Centralised extraction systems for wood dust are the industry standard solutions for medium to large sized workshops.
Centralised extraction systems for wood dust are the industry standard solution for medium to large sized workshops.
AES design, supply and install our own range of modular filter units and also supply and fully fit-out extraction units from some of the leading manufacturers.
C-VAC filter and fan unit with intelligent panel.
The C-VAC system is a high vacuum extraction system that has been designed for its ease of use; low noise characteristics and ability to both extract directly from machines and act as a centralised clean up system.
The unique C-VAC system is proven to provide a cleaner and safer working environment. It extracts wood dust from multiple machines simultaneously, incorporates plug-in points for portable tools and has attachments for cleaning dust from floor and benches. Designed for ease of use, it incorporates automatic valves linked to the wood working machines so that the extraction is on when required.
Dust is collected centrally in a sealable trolley-mounted bag for safe and easy disposal. C-VAC is powerful, yet quiet in operation.
Baghouse Filter Systems
Baghouse filter units containing cloth envelopes or tubes are the most common choice for the control of wood dust. These systems can have an integrated or standalone fan and can handle medium to large airflows. A variety of filter cleaning mechanisms are available to suit the dust type and usage including shakers, regeneration fans (reverse flow) and compressed air pulse.
An important consideration in the design of the system is the way dust will be collected for disposal. Options include discharge to bags or bins, or transfer into skips through closed loop fan systems or conveyors.
The section below provides further information on the types of discharge arrangement available.
Discharge to bag or bin
For small to medium amounts of waste, filter units that discharge waste directly into bins or bags can be the most economical solution. Each module can be fitted with either plastic/paper waste collection sacks or steel bins that are simple to change. Sensors can alert the user when the bins are full for ease of use.
Direct discharge to bulk bag or skip
For larger amounts of waste discharge into bags becomes impractical. An alternative solution is to discharge the waste directly into a skip or bulk bag through a rotary valve. Located at the bottom of the hopper on the dust filter, the rotary valve allows the waste to drop out while the system is running without pressure losses.
Units can be supported at height on a frame over the skip or bag which reduces the overall footprint – ideal where space is a premium. Look in our gallery of images below to see one of these installations in practise.
Discharge through transfer fan or conveyor
For large-scale production environments, discharge of waste into a large container may be the most cost-effective means of disposal.
The example in our gallery below shows the container placed adjacent to the dust extractor and the waste can either be blown into it through a closed loop with a transfer fan or by means of a chain or rotary conveyor.
Waste management and removal can be provided by a local environmental waste contractor or government agency, depending on the facility.
