SteelTec™ RO-335

The SteelTec™ RO-335 is manufactured by Microline and utilizes a standard manifold with proprietary filters. To retrofit your system to accept standard Microline cartridges:

Remove and discard hermatically sealed filter housings that contain filters inside.
Purchase (one time only) standard Microline sump housings and o-rings.
Install standard sumps with filters and o-rings. (NOTE: remounting the manifold may be required as the standard filter sump housings are 1-1/2" longer vs proprietary sumps).
