ViroGuard contains grease and cleaning solution even in below-freezing temperatures — no icy roof hazards or frozen pad problems.
Installation includes extra-strength stainless steel Virospec hinges, ensuring your fan is properly hinged and protected during all future cleanings.
Any competent HVAC contractor can install the unit easily using our step-by-step installation guide and basic tools. Includes re-wiring.
