Heating, Ventilation, and Air Conditioning (HVAC) systems are equipped with fans, which serve as cooling and air circulating devices. Fans are of great significance in HVAC systems. However, not each cooling or ventilation activity is performed by one type of fan. HVAC systems are often designed for result-centric output and therefore for different activities, and performance parameters, different types of fans are used in an HVAC system. There are ideally two types of industrial fans, namely, axial fans and centrifugal fans. These two fundamental types are further categorized based on design, and performance. Owing to the same, the list of the types of fans used in HVAC systems becomes lengthy. This post introduces different types of fans used in the HVAC systems and the specific roles of each type of fan.

Fan grids or fan walls are a common sight in industrial cooling and ventilation systems. As the name suggests, the grids may feature multiple fans arranged parallel to each other. These parallel arranged fans help overcome the low air throughput of fans in industrial or commercial cooling and ventilation units. Other than overcoming the lack of sufficient air, there are multiple aspects in which the fan grid solutions with more than one fan can be beneficial. This article discusses how using multiple cooling fan units in a fan grid solution can be beneficial

HVAC is an acronym for heating, ventilation, and air conditioning. The HVAC systems are an integral setup of three processes - heat addition, heat extraction, and conditioning. Certainly, HVAC systems are installed almost everywhere including homes, industrial locations, food processing stations, organic warehouses, marine systems, and so on.

Fans and blowers may seem the same to most people, and at times may be used interchangeably. However, fans and blowers are technically different in terms of their working, structure, function, and applications.

An axial fan is a type of industrial fan which helps cooling of machines and devices. They facilitate parallel air flow to the rotor shaft, which offers ventilation to the device and prevents overheating. This post discusses the working and uses of AC and DC axial fans.

Depending on the applications and industrial requirements, we can see many types of industrial fans. Among these, industrial axial fans and centrifugal fans are the two popular ones. These serve a similar purpose but their constructions and functions differ in several ways. This post discusses the differences between these two types of industrial fans.

There are several types of industrial fans depending on several criteria. However, depending on the type of power supply, the industrial fans are distinguished into two types - AC fans and DC fans. Therefore, this post gives insights about the difference between AC fans and DC fans, along with criteria to select one of these types for specific applications.

There are a number of factors one needs to consider for their maintenance. This post offers tips for maintenance of AC and DC blower fans.

Medical facilities are sensitive, thus, need specialized devices. Air conditioning and ventilation are one of the most important requirements in medical facilities. This is because specific thermal conditions need to be maintained throughout the hospital. Therefore, the HVAC management for facility managers becomes a tough task. Additionally, taking care of sensitive health conditions of patients and a reduction in power consumption on the cooling and ventilation system together become a hectic task.

Over the years, various types of industrial fans have gained immense torque across industries. Radial fans are one of the important types of industrial fans to have received wide acceptance. These fans are used in factories, mines, and commercial buildings. A radial fan is a mechanical device that features an impeller, which is powered by an electrical motor.
