Enclosures often need ventilation because internal components continuously radiate heat. With active ventilation, hot air is forced out and the lifespan and the reliability of the equipment are increased. A cost effective solution to channel fresh ambient air to lower internal temperature is a fan filtered system. Fan filters prevent the risk of overheating and protect electronics from the ingress of dust, damaging
Depending on the applications, a fan filter can be use in varying sizes and configurations for both indoor or outdoor installation to remove unwanted heat buildup inside the enclosure or electrical cabinet. In order to extend the life of the unit, filters mats should be cleaned, re-used or replaced dependent on the operating environment.
The FF series fan filters offered by Fandis North America offer a fast mounting tool-less system, which allows the unit to be easily clipped onto the enclosure. FF series improve the protection from both dust and water (IP54/IP55) that may have access to the internal components, as well as, when required, shield against EMC/RFI emissions or withstand outdoor use (UL Type 3R) . They are available from 107mm to 325mm square, in standard color RAL 7035.
FF series provides filtered cooling air to enclosures. There are different possibilities for use of fan and fan filter to protect your installation, depending on environmental conditions.
Roof exhaust units are used in restricted spaces to extract warm air from the top of an enclosure. They are constructed from plastic with aluminum top, which helps better dissipate the heat generated by the fan.
This cover is particularly suitable for outdoor application or food industry, by protecting against water jets and climatic influences. It reaches a rating of IP56, when installed above the fan filter.
This plastic frame allows the fan filter installation in a semi built in position on the electrical cabinet, reducing the internal dimensions. It is ideal when space within the enclosure is limited.
NC Thermostat controls the heater and turns it on when the internal temperature falls below a set point. In doing so, it keeps the temperature warm enough to prevent moisture building up on the electronic components.
Hygrostats monitor the humidity levels within an enclosure and trigger the heater to stop the temperature going below the dew point. The advantage of using a hygrostat is the reduced energy consumption. The advantage of using this regulator is a considerable amount of energy saving.
If an enclosure can be susceptible to large temperature fluctuations, heater and fan filter are used together to manage the shift between daytime warming and nighttime
