The importance of air filtration systems


In today’s industrial landscape, where safety and regulatory compliance are paramount, the choice of air filtration systems in vehicles becomes a critical decision.

To comply with the new international standard of air control systems (ISO 23875), the design, testing, operation, and maintenance of air quality control systems for heavy machinery is vital.

Whether combating silica dust, chemical fumes or noxious odours, the right air filtration system can mean the difference between a safe, healthy work environment and potential hazards.

Large volumes of hard and abrasive dust particles are typical in most mining and industrial processing related applications.

These particles rapidly wear out filter media, leading to frequent maintenance or worse: filter leaks. Without effective dust emission control, equipment, processes, employees, and the environment may be at risk, and production could be halted.

The following is a list of some typical areas generating dust that can be controlled by dust collection and/or mitigation equipment:

• Rail or truck dumps
• Crushers and/or screens
• Conveyor belt transfer points
• Silos or bin filling
• Earthworks
• Rail, barge, or truck loading

Helping to comply with ISO 23875 requirements, cabin pressurisation is designed to allow operators of equipment cabs or equipment in enclosures to “Breathe Easy” with clean air and to keep those cabs clean. Positive pressure is generated in the cab, pushing dirt out, preventing dust from coming in, and keeping the entire cab and HVAC system clean.

The Red Dot “CABAIRE System” incorporates an air pump, patented centrifugal air pre- cleaning, and options of filter media (Cellulose, HEPA, Activated Charcoal) to suit different working environments for above and below ground mining, processing, and distribution.

These systems offer a range of filtration options designed to address specific airborne contaminants effectively.

Among these, MERV 16, HEPA, and Activated Charcoal filters stand out for their efficiency and versatility.

  • Worker Protection: CABAIRE Systems’ advanced filtration technology protects workers from dangerous particulates, ensuring a clean and safe working environment.
  • Regulatory Compliance: By aiding in compliance with OSHA regulations regarding silica dust and chemical exposure, CABAIRE Systems help businesses avoid costly fines and penalties.
  • Comprehensive Filtration: Whether trapping silica particles with MERV 16 filters or absorbing gases and odours with activated charcoal, CABAIRE Systems offer comprehensive protection against a variety of airborne contaminants.
  • Self-Cleaning Mechanism: CABAIRE Systems’ over-pressure feature ensures that no particulates escape into the cab, effectively cleaning the environment within the vehicle.
  • Pressure Monitoring: Integrated pressure monitoring systems keep track of in-cab pressures, providing valuable data for maintaining optimal filtration performance.

Red Dot also designs and manufactures a complete line of heavy-duty off-the-shelf, ready-to-install HVAC units and kits to keep operators comfortable while working in the most rugged and demanding environments. These include:

  • Rooftop, backwall and under-dash units for commercial, industrial, mining, and construction equipment.
  • Direct drive, hydraulic and electric compressors
  • Backwall units

The air filtration systems are available from NAPA. With a national branch network serving trade, industrial and mining customers, supported by the know-how and Australia’s largest leading range, the company is well- positioned to help small and large companies meet ISO 23875 requirements.

As Wesley Skewis, NAPA Industrial – Sales Manager explains: “NAPA is more than parts, we’re here to take your business further.”

The clean and efficient operation of filters is critical for worker safety.
