Overview
Gardner Denver provides durable and cost-effective solutions for the Power Generation industry, specializing in multistage centrifugal blowers for wet flue gas desulfurization (FGD). These blowers are essential for introducing air to accelerate oxidation in the spray tower or absorber, a critical step in removing sulfur dioxide from flue gas.

Historical Context
In the 1970s and 1980s, high-speed single-stage blowers were prevalent for FGD. However, Gardner Denver's acquisition of Lamson and Hoffman in the 1990s positioned them as leaders in multistage centrifugal blowers, which are now preferred due to their reliability, lower maintenance, and comparable efficiency.

Product Specifications
Gardner Denver offers 22 models of multistage centrifugal blowers, with the largest three being primarily used in FGD projects. These blowers are designed for efficiency, tested for performance, noise, and vibration, and comply with ASME, ISO, and other standards. Key features include multiple baffle rings for efficiency, balance pistons for longer bearing life, and low-speed operation for reduced downtime.
