Ventilation with fan filter is the most suitable enclosures solution when the external temperature is lower than the internal one, during the whole day, and when the panel is located in environments not particularly aggressive or corrosive.
How to guarantee excellent performance of the fan filter unit in an electrical enclosure?
However, if you want reliable and long-lasting performance of the fan filter unit, it’s essential to pay attention to some aspects. Let’s see them together.
Correct operation of the fan
If the fan does not work optimally, the performance of the fan filter unit is also compromised. A solution could be to monitor the air flow with an effective thermal management system, such as the Sensis smart device for enclosures.
Keep a correct ventilation inside the electrical panel
Keeping the ventilation filters free and clean ensures a better ventilation of the panel, preserving the efficiency of the electrical and electronic devices inside. To ensure optimum air circulation, no objects must obstruct the ventilation grids, respecting the appropriate distances from walls, obstacles or other machinery, or alternatively, opt for a solution designed specifically for limited spaces.
Furthermore, effective air filtration is also subject to a correct cleaning of the filter mats, especially in areas of installation characterized by strong presence of dust and pollutants.
Check the seal of the fan filter unit
Checking the integrity and sealing of the gaskets of the fan filter periodically is essential.The environmental seal degree indicated by the protection ratings is also an increasingly qualifying element for gaskets mounted on electrical enclosures.
In the case of the Virdis FF series, for example, the polyurethane foam gasket is industrially placed in the appropriate seats, ensuring excellent quality and sealing result.
Correct positioning of the filter assembly
Depending on the application requirement, it’s important to position the fan filter adequately to facilitate the efficient dissipation of the heat generated by electrical components inside the enclosure.
It’s also necessary to combine the fan filter unit with a filtering aeration grid and to switch the fan on with a thermostat when temperatures are too high.
