AIR FILTERS Boston Gear's Air Filters are designed for general applications in compressed air systems where effective filtration and removal of solid water particles and impurities are required. Order filters with an automatic drain when the filter will be installed in an inaccessible area and when large quantities of water are present. Water vapor will pass through these filters and could condense into liquid form downstream as the air temperature drops. An air dryer would be required if water condensation could have a detrimental effect on the application. • Removes liquid and solid contaminants...
