Commercial summer fans

Commercial grade certified fans

Many electrical appliances are designed for household use and are also classified as such. However, since commercial use places completely different demands on the design and use of such devices, their use in commercial or industrial applications can sometimes be associated with considerable risks.

For example, a plastic table fan in a large industrial production facility in Hamburg caused a fire at night that damaged the entire production hall. What had happened? Due to the high temperatures at home, an employee had brought a plastic table fan from the hardware store in order to reduce the heat on the production machine somewhat and improve his working environment. The safety specialist was not informed about this. At the end of the employee's shift, he forgot to turn off the fan. The combination of self-heating of the motor and the waste heat from the production machine set the fan on fire, which then continued accordingly. The fire remained confined to the machine area, but the entire hall became smoky. People were fortunately not harmed.

Testing according to DGUV Section 3

The company / employer is responsible for ensuring the safety and health of employees at work.

This includes ensuring that all electrical equipment, whether stationary or mobile, complies with the requirements of the accident prevention regulations (BGV/GUV-V A 3). They must be installed, operated, maintained, serviced and tested in order to minimize the risk of accidents and fire. Electrical safety must be checked at initial commissioning and at regular intervals in accordance with DGUV Section 3.

In order to prevent hazardous situations, we check during the development of our „commercial fans“ whether the product can withstand the expected operational stress. For this purpose, the current Machinery Directive 2006/42/EC, Part 1, is used as the basis for assessing suitability.

Our commercial certified fans differ from our „normal“ fans in terms of increased safety.

Cable: we use for devices with the addition „Safe-Line“ (SL) supply cables H07RN-F for high mechanical loads, also suitable for permanent outdoor use rubber hose cable with a rated voltage of 750 V (conductor against conductor; 450 V against ground). For devices für use in storage and operation, a supply line H05RN-F is used.

Switch: unlike most table and floor fans, our CasaFan SafeLine series (SL) units have a circuit breaker or the step switch in the zero position that disconnects the motor from the mains at all poles. This reliably prevents accidents and fires when the unit is switched off, even in adverse ambient conditions.

Motor: When designing the motors for these products, we make sure that there are sufficient reserves in the dimensioning to keep the motor heating as low as necessary. This reduces the risk of „burning out“ of the motor and increases the overall service life. The motor has thermal overload protection that trips at lower temperatures than our household products. If the motor overheats, whether due to a defect in the unit or an outside influence, this fuse inserted into the motor winding reliably interrupts the power supply, preventing further damage.
