Efficient Extraction for Industrial Applications

The BOFA DustPRO 400 (DP400 / DP-400, model D0944A) is engineered for the effective removal of dust, swarf, and fine particulate generated during more demanding industrial processes.

Typical applications include:

  • Drilling and production machining

  • CNC routing

  • Mechanical engraving

  • Grinding and turning

  • General engineering and manufacturing operations

With over double the airflow of the DustPRO 250, the DP400 is designed for environments where higher dust volumes, longer run times, or multiple operators require consistent extraction performance.

Who is the DustPRO 400 for?

The DustPRO 400 is best suited to:

  • Medium to heavy-duty industrial applications

  • Single or dual-user workstations

  • Workshops requiring continuous extraction operation

  • Processes generating higher dust volumes than DP250

  • Engineering, manufacturing, and production environments

If your application involves combustible dust (e.g. aluminium or titanium), the DustPRO 400 is not suitable — in these cases, the DustPRO 1000 iQ with Spark Arrestor 2 should be used.

Key Features & Benefits of The DustPRO 400

Dual-Stage Filtration

HEPA Filtration (99.995% Efficiency)

The integrated HEPA filter removes 99.995% of particles at 0.3 microns, ensuring effective capture of fine airborne dust in industrial environments.

This helps provide:

  • Cleaner air returned to the workspace

  • Reduced airborne contamination

  • Improved operator safety

  • Support for dust control compliance

6.4 L Bag Pre-Filter

A 6.4-litre filter bag captures larger particles before they reach the HEPA filter.

Benefits include:

  • Extended HEPA filter lifespan

  • Reduced maintenance frequency

  • Lower long-term running costs

  • More consistent extraction performance

Brushless High-Vacuum Pump

The DustPRO 400 uses a brushless high-vacuum blower, designed for continuous industrial operation.

Key advantages:

  • Continuous running capability

  • Reduced maintenance vs brushed motors

  • Long service life (significantly extended operating hours)

  • Stable, consistent suction performance

Adjustable Airflow & Smart Control

The DP400 includes variable airflow speed control, allowing users to match extraction performance to the application.

Additional benefits:

  • Optimised energy usage

  • Greater control over extraction intensity

  • Flexibility across different processes

The unit also features multi-voltage sensing, automatically adapting to local power supply.

Compact & Workshop-Friendly Design

Despite its increased performance, the DustPRO 400 maintains a compact footprint:

  • 600 × 285 × 275 mm cabinet size

  • Low noise level (<66 dBA)

  • Durable powder-coated steel construction

This makes it suitable for integration into busy workshop environments without excessive space or noise impact.

Optional Extras

To enhance functionality, improve efficiency, and support integration into industrial workflows, the BOFA DustPRO 400 (DP400 / DP-400) can be configured with the following optional features:

Remote Stop/Start Signal (Optional)

The remote stop/start signal allows the DustPRO 400 to automatically operate in sync with your machinery.

This means the extraction unit only runs when your equipment is active, helping to:

  • Reduce unnecessary energy consumption

  • Lower operating and running costs

  • Extend filter life and system longevity

  • Improve overall process efficiency

This feature enables the extractor to be controlled via an external signal, allowing seamless integration into automated or production-based environments.

Filter Change Signal (Optional)

The filter change signal provides a clear alert when filters become full or require replacement.

This helps ensure:

  • Consistent airflow and extraction performance

  • Reduced risk of system inefficiency or blockage

  • Timely maintenance and servicing

  • Protection of internal components

The system monitors filter condition and alerts the operator when maintenance is required, helping prevent performance drop-off and unplanned downtime.

ideal Applications

Following our BOFA Workplace Extraction Flow Chart, the DustPRO 400 is recommended where:

  • Dust volumes exceed light-duty levels

  • One or two operators require extraction

  • Continuous operation is required

  • Higher airflow than the DP250 is needed

  • Dust is non-combustible

This makes the DustPRO400 particularly suitable for:

  • Engineering workshops

  • Manufacturing environments

  • CNC routing stations

  • Production grinding and machining areas

If working with combustible metals or AM materials, refer to the DustPRO 1000 iQ and Spark Arrestor 2.

Replacement Filters

The BOFA DustPRO 400 (DP400 / DP-400) uses a dual-stage filtration system consisting of a filter bag (pre-filter) and HEPA filter.

For optimal performance, filters should be checked regularly and replaced when airflow or extraction efficiency begins to drop.

These filters are specifically designed for use with both the DustPRO 250 and DustPRO 400 systems.

Replacing both filters together helps:

  • Maintain consistent airflow performance

  • Ensure effective fine particulate capture

  • Protect internal components

  • Extend the working life of the unit

The DustPRO 400 delivers up to 400 m³/hr airflow at 96 mbar pressure, providing significantly higher extraction performance than the DustPRO 250.

This makes it suitable for higher dust volumes and multi-user applications.

  • DP400/1 → Single extraction port (1 user)

  • DP400/2 → Dual extraction ports (2 users)

The DP400/2 allows simultaneous extraction from two workstations, making it ideal for shared or production environments.

The DustPRO 400 uses a dual-stage filtration system:

  • Filter bag (pre-filter) for larger particles

  • HEPA filter capturing 99.995% of particles at 0.3 microns

This ensures both effective particulate capture and clean air recirculation.

Yes. The unit features a brushless high-vacuum blower, designed for continuous industrial use with reduced wear and longer lifespan.

Filter replacement depends on usage and dust load, but typically:

  • Replace when airflow performance drops

  • Replace when the system indicates filter blockage

  • Typically every 6–12 months in regular use

 

Regular maintenance helps maintain performance and extend system life.

The DustPRO 400 uses:

Both filters should be used together for optimal filtration performance.

Yes. The DustPRO 400 requires the BOFA-KIT1 hose system for operation.

  • DP400/1 → requires 1 hose kit

  • DP400/2 → requires 2 hose kits (one per port)

Yes. The DustPRO 400 is designed for higher dust volumes and heavier-duty applications than the DustPRO 250.

However, it is still intended for non-combustible dust only.

No. The DustPRO 400 is not suitable for combustible or explosive dusts.

For these applications, a system such as the DustPRO 1000 iQ with Spark Arrestor should be used, along with appropriate safety measures.

No. The unit operates at less than 66 dBA, making it suitable for most workshop and production environments.

No. Thanks to its high-efficiency HEPA filtration, the DustPRO 400 safely returns filtered air back into the workspace, eliminating the need for external ducting in most applications.
