Orion Fans has expanded the industry’s lowest cost louvered fan guard product offering to include sliding and hinged versions. Designed to simplify installation and maintenance, the heavy-duty LFGS Series (sliding) and LFGH Series (hinged) louvered fan guards make it easier to access and change filters. Louvered fan guards are more robust than standard plastic fan guards and provide ingress protection against fingers, dust, accidental contact and moisture. All Orion Fans louvered fan guards feature UV protection with an IP44 rating, and when assembled with a fan, can achieve an IP54 rating or higher. This rating ensures that the equipment will operate in dusty conditions and resist splashing water. The LFG series can also maintain an equipment’s NEMA 12 rating when used with an Orion Fans Harsh Environment fan.
