Xin Feng Mini-Classroom -- Application of Stainless Steel Fans in Different Settings

The selection of stainless steel fan types should be based on the specific conditions of industrial buildings, prioritizing models that align with the original design parameters. Stainless steel fans and cooling water curtains should be positioned at consistent distances (ideally installed on both sides of the industrial building's gable walls) to achieve optimal natural ventilation. 

The exhaust system side should be located as far as possible from adjacent structures to prevent harm to nearby residents. Stainless steel fan pressure: This refers to the pressure increase achieved by overcoming friction resistance throughout the entire airflow delivery process. However, domestic fan models are typically rated based on the motor's rated power. while international standards allow slight increases. Residual pressure = fan motor rated power - friction resistance per sedimentation section. When delivered to ductwork, friction resistance is typically 7-8 Pa/m, increasing to 10 Pa/m at 90-degree bends. For heating, cooling, or fresh air supply systems, ensure heated or cooled airflow directs toward workers whenever possible. Stainless steel fans or sidewall fans are frequently employed for this purpose. For fire safety smoke exhaust systems, roof ventilators or elevated ductwork should be prioritized, hence duct fans are frequently employed. Note: Utilize natural airflow patterns whenever possible (fan direction and configuration must be effectively designed). Verify whether warehouse logistics goods are flammable or explosive (e.g., paint storage). Explosion-proof series fans must be selected. For noise sensitivity requirements, choose roof ventilators or eco-friendly centrifugal fans. For warehouse gas ventilation, consider international axial fans SF or exhaust fans FA.

Restaurant kitchen exhaust systems: For kitchens directly venting cooking fumes indoors (i.e., exhaust outlets within room walls), select SF axial fans or FA exhaust fans based on fume intensity. For restaurants and kitchens with heavy fumes requiring long ductwork with bends, centrifugal fans are strongly recommended (4-72 centrifugal fans offer broader applicability, while 11-62 low-noise energy-efficient centrifugal fans also perform exceptionally well). Centrifugal fans generate higher working pressure than axial fans, and since kitchen fumes bypass the motor, they facilitate easier maintenance and reduce frequent motor replacements. Kitchens with particularly intense fumes should consider implementing both solutions for optimal efficiency. Natural Ventilation for Advanced Venues For natural ventilation in high-rise venues like hotel restaurants, teahouses, cafes, entertainment rooms, and karaoke lounges, conventional fans are unsuitable. For small rooms connected to central ventilation ducts, lightweight, aesthetically designed plastic or aluminum axial fans with low noise and high airflow capacity are generally suitable.  For applications with stricter exhaust volume and noise requirements, fan enclosures are a viable option. 

These enclosures contain sound-absorbing cotton within the housing. When externally connected to the central ventilation ductwork, they achieve significant noise reduction and sound insulation. For blowers in fitness club rooms, prioritize industrial electric fans with high airflow capacity. Avoid SF-type rear-mounted axial fans due to considerations regarding external appearance and safety factors.
