Drop Test

Overall Product Quality Inspection

Is the fan fitted with two or more well-balanced blades made from metal or other suitable material so as to be reasonably free from vibration? Yes
Are the bearings of good quality and lubricated appropriately for use? Yes
Is there an automatic shutdown mechanism when fan blades are impeded? Yes
Is the fan clearly marked with a standard nameplate? Yes
Notes About Nameplate N/A
Does the fan's packaging include appropriate information? Yes
Notes About Packaging Missing precaution text or signage
Does the fan come with appropriate documentation? No
Notes About Documentation Missing warranty information
Are the fan blades appropriately guarded in accordance with Clause 20.101 of "IEC 60335-2-80: Household and similar electrical appliances. Safety. Particular requirements for fans."? No

Off-Grid Compatibility
