SPÄNEX GmbH

The extensive product range of compact dust extractors manufactured by SPÄNEX covers the air performance range between 1,200 and 10,000 m³/h. The decisive advantage of dust extractors is due to the fact that they can be installed directly in the working area and thus organic dusts of dust explosion class St1 can be extracted and filtered.

By combining several dust extractors (battery installation), the range of application can be extended to an extraction air volume of up to 40,000 m³/h (four dust extractors) and applications can be served where an outdoor installation of industrial filter systems as required by standards (DIN EN 12779) is not possible for structural reasons.

Plus points of the dust extractor series:

• Installation in the working space without explosion relief devices
• Extremely compact design
• High suction power
• Return air operation (residual dust concentration < 0.1 mg/m³)
• Chip/dust disposal by means of integrated collection bins, pneumatic conveying systems (into silos or containers) or direct briquetting by means of under-mounted presses
• Quiet, energy-saving operation
• Complete circuitry
• Easy handling
• Tested by the BGHM - Employer's Liability Insurance Association - (DGUV test certificate H3, GS test mark).

Briquetting brings tangible advantages!

Machining processes produce residues in the form of chips, dusts and wood chips that are recycled, used for energy or disposed of. For each of the fields of application, briquetting is an alternative solution that offers tangible advantages:

• Volume reduction
• Material-related: up to 95 %,
• Bulk behaviour-related: up to 50 %,
• Improved handling of residual materials,
• Production of saleable wood briquettes,
• Reduction of the risk of fire and explosion due to particulate matter,
• No time-consuming material preparation required.

The following materials can be briquetted:

• Wood,
• Plastic,
• Aluminium and other easy-weight metals,
• Paper,
• Tobacco,
• Rice husks,
• Biomass.

Industrial filter systems are the core component of any extraction system. Based on the extraction air quantity, SPÄNEX industrial filter units can be divided into three categories:

• Dust extractors
• Compact filter systems
• Large filter systems

Compact filter systems

Industrial compact filter systems are part of extraction systems in the air volume range between 10,000 and 50,000 m³/h. The modular filter system can be individually adapted to any requirement and convinces by high performance with smallest space demand.

The large filter program consists of three series:

Battery filter systems
The battery filters are assembled from the units of the compact filter program and are particularly interesting for applications that require an extraction air volume between 50,000 and 100,000 m³/h.

Line filter systems  
The line filters offer the advantage of expandability, i.e. the filter system can grow with the production. The application range usually starts at air volumes from 80,000 m³/h and reaches up to 200,000 m³/h.

Filter houses
Filter houses are compact industrial filter systems with a square base and a large container volume. Due to their buffering capacity, fluctuations in the amount of separated chips and dust can be compensated and the transport system can be operated intermittently.

The filter media and the cleaning system are adapted depending on the task.

Advantages of the SPÄNEX industrial filter systems:

• Modular system - optimum adaptation to requirements
• CAD project planning linked to CNC-supported production systems
• Extraction fan can be installed in the filter housing
• with or without pre-separation chamber
• Vibration, compressed air and reverse air cleaning
• negative or positive pressure technology
• Continuous or discontinuous operation
• Return air operation (residual dust concentration < 0.1 mg/m³).

SPÄNEX offers innovative and economical system technology for the extraction of the overspray produced during painting and for the supply of the inlet air for a wide range of applications.

For larger air volumes, the highest value is placed on the energy efficiency of the system. With the help of heat recovery, the thermal power requirement is reduced. Intelligent control technology ensures constant working conditions through speed-controlled drive of the extract and inlet air fans.

Today, the inlet air units are usually equipped with a heat recovery system.

Our range of performance:

• Dry spray walls
• Underfloor extraction systems
• Combined systems
• Inlet air units with and without heat recovery
• Control and regulation technology
• Extraction tables and extraction walls for grinding work.
