Industrial fans for special applications
Industrial fans for special applications are designed to exceed the limits of standard ventilation, ensuring maximum performance, certified safety, and adaptability to extreme operating conditions. The range includes ATEX fans for potentially explosive environments, insulated versions for high temperatures and acoustic insulation, models for hot gases with integrated cooling systems, two- or multi-part configurations for easier maintenance, compact plug fans for small spaces, and reinforced heavy-duty solutions for demanding processes.
• Atex
ATEX fans
In industrial facilities where gases, vapors, mists, or combustible dust pose a risk of explosion, ventilation must ensure absolute safety. We distribute ATEX-certified fans from MZ Aspiratori, specifically designed to protect these critical environments.
Certifications and Regulatory Compliance
Each fan strictly complies with the most stringent European regulations: the ATEX Directive 2014/34/EU for equipment intended for explosive atmospheres and the Machinery Directive 2006/42/EC for machinery safety. Certification by TÜV Nord Cert GmbH of Hannover guarantees the reliability of our solutions through comprehensive ATEX certificates and detailed declarations of conformity.
Applications and Zone Classification
The fans operate safely in potentially explosive atmospheres, both where explosive atmospheres are present frequently (zones 1/21) and occasionally (zones 2/22). This versatility allows for the safe transport of potentially hazardous materials in a variety of operating conditions.
Customized Selection
Each installation requires a specific analysis. We assess the environmental risk according to Directive 1999/92/EC, considering the frequency of explosive atmospheres formation to select the most appropriate fan for your needs.

• Coinbentati
INSULATED fans
Insulated fans are the ideal solution where high temperatures and noise control require specialized systems. These fans ensure operational safety, energy efficiency, and regulatory compliance even in the most critical conditions.
Hub Insulation
Hub-only insulation is designed for transporting fluids with temperatures above 150°C. This configuration creates an effective thermal barrier that isolates the high-temperature internal zone from the ambient temperature external zone, protecting critical mechanical components and ensuring operator safety. For extreme applications in the 200-300°C range, our engineering department develops customized solutions on a case-by-case basis. This insulation cannot be applied to directly coupled fans equipped with size 63 motors.
Full Casing Insulation
Full casing insulation uses semi-rigid panels of biosoluble rock wool, a material compliant with Directive 97/69/EC obtained from the fusion of natural rocks. This solution is suitable for operating temperatures above 300°C and offers two advantages: it drastically reduces the fan’s surface temperature, improving workplace safety, and significantly reduces noise transmission, contributing to acoustic comfort and regulatory compliance. The standard thickness is 60mm, with 80mm, 100mm, and 120mm options to meet specific thermal and acoustic insulation needs.
• Hot gases
HOT GAS fans
Transporting fluids with temperatures above 60°C is a complex technical challenge that requires equipment specifically designed to withstand intense heat and ensure reliable performance over time.
Integrated Cooling System
We offer specialized industrial fans designed to operate effectively in extreme thermal conditions. The distinguishing feature of these systems is the integration of a dedicated cooling device: an auxiliary fan installed on the impeller hub that ensures continuous heat dissipation.
Automatic Thermal Protection
This system keeps critical mechanical components within safe temperature parameters, preventing overheating that could compromise performance or cause premature failure. The cooling fan operates automatically while the main fan is running, ensuring constant thermal protection without requiring manual intervention or additional monitoring.
• Two or more parts
TWO OR MORE PARTS fans
For large fans, maintenance often poses a complex challenge in terms of costs and downtime. The most effective solution is a modular design with a self-supporting casing and drive-side extraction.
Modular Configuration
This special configuration allows the impeller assembly to be completely removed without having to disconnect the fan from the process system. The self-supporting casing ensures independent structural stability, while the side extraction system allows quick and safe access to internal components requiring maintenance, such as bearings, the impeller, and the drive shaft.
Operational Benefits
During routine or unscheduled maintenance, there is no need to dismantle piping or completely shut down the system. This approach dramatically reduces downtime and associated costs, allowing for faster and more efficient interventions without compromising the operational continuity of the production process.
• Plug fan
PLUG FAN fans
Plug fans are compact units characterized by the absence of a traditional casing, specifically designed for integration into systems with space limitations where a standard industrial fan cannot be installed.
Typical applications
These solutions are used in industrial ovens, air distribution plenums, paint booths, and air handling units, where compactness and ease of integration are key requirements. Despite their small size, they use the same impellers as standard fans, ensuring proven reliability and performance.
Performance and configurations
Final performance depends on the characteristics of the system into which they are integrated, as the absence of a casing modifies the aerodynamic behavior compared to traditional fans. They are available in various construction configurations: executions 4 and 5 for direct-coupled models and execution 9 for belt-driven models.
High-temperature versions
For high-temperature applications, they can be supplied in a hot gas version with an auxiliary cooling fan, with or without an insulated panel. This configuration allows safe operation with operating temperatures up to 300°C in the impeller area, extending the versatility of these compact systems to the most critical thermal environments.
• Heavy duty
HEAVY DUTY fans
For industrial applications requiring operation at very high pressures or in particularly severe operating conditions, ventilation solutions with structural features superior to conventional standards are required.
Reinforced Construction
Heavy-duty fans are designed and built with increased sheet thicknesses and additional structural reinforcements to ensure mechanical resistance and durability even under the most demanding conditions. This reinforced construction allows them to withstand intense mechanical stress, high vibrations, and operating pressures exceeding the limits of standard fans.
Application Sectors
This design is the ideal solution for industrial sectors such as metallurgy, cement plants, petrochemical plants, and mining processes, where equipment reliability is critical for production continuity and operational safety. Structural robustness ensures consistent performance even under continuous workloads and extended operating cycles.
