- The Static Pressure Regulating Dampers are barometric relief. dampers used to by-pass excess air pressure on zoned systems. The. dampers automatically respond to the air pressure in duct as the. various zone dampers open and close. As zone dampers close off air to a number of zones, the supply air. pressure in the duct system will increase. This increase in air pressure.

Shock absorber A shock absorber (in reality, a shock damper) is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot.

How to Freeze Butter Yes, you can freeze butter with great results. As long as the butter you're freezing is fresh, it should keep for a year or more. Butter has a shelf life of around four months in the refrigerator, so this will buy you a considerable amount of time. After a year, your frozen butter will still be safe to use (assuming it's remained frozen the entire time), but you may start to notice signs of freezer burn.
