Filtration media finishes for Donaldson filters UK

Each size multi pocket filter mentioned above is available in three different finishes. Each of these have different properties to suit your processes.

• Standard Polyester - For general dust collection, these filter bags are made from a high quality glazed polyester needlefelt.  
• Antistatic Finish - These filters are suitable for applications where static electrical charges can build up from certain combustible dusts such as ground plastics, sugar and flour.
• Universal Chemical Finish - This finish allows the filters to resist moisture & oil. UCF multi pocket filters are recommended when the filter bags need to be either hydrophobic (repels water) or oleophobic (repels oil).

When do I need to replace my Donaldson bag filters?

Is your clean air outlet discharging dust? This may be due to filter damage. 

Routine inspections can help to minimize downtime and maintain optimum system performance. It is important to check your filter unit regularly and replace any damaged or torn filter bags as necessary.

Always use proper safety and protective equipment when removing contaminants and filters. Dirty filters may be heavier than they appear. Use care when removing filters to avoid personal injury and/or property damage. Turn power off and lock out all power before performing service or maintenance work. Do not operate your dust extraction filter unit with missing or damaged filters.
