Reverse Pulsejet Baghouse Dust Collectors



Dynavac® Reverse Pulse Jet Bag House Dust Collectors are built tough to work in the most difficult factory environments. Our Bag type dust collectors come equipped with an automatic cleaning system which jets of compressed to clean the bag filter. Bag house industrial dust collectors are the largest dust collectors available in the market and are the preferred designs in locations where large quantities of dust are produced. Some of the options available for bag house dust collector systems are explosion proof, anti-static, food grade, stainless steel, etc. Bag House Dust Collectors are also sometimes referred to as Bag Filters


In a Bag house type filter dust collector system with automatic cleaning, individual filter bags are overlaid on a metal cage. The dirty air enters the Bag house and is forced through the filter bags after which the clean air exits.

A timer signals a solenoid valve to start the cleaning when it detects a drop in performance due to build up on the filter or the cleaning cycle is run on a regular periodic basis. Cleaning the filter is done by short bursts of compressed air being fired down through the filter bags. This air burst causes the dust cake to disintegrate and fall so it can be collected. This kind of cleaning using‘Pulse Jet’ is more reliable and keeps the filter bags working efficiently.

The air-to-cloth ratiois the most important criteria for bag house filter design. It is calculated by dividing the amount of air entering by the total surface area of the filter. This ratio determines the volume of airflow through the dust collector. An optimal air to cloth ratio needs to be determined to find a balance between the size of the dust collector (capital costs) with the pressure drop (operating costs).

The differential pressure is a measure of the resistance to airflow in the system. Bag house filter dust collectors with a larger pressure drop require higher-powered fans to move air through the system, resulting in increased energy costs.

Determining the filter material is an important part of bag house design, as it determines the life and effectiveness of the filter bag. The type of fabric used depends on many factors including volume of dust, size of dust, moisture content etc.
