Ventilation system maintenance: how it works and when to intervene

What does ventilation system maintenance involve?

Effective maintenance of industrial ventilation systems is not limited to simple cleaning, but includes periodic checks of all components subject to wear, such as filters, impellers, bearings, and ducts.

Key aspects also include monitoring the system’s performance in terms of airflow and pressure, as well as checking safety devices.

These checks are especially crucial for systems dealing with contaminated air or smoke extraction systems, which require high performance to prevent fire risks and exposure to harmful substances.

When should ventilation system maintenance be performed?

Establishing exactly when to perform maintenance is critical to ensuring the continuous operation of the system and preventing failures.

In general, it is recommended to:

• Conduct semi-annual checks on systems with high usage intensity, such as those installed in industrial environments, professional kitchens, or technical laboratories.
• Act promptly if signs of malfunction occur, such as abnormal noises, reduced airflow, persistent odors, or visible dust buildup.
• Plan extraordinary maintenance after construction work, system modifications, or following exceptional events (fires, flooding, electrical failures, etc.).

Proper maintenance planning allows you to intervene before critical issues arise, avoiding production downtime, regulatory fines, and potential health risks for workers.

Ventilation system maintenance: what does the law say?

Ventilation system maintenance should never be carried out independently.

Specific tools and technical expertise are required to perform tests, inspections, and checks safely and in compliance with current regulations.

Maintenance activities include functional tests to measure parameters such as pressure, airflow, vibrations, and leaks, as well as internal visual inspections, often requiring operations at height or in confined spaces.

These are complex interventions that require technical preparation and the use of certified equipment.

For these reasons, Italian regulations, particularly Legislative Decree 81/2008, state that the maintenance of systems affecting the health of the work environment must be carried out by qualified personnel.

The same Decree mandates regular checks to ensure the proper functioning of systems and equipment.

Benefits of regular maintenance of industrial fans

Carrying out periodic and scheduled maintenance of industrial fans offers several benefits to companies, including:

• Energy efficiency: Well-maintained systems consume less energy, reducing operational costs and energy expenses.
• Increased productivity: Timely replacement of worn components prevents failures and ensures greater operational continuity, reducing the risk of system downtime.
• Regulatory compliance: Regular maintenance of ventilation systems ensures compliance with safety and hygiene regulations in the workplace.

Even with the adoption of predictive monitoring technologies, manual maintenance is essential for comprehensive control and to prevent potential malfunctions.
