Putoline air filters, based on leading-edge open-cell foam technology, bring users major benefits, including:
- Improved performance through increased airflow
- Improved protection through finer filtration levels
- Substantial cost savings through serviceability and re-use
Fully reticulated (open cell) foam, as used in all Putoline filter products, consists of a honeycomb of tiny, interlocking cells of uniform size. When treated with specially formulated filter oil, each passageway is like hundreds of very small centrifugal/oil bath filters connected one to another. Through this, the foam traps and holds the particles throughout the entire volume of foam.
The development of this unique foam represents a major advancement in air filtration technology. As a result, foam air filters, when compared with paper or cotton gauze equivalents, combine great airflow capability, huge dust holding capacity, and very high filtration efficiency for even extremely small particles.
