ACCORDION FILTERS are used in spray finishing booths the world over.

THE INVENTION

“Accordion-style, pleated paper” overspray collection filters were the brainstorm of inventor Erhard Andreae some fifty years ago.  Erhard sold his invention to a booth manufacturer who, in turn, was purchased by Binks.  At that time, Binks was the number one booth manufacturer in the world.  Their acquisition put Andreae Filters in spray booths worldwide.   

OPPORTUNITY KNOCKS

As patents expired, other manufacturers began to produce accordion-style paint arrestors.  Some redesigned the filter to change the backing and others redesigned the machine to handle varying widths.  But when Andreae Team decided to close the US factory and move to Canada in 2016, AFX took the opportunity to redesign the machine to build a better baffle.

THE FUTURE

AFX Manufacturing is proud to join only a handful of manufacturers to produce accordion-style spray booth exhaust filters.  The Accordion paint baffle is now produced by the first and only American owned and operated manufacturer of accordion filters.
