Centrifugal fans or blowers have a wide variety of process air applications. When selecting a centrifugal fan wheel for a particular application, here are three most common types to choose from: Forward Inclined Backward Inclined Radial In this week’s blog, I will discuss the characteristics of each type of wheel and the applications for …

In the second part of this three part series, I discussed the fluid flow analysis software and the three step process that we use to build models. In the third and final part, I’ll go through an actual ventilation system design project that we modeled in the FFA software. Example Project The ventilation system that …

In the first of this three part series, I discussed the differences between FFA and CFD software and why the FFA software is better for our analytical needs because we can input an entire fan curve. In part two, I’ll go over the three steps that we use in building ventilation system models in our …

At Eldridge, we are in the business of solving the most difficult ventilation problems. To do that, sometimes we will use fluid flow analysis (FFA) software to solve for the flow, pressure and velocity of a complex ventilation system. Some customers will ask if we also use computational fluid dynamics (CFD) software. They are always …

In part 2 of this series, we used acoustic calculations to evaluate whether the combined noise from the interior of a building and a supply fan exceeded a given noise limit. In this third part, we will analyze the use of sound reduction techniques to bring the combined noise in under the noise limit. Sound …

When designing a ventilation system, it is often as important to meet acoustic requirements for the system as it is to meet requirements for air flow and pressure. We see this a lot when we are designing ventilation systems for gas pipeline compressor stations. The specifications for the station will often provide a maximum decibel …

At Eldridge, we love industrial ventilation problem solving. A problem solving approach to meeting a customer’s needs is part of our company culture and for those that have been with Eldridge for a long time, you could say that it is in their DNA. The fact that we been granted seven patents is a true …

Most food processing companies take the health and safety of their people and products very seriously. However, the COVID-19 pandemic has exposed weaknesses in their sanitation and hygiene regimes used to prevent person-to-person and person-to-product transmissions. The periodic cleaning processes used to mitigate these transmission pathways for listeria and salmonella are ineffective when an airborne …

The best way to help employees beat the summer heat is to have a good ventilation system. A poorly ventilated building can cause the inside temperature to exceed the ambient outside temperature by as much as 20 deg. F. Not only does the excessive heat pose a health risk, it has a real impact on …
