Dust extractors SMU
SMU series
Dust extractors of the SMU series are used to extract dust from one or more processing machines. The extraction volume flows of our dust extractors range from 1,200 to 10,000 m³/h and are therefore the primary solution for joinery and carpentry workshops. However, they are also an ideal supplement to existing central extraction systems if the machine park is expands and the existing filter system does not have any reserve capacity.
By installing several dust extractors as a battery, maximum volume flows in the performance range of stationary filter systems can be achieved. 2 to 5 dust extractors installed in the workshop form the extraction centre, which provides air capacities of 20,000 to a maximum of 50,000 m³/h.
Areas of application
There are many possible applications. In terms of energy efficiency, decentralised extraction solutions with SMU dedusters can also have advantages compared to a central extraction system outside with long suction pipe routes. SMU dedusters, on the other hand,are installed close to the machine inside the workshop. When choosing a system, the individual aspects and factors must be weighed up in order to find the optimum system configuration for each individual case.
With dust extractors that have been tested by the BGHM and have received the DGUV test certificate (H3) and the GS mark for wood dust, chips and dust of various materials can be extracted and compacted, for example in combination with a briquetting press:
Wood
Plastic
Paper
Leather
Textile
Rubber
Aluminium
Brass
Other metals
The chips and dust must be dry and the KSt value must be ≤ 200 bar x m/s (dust explosion class St1). The KSt value is a technical explosion parameter that is determined within the scope of dust analyses.
Dust extractors SMU-B
Battery installation of dust extractors enables maximum extraction volume flows of up to 50,000 m³/h.

SPÄNEX-compact dust extractor
Up to 10,000 m³/h
The scope of application of dust extractors for the extraction of wood dust and chips is regulated in the European standard DIN EN 16770. Dust extractors that meet the requirements of the European standard may be installed directly in the working area when extracting organic dust, dust explosion class St1, due to their design. The advantages of extraction systems based on internally installed dust extractors are convincing:
Shorter suction pipe routes reduce investment and operating costs.
Complex return air duct systems are not required.
100 % heat recovery is achieved due to direct air recirculation.
The largely ready-to-use delivery leads to short installation times and thus low installation costs.
SPÄNEX dust extractors convince with high performance, best energy efficiency, quiet operation, compactness and ease of use.
Design
The dust extractors are delivered largely ready for operation and most of them are mobile, so that they can be easily brought into and set up in the working area. As standard, the dust extractors are supplied with 1 to 3 filling bins with inserted plastic bags. For the bigger dedusters (SMU 32 and above), the combination with a briquetting press is a frequently chosen variant.
The SHB 40/55 and SHB RS 55/70 briquetting presses have been especially designed to match the dust extractors. The machines are arranged directly underneath the SMU-container to save space.
For applications with very large quantities of chips, dust extractors with a container and attached rotary valve are available as a further design variant. The chips and dust collected in the container are transferred via a discharging device and the rotary valve to a screw or pneumatic conveyor system and conveyed to a container or silo outside.
Equipment variants
- Automatic start of the fan
- Automatic control of lock slides
- Operation via frequency converter
- Level monitoring in the containers with charging of briquette press or container and/or silo

Plus points
- Small footprint
- Low overall height
- High suction power
- Low power consumption
- Quiet operation
- Effective filter and cleaning technology
- No heat loss due to direct air recirculation
- Several disposal options
- Complete control system with automatic start-up
- Tested safety (GS and H3 test marks)
- Ease of operation
