Purex 200316 is a Pad pre-filter and Extends the life of the main filter by capturing larger particles before they reach the HEPA filter. Captures particles to 5 microns at an efficiency of 40 - 60%.

Pre-filters are designed to capture larger particles before they can enter the main HEPA filter.

Without pre-filters, the life of the main filter would be much shorter.

A variety of media and designs are available to allow Purex extractors to be used in a wide range of processes.

Pad pre-filter

• Extends the life of the main filter by capturing larger particles before they reach the HEPA filter
• It fits neatly under the main filter
• Graduated fiber matrix delivers excellent particle capture capacity
• Ideal for low-volume applications or where small amounts of particles are produced
• Captures particles to 5 microns at an efficiency of 40 - 60%

Pleated bag pre-filter

• Extends the life of the main filters by capturing larger particles

• Provides additional particle capturing capacity
• Ideal for processes where large amounts of particles are produced
• It contains the particles inside for clean and simple disposal
• Standard captures particles to 5 microns at 40 - 60%
• Composite captures particles to 1 micron at 95% efficiency

Patented Labyrinth pre-filters

• Extends the life of the main filter by capturing larger particles before they reach the HEPA filter
• It fits neatly under the main filter in integral Purex extractors
• Graduated fiber matrix delivers excellent particle capture capacity - up to 20 times more than a standard filter
• Ideal for medium-high volume applications
• It contains the particles inside for clean and simple disposal
• Composite material available for extra filter life and filtration down to 0.5 micron
• Standard captures particles to 3 microns at an efficiency of 60 to 80%
• Composite captures particles to 1 micron at an efficiency of 80 - 95%
