Introduction
The Inlet Funnel Explosion-Proof Centrifugal Fan features a trumpet-shaped air inlet structure and an aluminum alloy explosion-proof housing, making it widely used in high-risk industrial settings such as petrochemical plants, spray workshops, and dust treatment facilities.
Features
Explosion-proof Safety
The fan adopts a high-strength aluminum alloy integral housing and is equipped with an explosion-proof motor and a sealed electrical box that meet the Ex d IIB T4 Gb standard, which can effectively isolate electric sparks and high-temperature components, ensuring that the equipment operates safely in a Class IIB combustible gas environment with a maximum temperature of 135°C.
Efficient Air Intake
This product adopts a trumpet-shaped air inlet design structure. Compared with the traditional straight pipe air intake, the air intake efficiency is increased by about 30%, which can quickly replenish a large amount of gas and reduce airflow turbulence and pressure loss.
Powerful Air Delivery Capability
Equipped with a 7.5–400kW high-performance explosion-proof motor and a dynamically balanced centrifugal impeller, the Inlet Funnel Explosion Proof Centrifugal Fan can achieve a maximum air volume of 100,000 m³/h and a full pressure of 10,000 Pa.
High Connection Flexibility
Adopting a standard circular inlet and outlet design, supporting flange docking or slide-in soft connection, this centrifugal fan can be directly matched with a standard duct system without additional modification.

FAQ
Q: In which industries is the inlet funnel explosion-proof centrifugal fan mainly used?
A: This type of explosion-proof centrifugal fan is primarily used in flammable and explosive environments such as petrochemical plants, food processing facilities, chemical and pharmaceutical factories, and underground mining operations.
Q: What is the main role of this fan in the petrochemical industry?
A: In the petrochemical sector, the fan ensures effective plant ventilation, prevents the accumulation of hazardous gases, and supports the safe handling of flue gases and exhaust extraction, contributing to a secure working environment.
Q: Why is this equipment necessary in the chemical pharmaceutical industry?
A: In chemical and pharmaceutical applications, the explosion-proof fan provides controlled airflow to cleanrooms and sterile zones, maintaining safe and contamination-free conditions and minimizing explosion risks during sensitive reaction processes.
Q: What is its primary function in underground mining?
A: In mining operations, the device is used for deep shaft ventilation and airflow regulation, helping to lower concentrations of combustible gases and thereby enhancing miner safety in enclosed underground environments.
Q: What is the working principle of the equipment?
A: This centrifugal fan operates by using centrifugal force to accelerate the intake air, transforming kinetic energy into pressure energy to achieve efficient and consistent ventilation in hazardous areas.
Q: What are the special requirements for the impeller material?
A: The impeller is typically constructed from high-strength, spark-resistant aluminum alloy, ensuring safety, durability, and performance in explosive or high-temperature conditions.
Q: What materials are commonly used for the fan housing?
A: The casing is usually made of high-hardness, corrosion-resistant materials, such as stainless steel or galvanized steel, to ensure long-term durability in corrosive or industrial environments.
Q: Can this machine operate in high-temperature environments?
A: Yes. The fan is built with heat-resistant components and incorporates a flame-retardant structural design, enabling it to function reliably under high-temperature conditions.
