Workshop exhaust fan
Solution to Negative Pressure Fan Noise: Reason Three: The vibration damping pad or fixing screws on the fan base are too tight, losing their damping effect, causing vibration noise during operation.
Solution: Adjust the tightness of the vibration-damping pad screws on the negative pressure fan base to ensure the base surface is flat. Reason four for solving negative pressure fan noise: Low power supply voltage causes abnormal sounds and vibrations when the negative pressure fan starts or operates.
Solution: Keep the power voltage within the rated range. Typically, a voltage stabilizer or power voltage regulator can be used to stabilize the voltage.
Fan and Water curtain Ventilation Cooling System Exhaust Fan
Solution to Negative Pressure Fan Noise: Reason Five: Wind blades of the negative pressure fan collide with the fan housing (cover).
Solution: Adjusting the negative pressure fan noise. Reason six: Poor fan motor bearing, loose base screws of the axial flow fan, loose blade fixation on the shaft, and too small gap between the blade tip and the housing.
Solution: Replace the motor bearing of the vacuum fan, tighten the base and screws on the shaft. Adjust the gap between the blade tip and the housing according to production technical requirements, generally not exceeding 1.5% of the blade length. Reason seven for solving vacuum fan noise: loose base screws of the vacuum fan, poor blade assembly, excessive speed, loose fixed screws on the shaft, etc.
Solution: Secure the base and screws on the negative pressure fan's shaft. Reassemble and adjust the impeller gap according to technical specifications.
High-volume exhaust fan
The negative pressure fan purifies air, though it also uses water for air purification. However, it does not cause secondary pollution; instead, it makes the air blown out even fresher, creating a more comfortable indoor environment.
Why can exhaust fans clean the air? Have you guys ever taken a look into it? Well, it's mainly due to the application of technology and materials. Exhaust fans primarily utilize two technologies: recirculating clean water and recirculating sterilization; as for materials, they use PP meltblown filter cores, which can effectively remove impurities from the water. Additionally, when used together with silver-loaded ceramic balls, they can effectively eliminate bacteria in the water.
Combining these two technologies effectively removes bacteria from water, thereby maintaining fresh air. Additionally, in terms of air purification, the negative pressure fan's PET platinum-coated dust filter is highly effective at preventing oil and removing stains, as well as filtering out dust and bacteria. Moreover, the silver fiber mesh can eliminate bacteria in a short time and produce chemicals to eliminate odors in the air, ensuring the cleanliness of the room.
Not only do they offer low operating costs, but they also have advantages such as high airflow volume and long service life. It's precisely these benefits that have made vacuum fans quite popular and supported by many businesses, now becoming the first choice for modern cooling equipment.
