Rooftop exhaust fans are designed to remove heat and odors from buildings to improve air quality and occupant comfort. Areas such as cafeterias, locker rooms, office spaces, restrooms and warehouses often have unique requirements specified by local codes and utilize a wide range of rooftop exhaust fans. To accommodate these various types of environments and ventilation systems, HINDUSTAN Fans offers a complete line of products to support every rooftop exhaust application. These applications can range from clean airstreams with minimal filtration all way to high density offices and health care facilities that must comply with extremely stringent regulations.
Propeller Roof Ventilators
Propeller roof ventilators provide cost effective, general purpose exhaust ventilation of commercial buildings as well as a large variety of industrial applications. Belt and direct drive models are available with cast aluminum, adjustable pitch or fabricated steel, fixed pitch propellers to meet specific application requirements.
Centrifugal Roof & Wall Exhausters
Centrifugal roof and wall exhausters are available in direct and belt driven models, featuring backward inclined, non-overloading centrifugal wheels for maximum efficiency and quiet operation. A variety of configurations are available for the exhaust of relatively clean air and grease-laden air.
Roof extractors are powered Ventilation Fans mounted on the roof to exhaust air forcibly they are provided with durable weather proof outer cowls. In this type of roof exhauster there is a continuous expulsion of indoor stale, hot and contaminated air thereby inducing fresh air into the enclosed space thus maintaining a healthy indoor air quality. These roof exhauster can be used in wall or window applications which experience severe wind conditions whilst all models feature a weatherproof outer cowl. These units are useful for extraction or air supply through the roof, usually preferable in Factories, D.G. rooms, Steel plant and Foundries and are also installed with ducts to extract air from a particular location. These roof exhauster provide effective extraction of air within the premises unlike the fans dependent on wind energy for effective performance.
An industrial roof extractor, also known as a roof exhaust fan or rooftop ventilator, is a device used to remove hot air, fumes, dust, and other airborne contaminants from industrial buildings, warehouses, factories, and other large facilities. These extractors are typically mounted on the roof of a building to expel stale air and improve indoor air quality. Here are some key aspects of industrial roof extractors:
Design and Size: Industrial roof extractors come in various sizes and configurations to suit different ventilation requirements. They are designed to withstand harsh environmental conditions, such as high temperatures, moisture, and debris, often encountered on rooftops.
Airflow Capacity: Roof extractors are engineered to move large volumes of air efficiently. The airflow capacity of an industrial roof extractor is typically measured in cubic feet per minute (CFM) and is selected based on the size of the facility, the type of contaminants to be removed, and the desired ventilation rate.
Materials and Construction: Industrial roof extractors are constructed from durable materials such as galvanized steel, aluminum, or stainless steel to ensure longevity and resistance to corrosion. The fan blades, motor, and housing are designed to withstand the rigors of continuous operation in industrial settings.
Efficiency and Energy Consumption: Energy efficiency is an important consideration when selecting an industrial roof extractor. Energy-efficient models, with features like variable speed control, high-efficiency motors, and aerodynamically designed fan blades, can help reduce energy consumption and operating costs.
Silencing and Vibration Control: To minimize noise and vibrations generated by the extractor during operation, some models are equipped with sound-insulating materials, vibration dampers, and noise reduction features. This is especially important in indoor environments where noise levels need to be controlled.
Safety Features: Industrial roof extractors may include safety features such as motor overload protection, thermal sensors, and automatic shut-off mechanisms to prevent overheating and ensure safe operation.
Installation and Maintenance: Proper installation of an industrial roof extractor is crucial to ensure optimal performance. Regular maintenance, including inspection of fan components, lubrication of moving parts, and cleaning of air intake vents, is essential to extend the life of the extractor and maintain efficient ventilation.
Industrial roof extractors play a key role in maintaining air quality, controlling temperature, and removing contaminants from industrial spaces. By effectively removing stale air and improving ventilation, these extractors contribute to a healthier and more comfortable working environment for employees while also helping to protect equipment and materials from damage caused by excessive heat and humidity.
