Introducerea produsului

The throat explosion-proof fan has been tested to comply with GB3836.1/2010 "General Requirements for Explosive Environmental Equipment and Explosion proof Shell" d "Protection Equipment". The fan equipment operates continuously for 24 hours without any faults, with a long service life and worry free safety.

Using CAD, CFD, Solidwords and other analysis and development software, the fan efficiency is ≥ 80%, and some machine numbers are ≥ 85%. According to the fan similarity law, the speed and horsepower ratio have a cubic relationship, and the higher the efficiency, the more energy consumption is saved, which is conducive to high efficiency and energy conservation.

Customization of centrifugal fan size, connection of fan inlet to air duct or wall to pipe installation (installation form: vertical or horizontal), saving installation space. Adopting BT4 level explosion-proof motor and anti-static belt, stable and reliable operation.

Scenarii aplicabile

There are various ways to match the throat explosion-proof fan, including material replacement, research and development design, and material mechanics matching. It is suitable for flammable and explosive environments such as incinerators, catalytic combustion, RTO, RCO, VOCs organic exhaust, high-temperature exhaust, electronic semiconductor processes, and forced air supply. It can be customized one-on-one, with 24-hour online service from the manufacturer, long-term warranty, and lifelong maintenance.

A Throat Explosion-Proof Fan is a specialized ventilation device designed for explosive or flammable air environments where airflow must be directed through a confined duct or throat section. The term “throat” refers to the narrow airflow channel that allows controlled and concentrated ventilation, making this fan suitable for paint spray booths, chemical process lines, battery workshops, and flammable gas handling systems. Its primary function is to safely exhaust or circulate air while eliminating any risk of ignition inside or outside the airflow path.

The fan structure typically includes an explosion-proof motor, flameproof enclosure, reinforced steel or aluminum housing, and spark-resistant impeller. The impeller is dynamically balanced and constructed from anti-spark materials such as aluminum-magnesium alloy or coated carbon steel. The motor conforms to explosion-proof certifications such as Ex d IIB T4 or Ex d IIC T4, ensuring reliable isolation of electrical components from hazardous atmospheres. The wiring box and conduit entry adopt flameproof sealing joints with precise tolerances to prevent ignition transfer.

The throat configuration optimizes air velocity distribution, improving suction and exhaust efficiency while maintaining low noise and stable pressure. The fan’s volute and throat sections are designed using computational fluid dynamics (CFD) for smooth airflow transitions and minimal turbulence. Bearings are located outside the airflow and protected by air-tight seals, with lubrication systems designed for long continuous operation. Optional anti-static coatings or copper inserts can be applied to prevent static buildup.

Typical airflow capacity ranges from 1,000 m³/h to 60,000 m³/h, with static pressures between 500 and 3,500 Pa. Throat explosion-proof fans are suitable for both exhaust and supply air systems in hazardous environments containing vapors from solvents, paints, alcohols, or hydrocarbon gases. The combination of explosion-proof safety, aerodynamic optimization, and robust structure makes this fan an essential choice for facilities requiring high safety reliability and performance stability under potentially explosive conditions.
