The Modu-Kleen® Series 669 Bin Vent Filter from Dynamic Air is an innovative design, which solves the many problems plaguing conventional bin vent filters. Each filter is totally independent and can be easily removed without having to enter any kind of filter housing, which can resolve the EU OSHA Confined Space Hazard issue. Plus, maintenance and troubleshooting are quick and easy. This also makes maintenance much safer when trying to filter hazardous or toxic materials. Other important and dramatic features of the Modu-Kleen 669 bin vent filter are its small size and modular nature. It is adaptable to almost any application where space is a concern, and additional filter area can be easily added at a nominal cost, if required. Installation costs are also much lower, because the Modu-Kleen Series 669 bin vent filter is so much smaller and lighter than conventional bin vent filters. This makes it easy to install by hand, without the need for any special tools or heavy equipment to lift it into place. Pressure differential and automatic self-cleaning controls are standard.
