Our Selection of 4040 GPD Membranes

Vontron is a top brand in reverse osmosis filtration, and we stock their 4040 GPD membranes for high-capacity water filtration, removing anything from dissolved solids to harmful compounds in the water.

Their membranes have incredibly tiny pores at a size of 0.0001 microns that filter out even the smallest impurities like heavy metals, ensuring your fish tank is full of pure water with a balanced pH.

Housings are also available for these membranes, which are crafted from durable stainless steel. They can be used for fishkeeping, window cleaning, agricultural tasks and more. They are made to sustain large amounts of water and constant heavy-duty use.
