Monarch Extended Life Pleated Bag Filters

Extended Life Pleated Felt Filter Bags

Pleated filter bags manufactured from extended-life needle felt

The pleated filter bag is a new innovative product. It is a great alternative to the conventional filter bag, using a unique folding structure, the pleated filter bag provides up to four times the filtration area as compared to the regular filter bag. This extends the lifespan of the filter bag, resulting in a significant reduction in the amount of replacement downtime required.

The choices of either polypropylene or polyester can be applied to a wide range of applications in various industries, and the pleated filter bag is compatible with various equipment currently using conventional filter bags, eliminating the need to invest in any new equipment (eg. filter housings).

Pleated Filter Bags

Please note:
As with any extended life filter material the actual lifespan of the filter bag is dependent on the Solids Loading, Particle Size Distribution and Particle type.

Available in Nominal Rated and Absolute Rate polypropylene or polyester felt with efficiencies up to 99.9%.

1. Conical cap seal assures bypass-free performance.
