MasterCool Purge Pump Kit

Using this purge pump in your evaporative cooler can inhibit mineral buildup as it periodically expels water from the reservoir. The purge pump is installed directly in the cooler's electronic system, and because it uses less water than bleed-off systems, the MasterCool purge pump is far more efficient. MasterCool is a registered trademark of Champion Cooler Corporation. WARNING: This product can expose you to chemicals including benzene which is known to the State of California to cause cancer and birth defects or other reproductive harm.
