This upgraded filter is corrosion resistant and has a check valve to ensure a complete stop in chemical draw when switching from low to high pressure. Using a weighted filter, such as this, also keeps it at the bottom of your chemical tank ensuring a steady chemical supply.
Chemical Filters are a must-have when using down stream chemical injectors. Often, chemical is mixed from dry substrates and over time, will collect on the bottom of your chemical tank. Without a filter, this crystalized debris, sand, and other particulates can be drawn into the line and clog elsewhere. These inexpensive filters will prevent costly delays and downtime when on the job.
