Dust extraction and air pollution control

Extraction and filter systems

Jet filter

Extraction and filter systems
Standard design with welded and profiled sheet steel construction and an efficiency ratio of 80% or above.
Constructed to cope with volume flows of 100,000 m3/h for a single inlet and an overall pressure increase of up to 200,000 Pa.
The model series and drive system are determined by the operational conditions (e.g. amount of material, dust content, temperature range, volume flow, overall pressure increase).
Each individual series differs in terms of its aerodynamic properties such as diameter ratio, blade formation and number of blades, rotor width, housing shape, etc., type of construction and performance ranges.
The specification of the specific sound power levels for each of the various fan sizes complies with DIN 45635.

Filter systems
Scope of application
per unit up to 500,000 m3/h.
Our innovative work and many years of experience means we are able to offer our customers a comprehensive range of different filter systems to meet each individual need.

Filter with pulsed compressed air cleaning

Jet filter

Filter with pulsed compressed air cleaning
Jet filters are fitted on a panel system according to a shock pressure resistant design.
The following discharge devices are used:
discharge screws / barrel core dischargers / push rod dischargers.
The discharge devices are adjusted according to the raw material being filtered.
In this system, the fans may be assembled on either the raw gas side or the clean gas side.
Alternatives: jet serial filter / jet dedusting filter / jet compact filter
