Offline Effect
No carryover onto neighboring rows
Dust cake carryover from adjacent bag rows is prevented because neighboring rows stay offline while one row is being cleaned — protecting freshly cleaned bags from re-caking.
FS Baghouse dust collectors · industrial gas cleaning
Compact filtration, reverse air cleaning - for every breath
The Nederman MikroPul FS flat bag dust collector combines horizontally installed flat bags with intelligent reverse air cleaning technology — particularly suited to very fine dusts, metal vapors and harmful gases, high dust loads and high temperatures.
How it works
Down-flow 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.
Down-flow 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.
Why should you choose the FS
Flat Bag Filter
Dust Collector
The FS series dust collector with horizontally installed flat bag filters is a compact and efficient filter system with intelligent air cleaning technology. This system is ideal for high dust loads of finer dust particles and high gas temperatures. It is easy to install and transport to site, typically in a single container-sized flatbed delivery.
For industrial plant operators such as foundries, smelters, asphalt production and many others, the FS flat bag dust collector provides pollution control in a compact and easy-to-install package.
