A diffuser baffle for use in an in-line wastewater grease interceptor. The diffuser baffle lies within a grease collecting chamber between the inflow and outflow of a grease interceptor. The diffuser baffle has an open bottom which is sized and shaped respectively to fit into the grease collecting chamber. The diffuser baffle has an end operatively connected to the inflow opening to permit wastewater to flow into the body through the open bottom. The baffle has a downstream end which includes a deflector portion to deflect a wastewater stream in a direction generally into the grease collecting chamber. The body also includes a number of apertures to permit the deflected wastewater stream to pass through the baffle and into the grease collecting chamber, where FOG will separate before waste water exits the chamber through the outlet baffle.
There is disclosed a roof vent having rain control means to reduce rain water splashing into the opening in a roof vent. The baffle has a number of ridges or channels that direct rain water into a number of droplet pathways. The falling water creates a rain curtain that deflects rain water that enters into the roof vent from travelling into interior of the building. At the base of the roof vent is one or more splash deflectors that changes the angle of water impacting the base of the roof vent to limit the amount of deflected water that can enter into the opening in the roof vent. The rain curtain and one or more splash deflector may act in concert to further divert rainwater.

The base may include a pair of moisture deflecting features along at least a portion of one of the nonslope sides to prevent moisture flowing along the base from within an area on the base covered by the cover to outside of the covered area at the nonslope sides. The base may also include a water deflecting ridge on its underside positioned between a downslope edge and the aperture to deflect water away.
A vent for venting a building enclosure. The vent has a cover attached to a base with at least one attachment structure. The base has an attachment element for attaching the base to the building enclosure and an aperture to permit gas to pass in to and out of the building enclosure through the base. Preferably a moisture directing means is associated with an underside surface of the cover to direct and guide moisture therealong so that when the vent is installed on the building enclosure, moisture adhered to the underside surface of the cover will move under the influence of gravity to the moisture directing means which will in turn direct the moisture therealong to fall onto the base outside of the aperture. The cover may include a slanted side wall portion and the aperture is positioned on the base such that the center of the aperture is displaced from the center of the cover toward the slanted side wall portion. The base may also include a pair of moisture deflecting features along at least a portion of one of the nonslope sides of the vent to prevent moisture flowing under the influence of gravity along the base from with an area on the base covered by the cover to outside of the covered area at the nonslope sides.
