MRSI recently introduced the air-knife vacuum system for cleaning epoxy dispense needles and it is now a standard feature on all MRSI dispense systems. The accessory automatically cleans needles of built up epoxy during a production program. The system lowers the needle through a hole into a stream of high pressure air from the air knife. The air forces excess epoxy from the needle. A vacuum system pulls debris away through a mesh to ensure the needle is thoroughly cleaned. This maintenance free process replaced a mechanical sponge system. The sponges in that system could be used for a limited time until they were contaminated. The air-knife system is available as an upgrade for any MRSI machine with the legacy sponge system.
