Abstract
A method of reinforcing a filter media pack as well as a reinforced media pack is provided. The method includes forming a media pack to have an inlet face and an outlet face. The method includes applying a reinforcing agent to the media pack. The reinforcing agent is applied in a flowable state. The method also includes hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack. Filter element having such a reinforcing structure is also provided.
Claims26
A method of providing reinforcing of a media pack comprising:
- forming a media pack to have an inlet face and an outlet face;
- applying a reinforcing agent to the media pack, the reinforcing agent being applied in a flowable state;
- hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack;
- and
- wherein the reinforcing agent is impregnated into the media of the filter media pack which forms a substrate, the reinforcing agent extends through the media prior to the step of hardening such that the reinforcing structure is comprised of a matrix of the hardened reinforcing agent and the media substrate.
A method of providing reinforcing of a media pack comprising:
- forming a media pack to have an inlet face and an outlet face;
- applying a reinforcing agent to the media pack, the reinforcing agent being applied in a flowable state;
- hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack;
- wherein applying the reinforcing agent includes immersing the at least one of the inlet face and the outlet face in the reinforcing agent in a bath of reinforcing agent in the flowable state.
A method of providing reinforcing of a media pack comprising:
- forming a media pack to have an inlet face and an outlet face;
- applying a reinforcing agent to the media pack, the reinforcing agent being applied in a flowable state;
- hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack;
- attaching a seal member to the media pack adjacent the reinforcing agent;
- and
- wherein a portion of the seal member overlaps with a portion of the reinforcing agent.
A method of providing reinforcing of a media pack comprising:
- forming a media pack to have an inlet face and an outlet face;
- applying a reinforcing agent to the media pack, the reinforcing agent being applied in a flowable state:
- hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack;
- wherein the step of applying the reinforcing agent includes absorbing the reinforcing agent into media of the media pack.
A method of providing reinforcing of a media pack comprising:
- forming a media pack to have an inlet face and an outlet face;
- applying a reinforcing agent to the media pack, the reinforcing agent being applied in a flowable state;
- hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack;
- wherein the reinforcing agent extends at least 0.100 inch into the filter media pack from the corresponding face.
A method of providing reinforcing of a media pack comprising:
- forming a media pack to have an inlet face and an outlet face;
- applying a reinforcing agent to the media pack, the reinforcing agent being applied in a flowable state;
- hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack;
- wherein hardening the reinforcing agent includes applying a second material to the reinforcing agent to cure the reinforcing agent.
