Products Description
Melt blown polypropylene filter cartridges are constructed from 100% polypropylene media, effectively capturing suspended solids and process contaminants in liquids. Designed with multi-layered fibers and a graded pore structure, they deliver efficient depth filtration. Widely used in industrial and commercial water applications.

FAQ
Q: What causes rapid increase in differential pressure (ΔP) after installation?
A: Common causes: Excessive solids content in the inlet water, improper micron rating selection, poor gasket sealing leading to cartridge bypass, or sudden influx of particulate matter. Inspect seals and inlet water quality.
Q: What is the typical service life of a filter cartridge?
A: Typically 3-6 months under continuous operation. Service life varies by application. We recommend monitoring differential pressure and replacing cartridges periodically based on specific operating conditions.
Q: What is the delivery lead time for custom orders?
A: Standard custom orders have a lead time of 10-15 business days. For urgent needs, we offer expedited production with a delivery lead time of 5-7 days.
