Product Description

Air pulsation dampers are sealed containers that use compressed air within the container to provide cushioning. Air pulse dampers have a simple structure and are relatively inexpensive, their biggest disadvantage is that the compressed air gradually dissolves into the medium, causing the compressible air to become less and less effective in cushioning. To maintain their effectiveness, air pulse dampers must be periodically removed from the equipment and the medium inside must be drained to ensure that the internal space is clear. As a result, maintenance can be somewhat troublesome during use, making them suitable for systems that do not require high cushioning requirements. A simple method for selecting the volume is to multiply the volume of each stroke (in milliliters) by 26, which yields the minimum volume capable of reducing 90% of the pulses.
