Finding solutions for unique applications is something the Eldridge team most enjoys. We recently helped a customer design a fire suppression system for a facility using a very different type of fan than found in standard applications. The customer requirements of air flow into and out of the building in the event of a fire …
In a head-to-head comparison, our customer selected the Eldridge Direct Drive Filtered Air Fan over options from a large, national competitor. We were able to recommend a solution that provided the customer with the required air flow performance at an overall better financial value. It was a great win for our customer and Eldridge Fan! Application …

Fans aren’t very effective at ventilating without moving propellers, but what is the best option for your application? At Eldridge, we prefer to use direct drive fans for most general ventilation applications based on selling thousands of fans in our 73 years of existence. In this article, I will compare direct and belt drive …
One of Eldridge’s long-time OEM customers needed to modify the design of an existing trailer turbine package to instead use a heavy gas fuel source. The customer needed our assistance in designing an external enclosure exhaust system that would evacuate any fugitive emissions from the heavy gas fuel supply. In undertaking this project, we faced …
Previously, in part one of this series regarding Air Density Impacts on Fan Performance, we determined how changes in humidity, temperature, and altitude can affect air density. We will conclude this two-part series by discussing the effects on fan performance caused by changes in air density. Effects on Performance Let’s create a very simple ventilation system …

At Eldridge, we use ASHRAE Standard Air Conditions to rate the performance of our Eldridge Fans. Standard Air has a density of .075 pounds per cubic foot at the conditions of 70º Fahrenheit, sea level barometric pressure of 29.92 inches of mercury, and 0% relative humidity. But what if my customer’s location is not at …

The design and equipment selection of a simple general building ventilation system design can be done with a high degree of accuracy using spreadsheet calculations. However, for more critical air flow systems, such as a wind tunnel, electric motor cooling system or a multi-unit diesel motor room, the level of precision required to get the …
When selecting fans for a customer’s application, we often hear, “Don’t select noisy fans.” What the customer really means to say is “don’t make my shop floor noise problem any worse than it is.” Improving our customer’s work environment by adding cooling air flow wouldn’t be value added if everyone is now required to …
Our first E-Hive Hood was installed around a year ago as part of an Eldridge designed gas pipeline compressor station ventilation system. They were installed as part of a gas pipeline compressor station ventilation system Eldridge designed. Our E-Hive Hoods were a key component in providing adequate air flow for the building while also …
