In the production of PP blown candle filter cartridges are used automatically controlled machines of high technology.

• The inserts are made of 100% polypropylene, which is ideal for most filtration requirements.
• The filter mat fiber is designed to ensure its structural integrity throughout its life.
• Excellent nonwoven fiber properties ensure optimum fluid cleanliness and eliminate foaming.
• The 100% PP construction ensures excellent chemical compatibility with various process fluids and applications.
• The graded fiber density ensures optimum particle retention and ensures consistent filtration performance.
• Without binders, additives, and lubricants.
• Low-pressure drop, high dirt collection capacity, and long service life.
• Meets FDA requirements
• Inner diameter: 1.1“ (28 mm)
• Outer diameter: 4.5“ (115 mm)
• Filtration ability: 5 µm
• Length: 10" (250 mm),20"(­508 mm)

Most often the differential pressure is measured by pressure gauges before and after the filter and after reaching the limit pressure it is necessary to replace the filter elements.
