A centralized dust collection system for a furniture factory connects multiple woodworking machines to a shared network of hoods, ducts, a dust collector, and a fan. To select one, start with the machines that will operate together, their required extraction airflow, the duct layout, the type of dust, and the available space for the collector. The system should be engineered around those inputs rather than chosen by factory floor area alone. This guide explains the main design choices, purchasing considerations, and information to prepare before requesting a quotation from Lufmax.
This guide is for furniture manufacturers planning a new workshop, expanding production, replacing standalone extractors, or upgrading an existing industrial sawdust collection system. It is also relevant to buyers comparing suppliers and preparing a project brief. The right configuration depends on whether the factory processes solid wood, engineered panels, or a combination of materials, as well as how machines are scheduled. A site-specific review is important before ordering equipment.
Each machine is connected to a hood or extraction point, which captures dust and chips close to where they are produced. Branch ducts carry the material into a main duct and onward to a collector, where filtration separates dust from the conveying air. A fan provides the airflow needed to move material through the network, while collected dust is discharged into a suitable container or handling system. The cleaned air may be returned indoors or exhausted outside, depending on the design, site conditions, and applicable requirements.
Furniture factories commonly use a combination of ductwork, a fan, a filter collector, and dust discharge equipment. A cyclone or other pre-separation stage may be considered where the process produces substantial chips or heavier material, but the appropriate arrangement depends on the dust load and collector design. Filter options can include bag or cartridge configurations; neither is automatically best for every application. Evaluate filter media, cleaning method, access for replacement, and the characteristics of the material being collected.
Begin with a machine schedule that identifies each dust-producing machine, its extraction connection, and the manufacturer’s recommended airflow or connection information where available. Record which machines may run at the same time, their operating shifts, and whether production is expected to expand. A system sized only for the current average workload may not perform as intended when several high-demand machines operate together. Conversely, assuming every machine runs simultaneously can lead to an unnecessarily large proposal if that operating condition is not realistic.
Duct conveying velocity is one design consideration for keeping wood waste moving through the network. As an initial discussion point, designers may examine a conveying velocity around 18–22 m/s for wood dust, but the final target must be checked against the material, duct arrangement, machine requirements, and system design. It should not be treated as a universal specification. The supplier should calculate airflow and pressure requirements for the proposed layout.

For illustration only, a 400 mm diameter duct carrying air at 20 m/s corresponds to approximately 9,000 m³/h, based on the duct’s cross-sectional area. This calculation describes that example duct, not the required airflow for a particular factory or machine. Actual system airflow depends on the connected branches, open gates, hood design, pressure losses, and operating plan. Ask the supplier to show the assumptions behind the proposed airflow and fan selection.
| Specification | What to Clarify |
|---|---|
| Airflow | Required flow by machine and for the intended simultaneous operating condition, stated in m³/h. |
| Static pressure | Pressure available to overcome losses across the hoods, ducts, filters, and other components, stated in Pa. |
| Ductwork | Branch and main duct dimensions, routing, material, support, and provisions for balancing and access. |
| Filtration | Filter configuration, cleaning method, dust-handling arrangement, and service access. |
| Installation scope | Which equipment, ductwork, controls, electrical work, commissioning, and site services are included. |
The price of a centralized dust collection system is shaped by its airflow and pressure requirements, collector and fan selection, filter configuration, ductwork quantity, controls, and installation scope. Site conditions can also affect the design and logistics, particularly when the collector must fit within a restricted indoor or outdoor area. A reliable comparison therefore requires a defined scope and comparable assumptions from each supplier. A low equipment price may not represent the complete cost if ductwork, installation, or commissioning is excluded.
Minimum order quantities and lead times are supplier- and project-specific, so confirm them directly rather than relying on a general estimate. Request a written quotation that separates the equipment package from optional services and identifies the information still needed to finalize the design. If production timing is fixed, share the required delivery and installation windows early. This gives the supplier an opportunity to flag schedule constraints before order confirmation.
Before selecting a supplier, check whether its team can interpret your machine list and floor plan, explain the design assumptions, and identify missing project information. Ask how the supplier will support equipment selection, documentation, installation coordination, and maintenance questions. Confirm the boundaries between supplier work and local contractors, including who is responsible for site measurements, electrical connections, duct installation, and system start-up. Clear responsibilities help reduce avoidable changes during procurement and installation.
At Lufmax, we work with furniture factory buyers to review project requirements for centralized dust collection equipment. A useful first exchange includes your factory layout, machine list, operating schedule, material types, preferred collector location, and any known site constraints. With these details, we can discuss a configuration and clarify which design information needs confirmation before a quotation is finalized. Final equipment selection should be based on project-specific engineering review rather than a generic capacity estimate.
A centralized dust collection system is best selected by matching machine-level extraction needs with the operating schedule, duct network, filtration, and site conditions. Prepare a current floor plan, document which machines run together, and request a proposal that states its airflow, pressure, and scope assumptions. Treat preliminary figures as discussion points until a qualified design review confirms them. To discuss a furniture factory project with Lufmax, send your machine schedule and layout so we can help identify the next information needed for system selection.
