. They meet strict European ATEX directives and IECEx standards to prevent the formation of sparks or high temperatures that could cause ignition.

Types: there are axial (wall or roof) and centrifugal ATEX fans, adapted for different types of Assembly and air flow.

Certification: equipment must be clearly certified (ATEX designation) for specific hazard zones.

These fans are essential for safety as they extract flammable substances and provide a safe working environment.

How to choose a fan?

In selecting a fan, three key features are:

  1. Power: Determines the performance of the fan and its ability to overcome resistance in the system. When considering the power of the device, it is important to take into account the static pressure of the system because it represents the resistance to air flow. Greater resistance means the need for a more powerful device.
  2. Size: The fan must fit into the intended space while providing sufficient airflow for a given surface. The physical size of the space is also important because there must be enough room for proper suction and exhaust.
  3. Airflow: It is measured in cubic meters per hour and is crucial for efficient cooling or ventilation. This feature is also important in terms of energy efficiency, as it can significantly reduce operating costs in the long term.

Additional factors to consider:

  • Noise level
  • Energy efficiency
  • The ability to control speed
  • A suitable place to set up
  • Compatibility with additional equipment.

Modern fans often come with advanced control panels that allow fine-tuning of operation.

Each industrial application has unique requirements. For example, in mining and Metallurgy it is essential that fans are corrosion resistant, while in the chemical industry key models are resistant to aggressive chemicals. Energy-intensive industries prefer fans with advanced speed controls to provide optimal efficiency with minimal energy consumption.

Storage areas require larger models with high airflow, while smaller devices are needed for more accurate processes, but with more advanced operation control capabilities.

When choosing, think about specific challenges in your work environment:

  • Is it necessary to remove the dust?
  • Is there a need for humidity control?
  • Is there a risk of explosion?

The answers to these questions will help you narrow the choice and find the ideal solution.

Innovations and accessories: Fan technology is constantly advancing. Modern innovations include:

  • Smart control systems for remote control and real-time performance monitoring
  • Sensors that automatically adjust the operation of the fan
  • Advanced materials and design

Additional equipment can significantly extend the functionality of the fan:

  • Filters for removing particles and odors
  • Sound attenuators for noise reduction
  • Flexible pipes for directing air
  • Diffusers for uniform air distribution

Regular maintenance is key to the longevity and efficiency of your device, and it means:

  • Cleaning blades and casing
  • Checking and lubricating moving parts
  • Replacement of worn components.

Safety precautions to be taken:

  • The use of protective bars
  • Ensuring proper grounding
  • Regular check of electrical connections
  • Tracking signs of overheating or overheating

Choosing the right industrial fan can seem like a challenge, but with a few key information it becomes much simpler. Consider the specific needs of your industry, consider factors such as power and airflow, and do not hesitate to invest in quality equipment and accessories.

With the right choice of fans, you will ensure optimal working conditions, increase productivity and reduce long-term costs.
