This type of air cleaning solution, also known as reverse pulse, is a method or air cleaning referring to the rhythm of the air cleaner’s cleaning frequency. The filter is cleaned by an immediate burst of compressed air injected against the flow of the dust air stream through the filter media. During regular dust collection, the contaminated air flows through the filter where large dust contaminants are trapped on the filter’s surface. Once a thick layer of dust collection is built on the filter’s surface, known as a dust cake or a filter cake; this is when the quick burst of air is shot though the filter in the dust streams opposing direction breaking up the dust cake making the dust particles fall into the collection bin.

Some reverse jet dust collectors must halt it’s ventilation cycle in order to clean its filter while some other systems can pulse clean while continuing it’s cleaning cycle. Originally used with fabric filter bags, later jet dust collector technology adapted itself to cleaning cartridges.

There are a various types of continuous jet dust collector systems which include:

The portable reverse jet dust collectors which a utilize a cartridge system housed in a refrigerator like unit that can be moved around different locations in your work area; with a intake arm which can be positioned over your specific work area. The advantage of this is workers can have serious dust collection to any part of their studio by simply rolling the unit from work area to work area.

Another type of jet dust collecting unit is the stationary intermittent duty cartridge collector. This type of pulse dust collection provides effective dust filtration usually housed in a stationary one or two cartridge unit with flexible dust intake arms. One unit can can provide dust collection for multiple workstations at once. As the name implies “intermittent”, the unit is designed for workstations that are not on a continuous on cycle.

A modular cartridge dust collector are numerous rows of cartridge filters that can be attached adjacent to each other providing a work area limitless amount of filtration. Each unit is specifically designed for the needs of the facility and are heavy duty units which provide work areas and production facilities with proper dust collection. The more units are attached the larger and nosier the unit. For space and noise concerns some facilities install the large multi-units of cartridge dust collectors outside while properly connecting air ducts within the facility to provide the whole establishment with ample dust collection.

Fabric jet dust collectors have improved since the initial limitations of original fabric collectors. The latest dust collectors are built to be able to handle high pressure temperature in corrosive conditions. Fabric collectors are tube like bags connected by an intake hole at the top where a continuous stream of compressed air is blown into the top. Compressed air jet holes are installed at the throat of each bag. Once the compressed air continuously starts and stops the bag expands and contracts breaking up the dust cake and cleaning the area during the cycle.
