The Hidden Costs of Deferred Maintenance
Neglecting air filter maintenance results in cooling systems working harder, increasing energy use and costs. For example, a 50% clogged filter can lead to a 5% increase in kilowatt-hours (kWh) consumed, adding about $43.50 in energy costs per piece of equipment over six months. If the filter becomes 75% clogged, this increases to $55.00.
In a data center with 80 pieces of network equipment, clogged filters can consume an additional 22,400 kWh over six months, costing an extra $6,984. These rising costs highlight the hidden financial burden of deferred air filter maintenance.
Higher Power Consumption
When air filters are not maintained, cooling systems must work harder to maintain appropriate temperatures, leading to increased power consumption. For instance, a filter operating at 50% clogged will consume an additional 280 kWh over six months. As power consumption rises, electricity bills inflate, particularly during peak periods when cooling demands are higher.
Elevated Carbon Emissions
Along with higher energy costs, increased power consumption leads to higher carbon emissions, which significantly impact the environment. A single piece of equipment with a 50% clogged filter can emit an additional 249 pounds of CO2 over six months. In larger facilities, these emissions add up, further emphasizing the environmental impact of deferred maintenance.
Inconsistent Equipment Performance
Dirty air filters can lead to uneven airflow, causing inconsistent cooling and potential overheating. Overheated equipment risks premature component failure due to thermal cycling. Equipment operating above 40°C, for example, is 1.6 times more likely to fail. Downtime and repairs caused by these failures can be much more expensive than regular filter maintenance.
Proactive Maintenance for Efficiency and Sustainability
Proactive maintenance is key to preventing these issues. Here are some best practices:
- Regular Inspection and Replacement: Inspect and replace air filters every 3-6 months, or at least annually, to ensure consistent airflow and cooling efficiency.
- Use High-Quality Filters: Invest in filters that meet Original Equipment Manufacturer (OEM) specifications to ensure compatibility and efficient operation.
Universal Air Filters offers site surveys to evaluate your filter conditions and recommend preventive maintenance programs. Their kitted and packaged filters simplify inventory control and replacement.
By maintaining air filters regularly, you reduce energy costs, lower carbon emissions, and ensure reliable network performance, protecting both your equipment and the environment.
