Abstract
A fan grill for use with a fan associated with an inlet ring is configured to flush mount in an inlet ring and to serve as a safety guard to help prevent finger insertion into, and to help inhibit debris from entering a fan. The fan grill can impede and disturb gas flow to a fan less than by using a non-flush mounted grill or guard. The fan grill includes radial ribs, concentric circular ribs and radial support ribs to form a grate, and tabs. The tabs and the radial support ribs are configured to bias the fan grill against a wall of an inlet ring to securely connect the fan grill in the inlet ring. The fan grill can be readily installed and securely connected to inlet rings or housings of existing fans.
