Abstract

A guard configured to form an air flow channel with a space access device and to clear debris therefrom includes a surface configured to interface with an opposing surface of the space access device to form the air flow channel. A connector is configured to attach the guard to the space access device so that the surface and the opposing surface are oriented in predetermined positions to establish the air flow channel. A wiper extends from at least a portion of the surface, the wiper being configured such that upon rotation of the guard relative to the space access device, the wiper contacts and moves the debris.
