Key Benefits of Zero Air-Loss Condensate Drains

  • Saves energy (no air consumption)
  • Very resistant to clogging
  • Removes risk of condensate carry-over
  • Automatically adjusts to condensate levels
  • Long service intervals with safe, easy maintenance

Where there is compressed air, there is water. Condensation is the moisture that drops out of an air flow as it cools and is therefore a constant threat to cause expensive problems in a compressed air system. Condensate drain systems are necessary to keep water, dirt, wear particles, bacteria out of your system. The problems get worse if you operate lubricated reciprocating or oil flooded rotary screw compressors – which is just about everyone. Compressor oil makes its way into the distribution system with the compressed air. The mixture of oil, water, and dirt tends to build up a sludge that will ultimately jam or clog production equipment, air tools and drains. Zero air loss drains often qualify for energy efficiency rebates so call us today for more information on your condensate drains at  800.582.5162 or email us.
