Filters are more important today than ever before. Process tolerances, safety standards, environmental standards and waste-reduction requirements are only becoming stricter. Filters often play a key role in achieving these difficult goals. The following four application examples illustrate the importance of following the preventive-maintenance and filter-replacement schedule.
Reason 1: reducing the cost of engineering and technical support
Problem: significant funds are spent on producing compressed air. The higher the air pressure — the more expensive its production. Therefore, any opportunity to lower the pressure in the lines can save money. All filters become clogged over time, which makes it harder for the flow to pass through. To overcome this resistance, the pressure has to be increased. The ideal moment to replace a filter element is considered to be when the cost of overcoming the increased differential pressure begins to exceed the cost of replacing the filter.
Donaldson's solution: the Donaldson Economizer system, installed on DF-series filter housings, can automatically calculate the maintenance interval. At the moment corresponding to the lowest costs, a signal to replace the elements will be given.

A unique compact design combines three cleaning stages in a single filter housing. Perfectly suited for removing oil aerosols, vapors and solid particles from compressed air.
Reason 2: reducing production costs
Problem: Modern production lines use hundreds of thousands of mechanical devices, a significant proportion of which are equipped with a pneumatic drive. The efficient operation of pneumatic equipment depends on tightness and tight tolerances.
Solution: Donaldson filters extend the service life of pneumatic equipment and prevent unexpected shutdowns. Since shutdowns lead to production losses and the expenditure of internal resources, and often require third-party specialists, Donaldson filters can significantly save your money.

Reason 3: protecting the brand's reputation
Problem: A product recall in food and beverage production can pose a serious threat to a company's reputation. Sterile filters are subjected to heavy loads, so they must be replaced in accordance with the manufacturer's recommendations.
Donaldson's solution: Donaldson filters for sterile air can withstand the thermal stresses that arise during hot-steam sterilization cycles. Donaldson subjected these filters to extended testing and, based on the statistical data obtained, determined the maximum permissible number of sterilization cycles without damage to the filter.

Reason 4: requirements of regulatory authorities
Problem: A Hazard Analysis and Critical Control Points (HACCP) plan and a Hazard Analysis and Risk-Based Preventive Controls (HARPC) plan covering the use of filters require compliance with the manufacturer's recommended replacement intervals and the keeping of appropriate documentation to demonstrate compliance. If problems with product quality or safety are linked to a failed filter that was used beyond its intended service life, the end user may incur significant costs and damage its reputation.
Donaldson's solution: To ensure your protection, all Donaldson sterile filters are 100 % integrity-tested and have a traceable serial number. How long ago did you check your filters?
