A modular high-efficiency particulate air (HEPA) filtration system includes first and second modular filtration units and a blower unit. The blower unit draws air from an isolated indoor space of a facility via a ventilation input to maintain negative air pressure within the isolated indoor space. The first modular filtration unit and the second modular filtration unit are connected in parallel with the ventilation input and the blower unit. The first modular filtration unit is disposed between the blower unit and the ventilation input and at least a portion of air drawn through the ventilation input by the blower unit passes through the first modular filtration unit, and the second modular filtration unit is disposed between the blower unit and the ventilation input and at least a portion of the air drawn through the ventilation input by the blower unit passes through the second modular filtration unit.

An object of the present invention is to provide a dust collector including a pulse jet type dust removal mechanism capable of uniformly removing dust over the entire length of a cylindrical filter without increasing the pressure loss of the cylindrical filter; and a dust removal method for such a dust collector. The dust collector of the present invention is a dust collector including a pulse jet type dust removal mechanism for removing dust adhered to cylindrical filters, in which the pulse jet type dust removal mechanism includes: a first discharge section having first discharge nozzles for discharging pulse jets from first end side openings of the cylindrical filters toward inside of the cylindrical filters; and a second discharge section having second nozzles for discharging pulse jets from second end sides of the cylindrical filters toward openings on the first end side of the cylindrical filters, and the second nozzles for discharging are each provided on a tip side of a pipe line extending from the first end side to the second end side of the cylindrical filter.

A filtration system housing is provided for supporting filtration system components. The filtration system is configured to remove particulates from air. The housing comprises a plurality of walls defining a chamber for receiving pressurized air. The housing additionally comprises a reinforcing member at least partially surrounding said walls. At least one of the walls is contoured to include a spatial curvature extending along a portion of the at least one wall.

Included herein are filtration systems that can proactively pulse clean filter elements in response to anticipated changes, such as anticipated changes in filtration performance or anticipated changes in filtration system demand. In an embodiment, a filtration system is included having a filter element mount for a filter element, a compressed gas supply, and a valve, wherein opening the valve results in a pulse of gas directed at the filter element. A control circuit can control the valve. A communications circuit can receive data related to an anticipated change, such as data regarding an anticipated change in filtration performance and/or data regarding an anticipated change in filtration system demand. The control circuit can execute operations based on the anticipated change data such as adjusting a pressure drop threshold and initiating proactively opening the valve in the absence of a pressure drop threshold being crossed. Other embodiments are also included herein.
