Premium HVAC pre-filters and overspray floor media engineered to withstand winter extremes and wildfire particulate load.
Calgary is the dynamic economic center of Western Canada, home to robust oil & gas support industries, aerospace maintenance, manufacturing, commercial real estate, and large-scale spray painting processes. In these demanding sectors, air pre-filtration is not just about equipment longevity; it is a critical regulatory and operational requirement.
Operating within Alberta requires addressing local meteorological variables: extreme winter temperatures reaching down to -40°C, high atmospheric dust counts from prairie winds, and the increasingly frequent threat of heavy wildfire smoke (PM2.5) during summer. These variables require panel pre-filters with low initial pressure drops, superior dust holding capacities, and high resistance to structural collapse under freezing conditions.
"For industrial coating operations in Calgary, managing both inlet supply filtration and emissions arrestment is closely regulated by Alberta Environmental Protection guidelines. Implementing a multi-tier filtration approach prevents excessive emissions and optimizes fan energy consumption."
Integrating premium Panel Pre Air Filters and Paint Mist Exhaust Filters to maximize efficiency and ensure environmental compliance.
Heating cold fresh air in Calgary’s sub-zero winters represents a significant utility cost. High initial resistance filters load system fans, driving up energy costs. Our low pressure drop synthetic panel pre-filters are engineered to maximize air velocity while minimizing resistance, lowering winter energy requirements.
Overspray discharge must comply with strict municipal and provincial particulate limits. Utilizing our Paint Mist Exhaust Filters (such as our high-performance DPA Paint Arrestor Pocket Filters or standard Fiberglass Paint Stops) prevents paint particulates from depositing on extraction fans, stacks, and the surrounding environment.
For cleanroom environments, electronic fabrication, and hospitals in the Calgary region, replacing deep-pleated H13/H14 HEPA filters is highly expensive. Utilizing high-efficiency G4 and F9 panel pre-filters extends primary HEPA life by up to 250% by capturing larger particles early in the airflow path.
