Series ER filter grilles have grid cores capable of transferring or returning high air volumes with minimum air pressure loss. They match in appearance grid louvers on luminaries.
The core consists of a 1/2″ x 1/2″ x 1/2″ aluminum grid in a sturdy extruded aluminum U frame which swings in or out of the fixed back pan for easy access to the 1″ standard filter or filter media (supplied by others). Two locking arms opposite to the two concealed hinges provide secure locking of the core in an unobtrusive manner.
