BW30LE-4040 Fiber Glass membrane element

Product Details

BW30LE-4040 delivers highest performance at lowest pressure resulting in less energy usage and lower costs. Elements with a hard shell exterior are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.
