## Abstract

The present invention relates to a V-type filter frame for receiving at least one filter media pack, said V-type filter frame being arranged to be mounted to a filter holding structure, the V-type filter frame comprising first and second side plates and a molded plastic rectangular front plate coupled to the side plates, said side plates each comprising a front edge portion and an opposite rear edge portion and the front plate having a front surface and a back surface, the back surface of the front plate comprising a first coupling portion comprising a first groove configured to receive the front edge portion of the first side plate, a second coupling portion comprising a second groove configured to receive the front edge portion of the second side plate, a trough for receiving a front edge of a filter media pack, extending between the first and the second coupling portion of the front plate, characterized in that said trough is in fluid connection with each of said first groove and said second groove when the first and second side plates are coupled to the first and second coupling portions of the front plate respectively.

## Claims

### Claim 1

A V-type filter frame for receiving at least one filter media pack, said V-type filter frame being arranged to be mounted to a filter holding structure, the V-type filter frame comprising first and second side plates and a molded plastic rectangular front plate coupled to the side plates, said side plates each comprising a front edge portion and an opposite rear edge portion and the front plate having a front surface and a back surface, the back surface of the front plate comprising:
a first coupling portion comprising a first groove configured to receive the front edge portion of the first side plate,
a second coupling portion comprising a second groove configured to receive the front edge portion of the second side plate,
a first trough for receiving a front edge of a filter media pack, extending between the first and the second coupling portions of the front plate,
wherein, when the first and second side plates are coupled to the first and second coupling portions of the front plate respectively, there is a void at the first groove between the front plate and the front edge portion of the first side plate, and a void at the second groove between the front plate and the front edge portion of the second side plate, wherein said first trough is in fluid connection with each of said first groove and said second groove, such that a fluid deposited in the first trough can pass through said fluid connection and into the voids, said fluid connection thereby allowing the simultaneous application of a fluid sealant to the first trough and grooves of the front plate.

### Claim 2 (depends on 1)

A V-type filter frame according to claim 1, wherein the back surface of said front plate comprises the first trough and at least a second trough for receiving a front edge of a filter media pack, each of the troughs extending between the first and the second coupling portion of the front plate, wherein each of the troughs is in fluid connection with each of said first groove and said second groove when the first and second side plates are coupled to the first and second coupling portions of the front plate respectively.

### Claim 3 (depends on 1)

A V-type filter frame according to claim 1, wherein the front plate further comprises an abutment surface arranged to abut a filter holding structure when mounted thereto.

### Claim 4 (depends on 1)

A V-type filter frame according to claim 1, wherein a bottom portion of the first trough of the front plate is sloped downward towards the first coupling portion of the front plate so as to direct fluid in the first trough towards the first coupling portion.

### Claim 5 (depends on 1)

A V-type filter frame according to claim 1, further comprising a rear plate coupled to the rear edge portion of the side plates, said rear plate comprising a trough for receiving a rear edge of a filter media pack.

### Claim 6 (depends on 1)

A method of assembling a V-type filter, comprising the steps of:
providing a filter frame according to claim 1,
inserting a filter media pack into the filter frame, such that a front edge of the filter media pack is received in the first trough of the front plate, and
pouring a fluid adhesive into said first trough such that said adhesive flows through the fluid connection to fill the voids at the grooves between the front plate and the front edge portion of the first and second side plates, respectively.
