A second hand DCE Unimaster UMA 252 G5 dust extraction unit designed to stand alongside a very wide range of dust generating machinery and processes. The Unimaster UMA 252 is a compact, self contained fabric filter dust control unit complete with 3kW // 4Hp fan, self cleaning mechanism,  explosion relief panel, easy-access filter assembly and a 2ft³ waste container bucket with quick-release sealer gear and bucket balance facility.

Design features

  • Compact Design to minimise floor space and fits in virtually any plant layout.
  • Versatile to suit a variety of dust collection applications.
  • Quiet & Efficient Operation, motors and fan are enclosed in collector housing to minimise noise.
  • 2ft³ collection bucket
  • Bucket balance allows plastic collection bags to be used within the collection buckets by equalising the pressure behind the bag and preventing it from being sucked upwards.
  • Explosion relief panel allows the unit to be safely used with potentially explosive dust and gases, such as those generated like aluminium and flour dust in an air enriched environment.
  • Silencer box reduces noise levels in the environment.
  • Quick-Release lever allows for easy removal and maintenance of bin.#
  • Inlet deflector knocks down larger particles into the hopper reducing bag abrasion and increasing bag filter life.
  • Heavy-duty flexible metal inner bag coils inserted into filter bags keeps bags open to maximize airflow and assist in knocking the dust off during the cleaning cycle.
  • Bag-Release Screw allows for easy removal of bags.
  • Manual start shaker cycle to remove collected dust from the filter bags into the collection hopper.

How do Dust Extractors Work?

Dust collection systems work in a variety of different ways but all have general principles in common. They draw process dust and particulates from the air through a filter that first captures and separates the matter, and then discharges decontaminated air back into the workplace or environment.

Dust extractors are used in many different and varied industries and so different demands are made of them; however all have common components such as a blower (or fan), dust filter, filter cleaning system, dust container and dust removal system.

Five common types of dust collection equipment are fabric filter baghouses, inertial separators (like mechanical cyclones), cartridge collectors, wet scrubbers, and electrostatic precipitators.

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 Shaker Dust Collectors?

Shaker Dust Collectors contain a number of woven bags, which are fixed onto rails and use their surface area to capture dust as it is drawn through the extraction unit by its fan.

Bags are periodically cleaned by rapidly shaking the bags through a shaker motor and linkage system which removes the filtered dust from the bags and into a collection bin.

These units are commonly used in foundries, steel mills, the mining industry, power plants, and smelting industries.
