Purex 111072 – Pre-Filter, Labyrinth F8, 5000i

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.

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

• 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
• Contains the particles inside for clean and simple disposal
• Standard captures particles to 5 micron at 40 – 60%
• Composite captures particles to 1 micron at 95% efficiency

• Extends the life of the main filter by capturing larger particles before they reach the HEPA filter
• 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
• 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 micron at efficiency of 60 to 80%
• Composite captures particles to 1 micron at efficiency of 80 – 95%
