FB series explosion-proof oscillating fan, industrial grade explosion-proof electric fan

Description :

  The FB series explosion-proof oscillating fan is an industrial ventilation equipment designed specifically for flammable and explosive hazardous environments, mainly used in places such as petroleum, chemical, pharmaceutical, etc. where Class II A, B, and C explosive gas mixtures exist. This explosion-proof electric fan is designed with a special explosion-proof structure to effectively prevent internal electrical sparks from igniting external combustible gases, solving the problem of safe ventilation in high temperature, high humidity, and corrosive environments, ensuring air circulation and personnel safety in the work area. It is a necessary security facility for typical Zone 1 and Zone 2 hazardous conditions.

  The explosion-proof electric fan casing is usually made of high-strength aluminum alloy die-casting or steel plate welding, and the surface is treated with high-voltage electrostatic spraying, which has excellent anti-corrosion and anti rust properties. The motor is selected as a dedicated explosion-proof three-phase asynchronous motor with an insulation level of F and a protection level of IP54 or above, ensuring long-term stable operation in harsh environments. The impeller has undergone precise dynamic balance correction, ensuring smooth operation and low noise. The product complies with the national standards GB3836.1-2010 and GB3836.2-2010 for electrical equipment for explosive environments, and has been certified by the National Explosion proof Electrical Product Quality Supervision and Inspection Center to ensure that all explosion-proof parameters meet the standards.

  When selecting the FB series explosion-proof oscillating fan, it is necessary to clarify the division of hazardous areas (Zone 1 or Zone 2) and gas groups (IIA, IIB, or IIC) on site. If there are high-risk gases such as hydrogen and acetylene on site, IIC explosion-proof products must be selected; If it is only for gasoline, acetone and other environments, IIB level can meet the demand. Unlike ordinary industrial fans, explosion-proof electric fans are strictly prohibited from operating beyond the rated voltage or frequency, and the explosion-proof joint surface cannot be disassembled at will. When purchasing, it is necessary to confirm the installation method (floor standing or wall mounted) and the range of shaking angles to ensure coverage of the required ventilation area and avoid safety hazards or insufficient efficiency caused by improper selection.

  When installing the FB series explosion-proof oscillating fan, it is necessary to ensure reliable grounding, and the inlet should be sealed with a matching explosion-proof gland to prevent gas from entering the wiring chamber. In daily maintenance, it is necessary to regularly clean the dust accumulation on the blades, check whether the fasteners are loose, especially the integrity of the explosion-proof surface, and strictly prohibit collision or scratching of the explosion-proof joint surface. If overheating, abnormal noise or excessive vibration are found in the motor, the machine should be stopped immediately to check the condition of the bearings and windings. It is recommended to conduct an insulation resistance test every six months to ensure electrical safety. Proper maintenance can significantly extend the service life of explosion-proof electric fans and ensure the continuous safe and stable operation of the production environment.
