Cardboard Concertina Exhaust Filter

Andreae filters can hold more paint particles than other filters on the market and are used in industrial, aerospace, and metal fabrication applications. It is also known as the organ filter, gopher card, fluted card filter, painter's paper, and concertina, which are used in the liquid finishing industry worldwide.

Key Benefits

• The Andreae Exhaust Filter is an environmentally friendly filter built of cardboard pleats, giving it a wider surface area and a higher paint holding capacity. It has lower airflow resistance, allowing for high, uniformed airflow around the spray area.
• A concertina filter filters the air, preventing dangerous chemicals and particles from being inhaled by people within and outside the booth. This provides a safe working environment for employees and reduces critical health and safety risks.
• The cardboard filter is simple to install and lasts approximately 3-5 times longer than standard polyester or fibreglass filters.
• Resistant to moisture and has been treated with flame-retardant materials.
• Andreae Filters are the original and genuine cardboard filters, and they outperform the cheaper brands currently in use in Australia in many ways.

Key Features:

• The v-shaped front wall prevents overspray bounce back and particle migration.
• The deeper v-shape back wall captures overspray and deposits it outside the airflow.
• The filter exhaust holes are positioned to maintain constant airflow during the loading phase.
• Static pressure increases slowly with the accumulation of overspray resulting in
