The lowest cost spun-bonded cartridge in the SPECTRUM range, the TruDepth Economic cartridge is ideally suited for batch processes where repeated change-out is required. With a graded density construction, this entry level cartridge is excellent at preventing premature blinding of other filtration systems further downstream.

As with all of the TruDepth range, the ESP from SPECTRUM benefits from a strong self supporting structure, manufactured from FDA compliant materials.
