Abstract: A system for cleaning a filter mounted over an intake opening of an air handling unit. A conduit is secured to the unit and includes a plurality of spaced nozzles arrayed against the filter. A supply tube connects to the conduit for supplying pressurized fluid through the nozzles to clear debris from the mounted filter. The pressurized fluid includes either liquid (typically water) or compressed air provided from any source or supply reservoir. A pump is incorporated into the supply tube for pressurizing the fluid. A separate filter incorporated into the supply tube filters the pressurized fluid prior to delivery to spray issuing conduit. A processor/controller is provided in combination with an arrangement of control valves for providing timed sequenced washing of multiple filters. A collection basin is provided for recycling used liquid for re-delivery and re-use.

Abstract: An assembly for installing a covering over an air intake opening in engagement with a surrounding perimeter extending face. A plurality of elongated supports attached to the perimeter extending face at locations around the intake opening, each of the supports exhibiting a forwardly projecting support surface within which is configured a slot. A plurality of fasteners install through an accessible end location of each support such that a base of each fastener is retained within and traversable along an interior channel defined in said support, a projecting portion of each fastener extending from said base and through said slot. A rigid mesh exhibits a generally rectangular outline which generally matches the arrangement of the elongated supports, an aperture pattern defined in the mesh permitting the projecting portions of the fasteners to extend through the mesh to retain the mesh over the forwardly projecting support surfaces.

Abstract: Embodiments disclosed herein generally relate to a method for forming a HAMR head. The method includes depositing a drop-on-demand mask on a portion of a surface of a slider using a drop-on-demand tool. The surface of the slider includes at least a portion of an NFT. A first protective layer is deposited over a remaining portion of the surface of the slider and over the drop-on-demand mask. The drop-on-demand mask and a portion of the first protective layer disposed on the drop-on-demand mask are removed, exposing at least the portion of the NFT. A second protective layer is deposited on the first protective layer and at least the exposed portion of the NFT. By using the drop-on-demand tool to deposit the drop-on-demand mask, the alignment between the drop-on-demand mask and the portion of the NFT is less stringent, and the drop-on-demand mask can be easily removed using a wiping tool.
