ABSTRACT:
A liftable housing form of pressure tight treating chamber is especially adapted to providing multiple stage treatments to catalyst support members, such as honeycomb-type elements, in order to place a catalytic coating on all of the interior surfaces of the multiple passageways through the elements. Power operated lifting of an open-bottomed housing permits the placement of members on sharp edged pin support means in the interior of the chamber such that passageways will not be blocked while the element is being subjected to vacuum, liquid coating, and air blowing stages.
