AeroPulse baghouses for the asphalt industry
meet air pollution codes with a dust collector that:

Less expensive to buy
The initial cost of any baghouse is a function of the square feet of filter cloth required to remove particulate while allowing the baghouse to operate at an acceptable pressure drop. Dividing the gas flow through the baghouse by the square feet of filter cloth gives you the air-to-cloth ratio, a basic parameter of baghouse design. A baghouse that can operate at a higher air-to-cloth ratio will require fewer bags to provide the same performance.

AeroPulse baghouses cost less to acquire because they are more efficient. They will operate at a higher air-to-cloth ratio than any other baghouse. We are able to achieve these higher ratios because of fundamental differences in the bag material we use and in the design of the baghouse itself.

The AeroFelt™ bags used in our dust collectors feature a unique construction that combines fibers of varying thicknesses. This construction gives you more efficient filtration. The increased triboelectric properties of AeroFelt™ material results in the ability of the bag to handle more CFM of air per square foot of cloth.

Less expensive to operate
With AeroPulse’s smaller bags, less compressed air is needed to clean the bags. While a 4 1/2" bag has about 75% of the surface area of a 6" bag, it has only about 50% of the volume so less compressed air is needed to create the same cleaning pressure. AeroPulse bags use about 1/3 less compressed air than the larger bags. And, compressed air is expensive, so it’s easy to see why AeroPulse baghouses cost significantly less to operate.

Less expensive to maintain
During cleaning, a short burst, or pulse, of clean air is injected into the top of the bag. With an AeroPulse baghouse, this pulse consists of 20-25% compressed air and 75-80% clean process gas. This high ratio of process gas results in less temperature drop during cleaning, and less moisture condensation, significantly increasing bag life.

The venturi in an AeroPulse baghouse has lugs that lock under the tubesheet, providing high lateral stability and less chance of bag wear. And, since there is more open space between bags, there is even less likelihood of bags rubbing against each other.

With an AeroPulse baghouse, bag, cage and venturi are removed as a complete unit with a single quarter-turn of the "taper-lock" venturi, no one ever has to enter the baghouse to change bags.

In summary, AeroPulse bags last longer. And when they do need to be replaced, the higher air-to-cloth ratio saves you money again.

Proven performance in the asphalt industryAeroPulse has been a leading supplier to the asphalt industry for over 35 years. We have designed and installed over 200 baghouses in hot mix applications, some of which are still in operation after 35 years. This installed base provides us with extensive data on long term performance in these applications.

When a baghouse can’t handle the required airflow, it directly affects your productivity. With millions of dollars of road building equipment and crews of twenty or more at the job site, the inability to lay down the optimum tonnage can cost you hundreds of dollars per hour. Don’t rely on conventional wisdom about the air-to-cloth ratio you need. Find out about the baghouse that will keep your plant running and still:
