Ducted Ventilation Fans Manufacturers

How do efficient ducted ventilation fans solve the problems of high temperature and dust in factories?

1. Core challenges of factory environment

High temperature problem:
Equipment heating and intensive operations lead to higher workshop temperatures, affecting worker efficiency and equipment life.
The cooling effect of traditional fans is limited, and systematic ventilation is required.

Dust problem:
Scenarios such as wood processing, metal grinding, and chemical production produce suspended particles, which are harmful to health and pose explosion risks (such as combustible dust).
It is necessary to capture, filter, and discharge polluted air in a targeted manner.

2. Solutions for ducted ventilation fans

1. Cooling in high-temperature environments
Forced air circulation: Introduce external cold air into high-temperature areas through the duct system, and discharge hot air at the same time (negative pressure ventilation principle).
Fixed-point cooling: Design local exhaust ducts for high-temperature equipment (such as furnaces and dryers) to quickly dissipate heat.
Energy-saving combination: It can be linked with the waste heat recovery system to reduce energy consumption.

2. Key Design of Dust Control
Source Capture: Install dust hood at dust generating point (such as cutting machine, feeding port), and connect fan through pipe to form negative pressure suction.
Graded Filtration: Pre-cyclone separator + HEPA filter (selected according to dust properties) to avoid fan wear and secondary pollution.
Explosion-proof Design: For flammable dust, use explosion-proof motor + conductive pipe to eliminate the risk of static sparks.

3. Key Points of Technical Selection

Air Volume and Air Pressure Calculation:
Select fan power according to workshop volume, ventilation frequency (such as 15-30 times per hour) and pipe resistance.

Pipeline Layout Optimization:
Reduce elbows and branches, and use circular air ducts to reduce friction loss.

Material Durability:
Stainless steel or FRP (glass fiber reinforced plastic) is used in corrosive environment.

4. Practical Application Cases

Case 1: A certain automobile welding workshop reduces dust concentration by 90% through ducted fan + filter cartridge dust collector.
Case 2: A variable frequency controlled piping system was installed in the high temperature area of ​​a food factory, and the temperature dropped by 8-12°C in summer.

5. Maintenance and cost-effectiveness

Regular cleaning: avoid dust accumulation and blockage in the pipes, and extend the service life.
Long-term benefits: improve compliance (OSHA/EPA standards), reduce employee sick leave, and improve equipment stability.
