The Pre-filter Hanging Low-Noise Fan Box is a integrated ventilation unit that combines pre-filtration system, low-noise fan and hanging structure. It is mainly used to filter outdoor air or circulate indoor air, remove dust and impurities in the air through the built-in pre-filter, and deliver clean air to the target area with low noise. The hanging installation design is suitable for spaces with limited floor area, such as ceilings, mezzanines and narrow workshops, which greatly improves the space utilization rate.

2. Core Technical Parameters

  • Airflow Range: 500-5000 m³/h (customizable according to project requirements)
  • Noise Level: ≤45 dB(A) (at 3m distance, standard working condition)
  • Pre-filter Grade: G4/F5 (optional, according to air quality requirements)
  • Installation Type: Ceiling hanging (with adjustable hanging bracket)
  • Fan Power: 0.75-15 kW
  • Operating Temperature: -10℃~40℃
  • Shell Material: Galvanized steel / Stainless steel (optional)

3. Core Features

3.1 Integrated Pre-filtration System: Equipped with a detachable pre-filter, it can effectively filter dust, hair and large particles in the air, prevent impurities from entering the fan and pipeline, extend the service life of the equipment, and reduce subsequent maintenance frequency.
3.2 Low-noise Design: Adopts high-quality low-noise motor and optimized impeller structure, combined with sound insulation and shock absorption materials inside the box, which significantly reduces the operating noise, meeting the noise requirements of commercial and residential areas.
3.3 Hanging Installation: Compact structure, light weight, equipped with adjustable hanging brackets, easy to install and disassemble, suitable for various limited-space scenarios, without occupying floor area.
3.4 Easy Maintenance: The pre-filter can be easily disassembled and cleaned, no need for frequent replacement; the fan and internal components are designed with easy access, which reduces maintenance time and labor costs.

4. Application Scenarios

The product is widely used in various commercial, industrial and public buildings, including but not limited to: office buildings, shopping malls, hotels, hospitals, schools, industrial workshops, warehouses, clean rooms and other places that require ventilation, dust filtration and low-noise operation. It is especially suitable for projects with limited floor space and high requirements for indoor air quality and noise control.
