Description

Compact and Versatile the Unimaster dust control unit is the most economical and effective solution for a diverse range of nuisance dust problems throughout the industry.

The Unimaster’s unrivalled quality and versatility mean that it is suitable for a multitude of applications. As a result, the Unimaster range is Donaldson's most universally accepted dust collector.

Industries of Application:

  • Chemical and Allied
  • Rubber and Plastic
  • Pharmaceutical
  • Lumber and Wood Products
  • Agricultural
  • Iron Foundries
  • Jewellery and Precious Metal 
  • Paint 
  • Stone, Clay and Glass
  • Metal Mining 
  • Food and Related Industries
  • Textile
  • Industrial Machines
  • Tobacco 

Principle of Operation

  • Contaminated air from the dust generation source is drawn through the inlet to the filter by a fan. Initially, some pre-separation takes place as heavier dust particles lose momentum and fall into the collection bin or hopper.
  • Finer dusts are carried to the filter elements where they are retained on the outer surface of the filter fabric. The cleaned air is then passed through the filter fabric and then through the secondary filter before being vented out of the unit.

Cleaning

  • When the filters need cleaning there is a manual lever which has to be operated to shake the filters and remove the dust. This is then dislodged from the filter elements and falls into the collection bin below.
  • The Unimaster is an ideal dust collector for intermittent operations in plant processes. Several small self-contained Unimaster units can be placed at the points of dust generation. This approach results in total dust capture and flexibility of operation.
  • A pressure differential gauge is fitted to indicate when cleaning of the filters is required.

Filtration Media for various applications such as:

  • Polyester
  • Polyester Anti static
  • Polyester Oleophobic
  • Polyester Oleophobic Antistatic
  • Tetratex
  • Tetratex Antistatic

Features Include:

  • 1.1kW 1.5Hp Fan set.
  • 415Volts, 3 phase, 50 Hz.
  • Multi positional inlet for easy connection to ducting and hoses.
  • Suitable for internal locations.

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.

Factors to Consider for Your Next Dust Extractor

When implementing the safety measures to ensure minimal risk to your workers, the factors to consider when purchasing your extraction unit/system are:

  • Dust Source - Does the process that produces dust occur in an enclosed or open area?
  • Capacity - Does the extractor have a large enough filter area required to handle the volume of dust?
  • Type of Dust – Do you need an extractor capable of handling dust at risk of self-igniting?
  • Maintenance – Would a self-cleaning extractor with an automatic shaker cycle be more suitable for you?

For further guidance, find out how to carry out your own COSHH (Control of Substances Hazardous to Health) risk assessment at the HSE website to help calculate your requirements.

What is Dry Dust Extraction?

The most popular dust extraction method, dry dust extractors collect dust using filters and cartridges. Known for processing large volumes of air when filtering medium/large dust particles such as wood, flour, and metals.

They typically include a cleaning system to discharge the dust gathered within the filters and cartridges, they carry out a shaker cycle or reverse pulse cycle to free the collected dust and empty it into a removable storage bin.
