B-Line Eaton series enclosure climate control, ANSI 61 gray painted finish, Steel, Fans filter box, Climate control products, Filter slides in and out

The filter slides in and out of the K2P40 box, so it can be pulled for cleaning or replaced without removing the assembly from the enclosure. That matters on a panel in a dusty plant, where the filter is the part that gets attention on a maintenance schedule.

The K2P40 measures 7.38 in wide by 6.13 in high with a 2.37 in depth dimension. Lay those out against the flat panel area you intend to use and confirm you have clearance behind the door for the 2.37 in dimension before you cut, since internal components sit close to the door skin on shallow enclosures.

Yes, the K2P40 is UL/CUL listed, which covers both US and Canadian jobs. That is the line an institutional or MRO reviewer usually wants on the submittal for anything cut into a panel door.

The K2P40 is a fan filter box, the filtered air inlet or outlet side of an enclosure ventilation setup. Eaton groups it under its climate control products alongside heaters and thermostats, but this part moves and filters air rather than adding heat. If your problem is condensation in an unheated cabinet rather than heat buildup, an enclosure heater is the item to look at instead.

It is painted ANSI 61 gray, the standard industrial enclosure gray used across B-Line and most other electrical enclosure lines, so it blends with existing panels finished to the same standard. The housing is steel, not plastic, which is worth knowing if the panel is in a location where a plastic grille would get knocked.

Order model K2P40, the Eaton B-Line series enclosure fan filter box in ANSI 61 gray painted steel. It is a single configuration, so there is no finish or size suffix to specify.

It weighs 3 lb, light enough that a standard steel enclosure door carries it on its own mounting hardware with no added bracing. The steel body accounts for most of that weight.
