HOW TO SAVE MONEY, TIME & ENERGY Choosing the right cartridge filters can have a big impact on cost, performance and compliance
ALL AIR FILTERS ARE PRETTY MUCH THE SAME SO I’LL BUY ON PRICE…… If Filter A and Filter B offer the same rated efficiency and fulfil any required special requirements, then the lowest price filter would appear to be the better choice…. or is it? In practice, the opposite may be true and it requires a ‘Total Cost of Ownership’ calculation to know which is the best long term option.
MAKE SURE YOUR FILTERS MEET HEALTH & SAFETY LEGISLATION Before starting the evaluation, it is vitally important to ensure the filters will have adequate filtration efficiency and other characteristics in order to perform their primary function of air pollution control. There are clear Health & Safety guidelines relating to the permitted levels of different types of air pollutants and the filtration equipment supplier should provide a written guarantee stating the maximum emissions over a given period.
HOW MUCH DOES AN AIRFILTER REALLY COST? There are three main areas to consider: • Energy consumption • Electrical • Compressed air • CO2 emissions • Consumables • Cartridge replacement • Transportation • Inventory costs • Maintenance and Disposal • Labour costs • Disposal costs • Downtime
CONCLUSION • Filter cartridges/systems should not be chosen on price • Total Cost of Ownership (TCO) calculation is a useful tool for comparing the real costs of operating an existing dust collector with different filters. • TCO also provides a useful tool for evaluating the impact of energy-saving electrical components in the design of dust collection systems
