Pleated Bag Filters
If you are a process or in-line engineer supervising pleated bag filter change-outs, contact us. We can cut your operating costs.
Sample pleated bag filters that fit the common P2 size industrial housings can be sent to your facility promptly. Major improvements in filter service life can be readily demonstrated using Hoff Engineering industrial pleated bag filters.

High Capacity Bag-Sized Pleated Cartridges
Our felt and cellulose pleated bag filters save industrial filter bag users money every working day. Compared to regular micron rated filter bags, they incorporate six to eight times the filter surface area. That means fewer change-out and less manufacturing downtime. Hoff Engineering extended life pleated filter bags are available in a wide variety of filter media: polyester, polypropylene, cellulose and synthetic/cellulose blends.
Cutting edge research in the Fibers Technologies constantly bring new opportunities for filtration costs savings. The latest filtration media innovations are incorporated into our specialty pleated filter bag designs. Hoff Engineering utilizes proprietary combinations of small and large diameter media fibers to provide high solids loading and long service life. Given the goal of a certain efficiency rating for a liquid filter, we target low pressure drops to yield high flow rates. Thus Hoff Engineering’s pleated bag filters have a clear edge, consistently outperforming conventional liquid filter bags in demanding chemical process, coolant, waste water, metalworking, paint and coating, and parts washer applications.
They fit the common multi-bag and single bag P2 size housings made by FSI, Rosedale, Eaton, Eaton legacy (Ronnigen-Peter and Hayward) and Krystil Klear. We also manufacture pleated bag filters in the P1 and P4 sizes.
