Filtration and Separation
Bagfilter (ECOpuls)
Bagfilters are the technology of choice when low dust content is needed for gas cleaning. Their ability to remove large dust Ioads on a non-selective basis has made them essential for many applications.
GEA’s unique Low-Pressure High-Volume Technology is especially applicable for treating large gas flows and achieves nearly zero emissions with the lowest cost of ownership. The GEA ECOpuls Filter (Elliptical COncentrical puls Filter) combines the dedusting performance of conventional bagfilters with the reliability, extended lifetime and energy saving capabilities of low-pressure cleaning technology.
This bagfilter technology has been optimized for large volume flows and requires a minimum of pulse air equipment.
A reduced amount of individual parts, its high gas-cleaning efficiency and the plant’s small footprint call for a minimal investment for the GEA ECOpuls filter solution.
Thanks to GEA´s low pressure technology, the air used for bag cleaning needs to be compressed to only 0,8 bar (g). This low compression rate is achieved through reliable and energy efficient root blowers instead of using a conventional high/medium pressure system with a substantially higher energy consumption.
The low overall pressure drop of the GEA ECOpuls filter and the extended filter bag lifetime help reduce further operational costs.
As a result, the GEA ECOpuls filter is not only technologically superior, but also offers the lowest cost of ownership.
The Bagfilter can be carried out with multiple compartments to enable on-line maintenance as well.
The ECOpuls Filter is ideally suited for its combination with other emission control tasks like the separation of SO2, Mercury and NOx.
Changes in the upstream process or lower clean gas dust loads often lead to switch from a dry electrostatic precipitator (ESP) to a Bagfilter. GEA is an expert for such Bagfilter components´ retrofits installed in existing ESP casing.

Working Principle
Working Principle of Bagfilter (ECOpuls)When dust-laden gases flow through a porous layer of fabric or felt, the dust is separated from the carrier gas and deposited on the filter medium. It is re-moved periodically and falls into the dust hopper.
The filter materials used are woven or non-woven fabrics made from natural or man-made fibers as well as inorganic fibers (glass, mineral or metal fibers). A detailed description of the working principle can be watched here:
