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.
Maintaining indoor air quality is vital to the health and well-being of a building's occupants. An Energy Recovery Ventilator (ERV) allows fresh air into a building, while retaining pre-conditioned heating or cooling.Let me better explain.he air-streams actually switch temperatures; the 70Â°F becomes 0ÂºF, and the 0ÂºF becomes 70Â°F. This is the core theory behind Energy Recovery AKA -- Air Exchange. An ERV operates on the basis of this air-to-air exchange theory.
