HEPA filters are designed to filter 99.995% of particles as small as 0.3 microns. Secondary filter to remove fine particles.

Advanced carbon filters help capture contaminants and odors, reducing the risk of bypassing and tunneling. They are designed with special types of carbon tailored for industrial applications.

Reverse flow air technology reduces the speed and changes the direction of the air, causing larger particles to enter the filter outlet chamber. This reduces the ingress of particles into the filter media, significantly improving the filter's capture performance and extending the filter's life.

Automatic flow control allows the user to pre-set the correct airflow rates for a given application, helping to maintain airflow. This results in lower noise levels and helps protect the more expensive HEPA filters.

The system OK signal warns of an error when filters are blocked and when filters are approaching full capacity, allowing for efficient maintenance scheduling.

A remote stop/start signal ensures that your Donaldson BOFA fume extraction system only operates when your unit is running, helping to save on both operating costs and energy.

The VOC (Volatile Organic Compound) sensor continuously monitors exhaust air and alerts you if VOC levels exceed a preset threshold, preventing the release of unwanted VOCs and other unpleasant odors.
