A gas trap system for metal organic chemical vapor deposition (MOCVD) exhaust abatement operations is provided. The gas trap system may include a housing including an inlet configured to receive exhaust gas and an outlet. The gas trap system may also include a conical inlet shield positioned within the housing. The conical inlet shield may form a first path between the housing and the conical inlet shield, wherein the first path receives the exhaust gas from the inlet. The conical inlet shield may also cool the exhaust gas and cause the exhaust gas to be uniformly distributed in the first path. The gas trap system may also include a filter configured to receive the exhaust gas from the first path and to filter the exhaust gas, wherein the filtered gas exhaust is provided to the outlet.

Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a key slot disposed on the first housing end and a housing key element protruding from the first housing end toward the second housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element includes filter media and an endplate disposed on the first filter end. The endplate includes a central endplate opening, a key element configured for engagement with the key slot, and an installation guidance element formed along the central endplate opening. The installation guidance element is configured for engagement with the housing key element.

Methods and systems for recovering retained filtered fluid are provided.
