GENERAL INFORMATION
The Airex Econopulse dust collector distinguishes itself not only by the superior efficiency found in its cyclonic effect but also by its simple construction design. In addition to allowing an effective cyclonic pre-separation, the Econopulse, being a downsized version of the Cyclopulse, is a very enviable solution from an economic point of view.
The system allows for a cyclonic pre-separation effect, limiting the particles to be filtered by its bag filtering system.
Its concept and characteristics meet the highest standard. The Econopulse dust collector ranks among the top available collectors for middle-range wood processing industry.
ADVANTAGES
- Unique bare bone and self-supported silo design
- Top access eliminates dirty side entry to change and service the bags
- Maximum filtration can be obtained through selection of certain items that include bag types, can velocity, collector shape and arrangement
- Steel internal cage supports are used to keep the bag form
- Snap-bands hold the bags in place
- No tools are required to remove the bags
- Standard cages and bags are easily available on the market
- Can operate at high temperatures up to 800˚F (special bags required)
- Large and heavy loading capacity
- Easily pulse cleans sticky and stringy materials
- Resists chemical products
- Resists humidity
- Stable pressure differential
- Energy recovery
- Maximum efficiency
- Adjustable pulse jet cycle
- NFPA Construction
THEORY OF OPERATION
HOW THE ECONOPULSE WORKS - PRINCIPAL FUNCTIONS
- The dust first travels toward the inside of the pre-separation via suction or positive pressure.
- The cyclonic effect drops the larger dust particles into the cone and anti-vortex for disposal.
- The remaining fine particles flow toward the media filtering module and are captured on the exterior surface of the filter bags.
- Air is filtered and recirculated (compressed air) once the bags are cleaned by the jet system maintaining a constant differential pressure.

COMPRESSED AIR CLEANING SYSTEM
The dust particles accumulate on the exterior surface of the bags and at regular intervals a volume of compressed air is injected through the bags interior by a venturi tube that will induce a shock wave and provoke particles to fall toward the bottom of the hopper. Our self-cleaning system is built to reduce the consumption of compressed air by an optimum concept of nozzles and venturies.
