Standard spun - Our highest selling spun filters, this is an excellent product value. High dirt holding capacity, combined with high efficiencies make this the product of choice for most water prefiltration applications. Individually machine packaged and boxed to contain cost. To reduce pricing we did not compromise product quality, we automated the packaging. |
| Gradient Density - A feature of all TechReps spun series, gradient density affords substantially increased filter life and effectiveness. With this construction, the outer areas of the cartridge are a larger micron rating, gradually tightening to the effective rating approximately 2/3 to 3/4 of the distance to the core. This allows the larger particles to be trapped within the outer areas of the element, leaving the more central portions free for removal of the smaller particulates. This provides, in effect, staged filtration within one cartridge. Higher flow rate with dramatically improved effectiveness is achieved. For the customer, this translates into better product value. No glue or binders are used in the spun series manufacturing. No pre-leaching or pre-flushing is required. All of the spun series meet or exceed FDA requirements. |
