The high performance Downflo Oval 1 (DFO) family of over-achieving dust collectors is the best value available. Providing up to 25% more filtration capacity than same-sized cartridge collectors, DFO adds up to long-term savings and better performance.

The DFO advantage is found in the collector's patented design and components proprietary, ultra-efficient filter media and cleaning technology allow more airflow through the collector without increasing the size of the footprint or damaging the filters.

A smaller collector helps lower the initial purchase price, reduces filter replacement costs and opens up valuable manufacturing floor space.

Ultra-Web Nanofiber Media

A dramatic departure from traditional circular-shaped cartridge filters, DFO's oval-shaped filters, in conjunction with their patented nanofiber filter media, trap more dust on the surface of the filter than conventional commodity types of filter media such as depth-loading cellulose, polyester or cellulose/polyester blend.

DFO Filter Media Pleats

Shorter and stiffer filter pleats help minimize dust entrapment and simplify filter cleaning. By reducing the height of filter pleats from the standard 2 inches to 1.5 inches, the pleat wall is less likely to collapse or bend, which can encapsulate dust and prevent its expulsion.

Pulse Cleaning Technology

ExtraLife Filter Cleaning System uses proprietary computer-modeled pulse cleaning technology to easily "pulse off" dust from the surface of the filter, improving filtration efficiency and prolonging filter life. The red lines in the illustration show the increased pressure at the front of the Downflo filter generated by the ExtraLife system. The blue line shows the pulse signature of a standard cartridge collector.

Easy Maintenance

With the new design of DFO's quick-release access handles, filter removal and maintenance is extremely fast with one simple movement of the clamp.
