Chrome Eliminator CE-1 Specification

Chrome Eliminators (C/E's) are low energy systems which generate less than 8" of internal static pressure. The average water consumption rate for a 20,000 CFM unit is only 15 gallons per hour. The C/E has no internal moving parts to wear or replace, and Chrome can be recovered from both the gas stream and the filter.

The standard Chrome Eliminator is constructed of Type 1 Grade 1 Gray PVC. This material is recommended for high chrome applications. The estimated minimum service life of a filter is 5 years under continuous use.
