Comparison of FS – FD Filtration Systems (Dantherm / Nederman Type)
Industrial filtration plays a crucial role in reducing airborne particulate emissions and improving environmental quality.
The FS and FD filtration systems are two effective technologies used in heavy and chemical industries.
These systems were initially developed by Dantherm and later by Nederman.
Nederman FS Type System: Reverse Air Cleaning
The FS system utilizes a reverse air cleaning mechanism generated by a fan.
It operates at low pressure, ensuring effective cleaning while optimizing the life time of filter bags.
Key Features:
Reverse air filtration: Clean air is injected reverse flow to clean the filter bags.
Filter bag set up: Bags are arranged horizontally to optimize space and efficiency.
Low energy consumption: Reverse air uses lower pressure, reducing operating costs.
Gravity-driven dust removal: Dust enters from the top and falls naturally, preventing reverse flow issues.
Advantages of FS:
Simplified maintenance: The smooth cleaning system preserves filter bags.
Ideal for applications with low dust loads.
Lower energy consumption compared to other systems.
Compact and modular filter design, low foot print
FS Technical Data:
📌 Filtration surface: up to 2500 m² in a single unit.
📌 Operating temperature: up to 220°C.
📌 Applications: aluminum production, foundries, asphalt, quarries, mineral industries.
The FD system uses compressed air pulses to efficiently clean accumulated dust from filter bags.
Key Features:
Pulse jet cleaning system: Filter bags are cleaned by pulse jet of pressurized air.
Compact filter bag arrangement: Optimized structure for maximum efficiency.
High dust load capacity: Designed to handle large volumes of particulates.
Advantages of FD:
High-efficiency filtration for applications with heavy dust loads.
Faster and more effective cleaning due to compressed air pulses.
Ideal for heavy industries handling large particulate volumes.
Gravity-driven dust removal: Dust enters from the top and falls naturally, avoiding reverse air.
FD Technical Data:
📌 Filtration surface: up to 1100 m² in a single unit.
📌 Operating temperature: up to 250°C.
📌 Compressed air consumption: ranges from 8 to 52 Nm³/h, depending on filter size.
📌 Structure: Robust welded steel, modular design for a compact footprint.
