FS Flat Bag Dust Collector with Secondary Filtration

The FS series dust collector, equipped with horizontally mounted flat bag filters, is a compact and high-performance filtration solution designed with advanced air cleaning technology. The system is engineered to handle high dust concentrations, fine particulate matter and elevated gas temperatures while maintaining efficient filtration performance.

Its compact design allows for quick installation and easy transportation to industrial sites, often requiring only a single container-sized flatbed delivery. Designed for demanding applications across industries such as foundries, smelters, asphalt plants and other heavy process operations, the FS flat bag dust collector delivers effective air pollution control in a space-efficient and installation-friendly package.

Application:

Aluminum melting furnaces, AlO₂ transport and silos melting furnaces.

Downflow filtration, cleaned by reverse air
Air flows through the filter from top to bottom. Dirty gas enters through the inlet hood, where baffle plates slow solid particles and distribute the dust load evenly along the full filter length.

Dirty gas enters and slows
Gas enters through the dirty gas hood. Baffle plates reduce particle speed and ensure even distribution of the dust load across the filter.

Downflow through the bags
Gas flows down through horizontally arranged filter bags to the clean gas side, where dust is held back by the filter media and forms a filter cake.

Reverse air cleaning cycle
A cleaning carriage moves from row to row. Above the cleaning air radial fan, a valve pulses air through a telescopic pipe, inflating each bag and reversing the flow to release the dust cake without compressed air.

Dust discharge
Dust is discharged from the hopper and screw conveyor by a rotary valve. Conveying systems or big bags can be connected below the rotary valve.
