Scenarii aplicabile

Explosion proof centrifugal fans are mainly used in places without acidic or alkaline components such as pharmaceuticals, petroleum, chemical, electronics, metal processing, PCB circuit boards, electroplating, and other flammable and explosive gases. They are also suitable for various working conditions such as exhaust and air supply in multifunctional applications. The fan operates smoothly, increasing profits and saving costs for you. They are the preferred choice for centrifugal fan models.

An Explosion Proof Centrifugal Fan is a specialized ventilation unit designed to safely handle flammable or explosive gases, vapors, and dust in hazardous environments. The fan adopts a centrifugal impeller structure that converts mechanical energy into kinetic energy and pressure energy of the gas. During operation, air or gas is drawn axially into the impeller through the inlet, accelerated by the rotating blades, and discharged radially through the volute casing. The critical design feature of this fan is the explosion-proof structure that prevents ignition sources from forming inside or outside the housing.

The casing and impeller are typically made of high-strength carbon steel or anti-static aluminum alloy to prevent mechanical sparks caused by friction. All rotating parts are balanced dynamically to minimize vibration, while the motor and junction box are explosion-proof grade, usually conforming to international standards such as Ex d IIB T4 or Ex d IIC T4. The motor enclosure is completely sealed to isolate electrical components from the surrounding atmosphere. The fan shaft passes through flameproof joints with precise tolerances to prevent ignition transmission.

To further ensure operational safety, the bearing housing is externally mounted for easy maintenance and thermal dissipation. Lubricants used are non-sparking and anti-static. Inlet and outlet sections are equipped with anti-spark copper rings or stainless-steel liners. Electrical wiring is executed using armored explosion-proof cables and glands. Depending on the classification of the installation zone, the fan can be configured with direct drive or belt drive systems, both engineered for spark-free performance.

Explosion proof centrifugal fans are commonly employed in industries such as chemical processing, petroleum refining, gas plants, paint manufacturing, spray booths, and battery production. They are also suitable for underground tunnels and grain handling systems where combustible dust may accumulate. The airflow range can be customized from 500 m³/h up to 100,000 m³/h, and pressure levels are typically between 200 and 2,500 Pa. By integrating explosion-proof safety with efficient aerodynamics, these fans provide a reliable and durable solution for hazardous air handling applications.
