Orion Fans has expanded its line of fan accessories with the LFG120B and LFG172B louvered fan guards. These heavy-duty filtered units help prevent dust and dirt from entering enclosures such as industrial cabinets, server cabinets and server racks. The fan guards also protect fingers from injury by the fan blades. Available for 120mm and 172mm fan sizes, the louvered fan guards are manufactured of UL 94V-0 flame-resistant plastic, and the filter media is a washable nylon fiber. Mounting hardware is also included with the guards.
