Description

This Heaton Green Econojet dust extractor is a compact, versatile dust collector designed to efficiently separate solid particles from dust laden air. Featuring a flat pad filters and automatic reverse pulse cleaning, it provides reliable dust control across a wide range of industrial applications, from silo venting to larger dust extraction systems.

Operation

Dust laden air passes through the flat-pad filter elements, where solid particles are captured and clean air passes into the filtered air section. An automatic reverse jet cleaning system uses short bursts of compressed air to dislodge accumulated dust from the filters, helping maintain airflow and consistent filtration performance during operation.

A sequential controller cycles through the filter rows in turn, allowing cleaning to take place with minimal disruption to filtration. Durable filter seals help maintain separation between the clean and dirty air sections, while the automatic cleaning system reduces the need for manual intervention.

Reverse Pulse Jet System 

The Econojet uses a reverse jet system, controlled by a sequential controller, to automatically clean its filter bags and maintain airflow.

  • Dust Collection - Dust laden air enters the filter and is met by the collection surface of the media, where it is arrested. There is a resultant buildup of dust forming a ‘cake’, increasing pressure drop and restricting air flow.
  • Controller Operation - Once activated the controller will begin its cleaning cycle. Each row of filters will be cleaned in sequence on a continuous basis resulting in a regular pressure drop and airflow.
  • Pulse Cleaning - A solenoid valve releases a short burst of compressed air from the manifold. Air enters the filter bag from the clean side, creating a reverse pulse of air.
  • Dust Release - The effect on the filter element is to rapidly expand and ‘snap’ back onto the support cage breaking the dust cake and depositing it out of the airstream.
  • Sequential Cycle - The controller works to clean one row of filters at a time, continuously and automatically. This prevents blockage and reduces the need for manual cleaning and system downtime.

Specification

  • Temperature range: -20 +80

Importance of Dust Extractors

Dust in the workplace can affect product quality and employee´s health. Having a dust-free environment is essential to the health and safety of the workforce. Not only does it affect the health of employees but the dust covers the equipment affecting production processes and quality of the products. 

Capturing the dust at the source prevents it from spreading, done by using a dust extractor system to facilitate the important housekeeping to avoid it from accumulating.

What are Reverse Pulse Jet Dust Collectors?

Reverse Pulse Jet Dust Collectors use a jet of air to clean dust from the collector's filters. Commonly used in pleated filter cartridge units, the filters are cleaned by a series of rapid, high-pressure air jets which sends a blast or shock of air through the reverse side of the filters. In effect this shakes the collected dust from the filters into the dust collection system. The rapid reverse pulse of air allows for continuous operation with the fan running and has high collection efficiencies.

Reverse Pulse Jet Dust Collectors are the most common type of industrial dust collectors and can handle a wide range of temperatures and pressures. They are commonly used in manufacturing environments where large volumes of solids are processed, such as mineral production, food processing and metal fabrication industries.

A control unit sets the variables such as time duration between pulses, length of pulse and pressure.
