Understanding Industrial Air Filtration
Workshop air filtration systems are engineered to remove harmful particulates, oils, and odors from the breathing zone of operators and the general facility environment. Metalworking, CNC machining, and assembly operations generate significant amounts of oil mist, smoke, and dust. Without proper extraction, these contaminants settle on machinery, reducing precision and increasing downtime. They also pose serious health risks to employees, including lung damage and chronic respiratory issues.
Aeroex Technologies was established in 2001 in Barrie, Ontario, with a mission to transform industrial environments through advanced air purification technology. Over two decades, the company has evolved from a modest 2,400-square-foot workshop to a 15,000-square-foot facility, expanding its product lines to include the Maverick, Mist-Fit, ARO-X, and IRIS series. This history of innovation underscores the importance of selecting a partner with deep industry expertise.
Oil mist is a suspension of fine oil droplets in the air. These droplets are created during machining processes such as grinding, milling, and turning. If not captured, oil mist can create slippery floors, leading to safety hazards, and can interfere with subsequent processes like painting or welding. Effective filtration systems must capture these droplets before they disperse into the workshop atmosphere.
Key Filtration Standards and Efficiency
When selecting a filtration system, understanding efficiency ratings is paramount. The standard for measuring the performance of air filters is the MERV (Minimum Efficiency Reporting Value) scale. However, for industrial applications involving fine particulates and oil mists, HEPA (High-Efficiency Particulate Air) standards are often the benchmark.
Aeroex systems are designed to remove 99.9% of harmful particles from the air. This high level of efficiency is critical for maintaining cleanroom standards in inspection areas and ensuring the longevity of sensitive electronic components in assembly lines. The dual-stage filtration approach used in the IRIS series, for example, combines a MERV8/Carbon primary filter with a HEPA secondary filter. This configuration ensures that large particulates are captured first, protecting the HEPA filter and extending its life, while the carbon layer addresses odor control.
Energy efficiency is another critical standard. Variable Frequency Drives (VFDs) allow filtration units to adjust their airflow based on real-time demand. This not only reduces energy consumption but also significantly extends filter life. By lowering the fan speed when full capacity is not required, VFDs reduce the stress on the filter media, preventing premature clogging and maintaining consistent airflow performance over time.
Evaluating Filtration Technologies
Different workshop environments require different filtration technologies. The three primary technologies used in industrial air purification are mechanical filtration, electrostatic precipitation, and centrifugal separation. Each has distinct advantages depending on the type of contaminant and the scale of the operation.
Mechanical Filtration
Mechanical filtration relies on physical barriers to trap particles. This is the most common method for oil mist collection. The air is forced through a series of filters that capture contaminants based on size. Aeroex’s ARO-X series utilizes advanced mechanical filtration to capture fine oil mist and smoke. These units are designed for easy maintenance, allowing operators to replace filters quickly without specialized tools.
Electrostatic Precipitation
Electrostatic precipitators use a high-voltage electric field to charge particles, which are then attracted to and collected on oppositely charged plates. This technology is highly effective for fine particulates and can be more energy-efficient than mechanical filtration for certain applications. However, it requires regular cleaning of the collection plates to maintain efficiency.
Centrifugal Separation
Centrifugal separation uses rotational force to throw heavier particles against the walls of a chamber, where they collect and drain away. This method is often used as a pre-filter stage to remove larger droplets before the air enters the mechanical filtration stage. This extends the life of the primary filters and reduces maintenance costs.
System Design and Airflow Dynamics
The physical design of the filtration system must match the specific layout and operational needs of the workshop. Key factors include airflow volume, static pressure, and capture velocity.
Airflow volume is measured in cubic feet per minute (CFM). The system must be sized to handle the volume of air generated by the machinery and the ventilation requirements of the space. Aeroex offers engineered solutions that are customized to the specific CFM needs of each facility. This ensures that the system is neither underpowered, leading to poor air quality, nor oversized, leading to unnecessary energy costs.
Static pressure refers to the resistance the fan must overcome to move air through the filters and ductwork. Systems with high-efficiency filters have higher static pressure requirements. It is crucial to select a fan that can maintain adequate airflow even at high static pressures. Aeroex’s Mist-Fit series is designed for compact spaces, offering high performance in a small footprint while maintaining the necessary static pressure to capture mist at the source.
Capture velocity is the speed at which air must be drawn into the capture point to prevent contaminants from escaping. For oil mist collectors, this velocity must be sufficient to pull the mist from the machining zone before it disperses. The BlowBox, for instance, is a compact, dual downdraft blow-off station that captures hazardous mist during part blow-off with compressed air. This targeted approach ensures that contaminants are captured at the source, minimizing the volume of air that needs to be filtered.
