Pullner melt blown cartridges are available in five surface types. Use this guide to select the right option:
| Surface Type | Best For | Key Advantage |
|---|---|---|
| Standard (this product) | Clean liquids, cost-sensitive applications | Lowest cost per element |
| Groove Type | High solid content, high debris loads | ~3x dirt-holding capacity vs. standard |
| Orange-peel | High-viscosity fluids, elevated system pressure | Superior mechanical strength |
| Mini-grooved | Precision filtration where consistent accuracy is critical | 99% stable filtration accuracy |
| Matte | Liquids with mixed particle sizes where surface clogging is a problem | Surface interception layer prevents deep clogging |
Micron rating guide: 1-5 micron for pharmaceutical and electronics; 5-10 micron for RO pre-filtration; 20-30 micron for coarse sediment removal; 60 micron as a first-stage pre-filter upstream of finer elements.
