Where to buy Donaldson Dalamatic Dust Collectors and Filters

Posted

The Donaldson Dalamatic dust collectors are extremely versatile units that can be utilized on many different types of applications. The key to the Dalamatic dust collector design is the Dura Life envelope shape insertable filter. This filter, when pulsing during the cleaning cycle, moves in a wave design that creates a ‘pop’ that dislodges the dust cake on the surface of the filters for the greatest cleaning efficiency for tough dust applications. The superior filter life and cleaning efficiency of these systems allows the DCE Dalamatic dust collector to be used in applications such as bins, silos, bunkers, storage vessels or transfer points. Industries in which these units are most widely used are cement and minerals, chemicals, plastics, food processing, foundries, metalworking and pharmaceutical. Due to the versatile design of these units, the dust collection solution on many custom applications is the Dalamatic Cased or DalamaticInsertable units. Contact PCS today to determine if the Dalamatic unit is best for your applications. A PCS engineer would be happy to discuss your process and size a dust collector to suit your needs.

Dalamatic Cased Dust Collectors- DLMC

  • Envelope-shaped bags provide maximum filter area per given space and ensure efficient cleaning.
  • Air volumes range from 1500 to 85,000 cfm.
  • Modular design gives dimensional and capacity flexibility.
  • Downward airflow pattern minimizes dust reentrainment.
  • Side doors provide easy, clean side access to filters.
  • Standard leg pack meets IBC 2003 requirements.

DalamaticInsertable Dust Collectors – DLMV

  • Five configurations to suit most process applications
  • Uses positive pressure of the conveying air or can be fan powered for pneumatic conveying applications
  • Bags can be installed hanging vertically, horizontally or any angle in between
  • Can be inserted into hood enclosures at belt transfer points, bucket elevator casings, ribbon blenders and receiving hoppers for clamshell unloaders
  • Insertable approach reduces or eliminates ducting costs; minimized ducting can also result in reduced energy costs

Operation Explanation

Normal Operation: Dust-laden air is ducted into the dirty air plenum containing the filter elements, where it collects on the outer surfaces. A layer of dust builds up on the outside of the elements as the air itself penetrates the fabric. The clean air emerges from the outlet header of each filter element into the clean air chamber and from there is discharged, normally via the fan, into the atmosphere.

Filter Cleaning: At regular intervals, governed by the controller, each element in turn receives a short burst of compressed air from its respective jet tube (blow pipe). The jet tube has a series of small-diameter jet orifices positioned adjacent to the outlet header of each filter element.

These orifices are of an optimum size and distance from the filter element, ensuring that a large volume of ambient air is induced by each injection of compressed air. This causes a brief, powerful reversal of airflow through the filter element, flexing the fabric outwards and effectively dislodging the dust layer which then falls into the discharge hopper.

In this way, the pressure drop across the entire collector is kept at a virtually constant level, enabling the Dalamatic to operate continuously, twenty-four hours a day.

Top-Quality Dalamatic Cased Dust Collection Systems

The Dalamatic Cased collector is designed to handle a broad range of dust and airflows while delivering reliable efficiency and extended filter life. It is suitable for both nuisance dust control and process dust control. The Dalamatic cased filter with envelope shaped filter bags is an alternate to the round bag pulse jet filter and has significant advantages in applications involving light density dust, free flowing non-agglomerating dust, fibrous dust, explosive dust, and installations where low headroom and floor space are a concern.
