Sound plays a crucial role in our daily lives. Yet many people don’t fully grasp the difference between sound pressure and sound power. These two concepts are fundamental to understanding how sound behaves and is measured. Sound pressure level, often expressed in decibels (dB), is what our ears perceive and can change with distance from …

A well-designed local industrial exhaust system can effectively control harmful fumes, dust, and other airborne hazards. Unlike general ventilation, which circulates air throughout a space, local exhaust ventilation targets specific contaminants at their source. This direct approach is crucial for protecting worker health and complying with safety regulations. Today, we will discuss the key components …
Choosing industrial fans hinges on their ability to move a specific air volume against the ventilation system’s total static pressure. But how much static pressure should we add for the fan itself? Let’s explore the three types of pressure losses caused by fans – friction, dynamic, and component – and which ones to include in …
Gas turbines are powerful machines that generate electricity and drive industrial processes. They work by burning fuel to create hot gases that spin a turbine, and like any engine, they produce a lot of heat. That’s where ventilation systems come in – they keep gas turbines running smoothly by removing excess heat and ensuring optimal …

Before the 1980s, controlling fan motor speed was limited to two-speed motors, which were costly and had long production times. The advent of variable frequency drives (VFDs) revolutionized this, offering cost-effective and nearly infinite speed control options. This article will address common questions about using VFDs for fan motor speed control and will explain the …
At Eldridge, our passion is solving the most difficult ventilation problems. To do that, we often will use fluid flow analysis (FFA) software to solve for the air flow, pressure and velocity. We have used FFA for simple ventilation systems such as a manufacturing facility as well as for more complex applications such as an …

Noise pollution is a significant health and safety hazard in metal fabrication facilities. Metalworking processes, such as sawing, pressing, and grinding, generate a variety of noises that contribute to this hazardous environment. This makes noise control for industrial ventilation systems essential for your shop. Exposure to chronic loud noise levels exceeding 90 decibels can lead …

As vessels crucial for offshore oil and gas exploration, drill ships require robust ventilation systems. These systems address critical environmental factors that can impact crew health and help mitigate operational hazards. Industrial fans are central components within these ventilation systems. Their proper selection and configuration influence air quality, temperature control, and efficient fume removal. Today, …

One of the key factors to consider when creating an industrial ventilation system is whether the facility needs to maintain a positive or negative pressure environment in order to ensure the safety of people, products, and processes. In this week’s blog post, we will explore the advantages of each option, the factors that should be taken …
