What Causes Facet Syndrome? Facet syndrome is generally the result of the natural aging process. However, the initial cause of arthritis, or facet syndrome, may also be an injury or overuse of the joints in youth. Another possible cause of facet disease is spondylolisthesis, which is when one vertebra â usually in the lumbar spine â slips forward over the lower vertebrae. When the facet joints become inflamed due to injury or age, the result is stiffness and pain.
An energy recovery ventilator (ERV) is a type of mechanical equipment that features a heat exchanger combined with a ventilation system for providing controlled ventilation into a building.
Energy Recovery Ventilators (ERV) from BROAN are typically recommended for use in warmer climates where it is desired to remove humidity from incoming fresh air. While not a dehumidifier, ERV systems transfer moisture from incoming, humid air to the stale indoor air that is being vented to the outside.esidential balanced ventilation systems introduce fresh air alone, or include Heat Recovery (HRV) or Energy Recovery (ERV) features. Select the unit that best matches the square footage requirements of your home or small office.
