Description

The Unimaster style dust collector is an economical and effective solution suitable for a wide range of applications including abrasive blasting, polishing and buffing, grinding, packing of tea or detergents, weighing and mixing of paint pigments, food processing applications and a host of other operations where nuisance dust is generated.

The dust collector reduces airborne contaminants from the working environment, helps improve air quality for your employees and product quality for your customers. Effective dust control is guaranteed with this compact pulse jet dust collector.

Main features:

  • Dust capture at all manufacturing points and flexibility of operation.
  • Secondary Filter (HEPA).
  • Compact design with cartridge filters.
  • 3 off cartridge filters with pulse jet cleaning.
  • Advanced 2.0kW // 2.7Hp  ATEX compliant fan design with reduced noise levels.
  • Up-scoop with ATEX rated explosion relief panel.
  • Sound reducing hood.
  • Easy to install/connect and service.
  • No requirements for compressed air.

Versatility and dust capture at all points

Highly adaptable, the dust collector is ideal for intermittent operations in plant processes. Several space-saving units can be placed at dust generation points resulting in total dust capture from the manufacturing processes:

Efficient filtration operation with cost-effective self-cleaning cycle

Utilising high performance cartridge filters, contaminated air is drawn in through the inlet to the filter by the fan. Initially, some pre-separation takes place as heavier dust particles lose momentum and fall into the hopper.

Finer dusts are carried up to the filter elements and retained on the outer surface of the filter fabric. The cleaned air passes through the filter fabric into the fan chamber and is discharged. At the end of the process or of a shift the fan is switched off and the filter fabric cleaning cycle commences: Dust is dislodged from the filter elements and falls into the collector. This cleaning cycle requires no compressed air, reducing the services required and operating costs.

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.

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 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. 

What are Cartridge Dust Collectors?

Cartridge Dust Collectors a type of filter unit which is predominantly used in environments where space is at a premium. They can often maintain airflows which remain comparable to larger baghouse units.

Cartridge units provide larger fabric filter areas into a smaller place, use less filters and can be changed from the outside of the extractor, rather than having to access the unit internally, thus reducing filter replacement times and less environmental contamination issues for maintenance staff.

They are ideal for commercial and industrial environments, whose processes produce very fine-to- moderate dust-like powders, metalworking, woodworking, fume collection, thermal spraying, among other processes.
