A half-barrel intake screen is disclosed. An embodiment operates by receiving an inbound EDI transaction, and translating the inbound EDI transaction to any combination of EDI outbound transactions and non-EDI outbound transactions. The spring, while in its active state, is positioned adjacent to and spaced from the base wall, defining a gap of sufficient size to permit the passage of at least one suture therethrough. The total heat exchange member is capable of exchanging sensible heat and latent heat between said first and second airflows, and defines therein a first air passage and a second air passage intersecting with and isolated from each other.
