Many users must create positive pressure in enclosures, rooms and buildings to keep out airborne contaminants such as dust, sand, and corrosive or dangerous gases. However, you often do not have clean air readily available that you can inject into the space to build up pressure. If you use filtration to clean the pressurizing air, you will encounter all the costs and complications of maintaining the filters.
Andover Protections Explosion proof ACBs having minimal requirements for maintenance enable users to pressurize their spaces at a comfortable level of maintenance and operating costs. As the ACBs blow air into the space being pressurized, they simultaneously remove the dust to provide clean air and pressurization. Since they throw the dust back into the atmosphere from which it comes rather than collecting it, there is no cartridge, bag or other media to clean or replace. Because explosion proof ACBs can work for months, or even years, with minimal servicing, they make it possible to pressurize containerized enclosures of all sizes, along with many places that have not been practical or cost-effective to pressurize in any other way.
