Summary
Product identification
Purtrex melt blown depth filters are designed for general industrial use. They feature a progressive graded density to capture particles throughout the entire filter.
Features and Benefits
- Exceptional value for general applications
- Progressive graded density captures particles throughout the entire filter
- Long life and lower change-out frequency
- Exceptional dirt holding capacity
- Pure polypropylene construction
- No wetting agents, solvents, antistatic agents, or binders
- Made with 90% to 100% pre-consumer recycled polypropylene material to reduce landfill waste
- Meets FDA requirements for food and beverage contact
- Made in the USA
Applications
- General industrial use
- Potable water filtration
- Chemical filtration
- Plating baths
- Amine filtration

Efficiency Information
The document includes a table (Table 2) detailing removal efficiency based on a modified ASTM 795 test procedure, showing removal ratings at 90.0%, 99.0%, and 99.9% efficiencies for various micron ratings. It also notes that the efficiency of nominal filters varies by application. A graph (Graph 1) illustrates clean water flow rate based on a 10 in length filter, showing differential pressure (mbar, psi) against flow rate (lpm, gpm) for 1 µm, 3 µm, 5-10 µm, and 20+ µm filters. See the official PDF for exact tabulated values and graph details.
