Magnetically Operated No-Loss Drains GMNL500

Description Magnetically Operated No-Loss Drains GMNL500

The GMNL series offers environmentally friendly condensate drains that operate without electricity, using magnetic force to discharge condensate automatically.  GMNL100 and GMNL500 include integrated mesh strainers for valve protection. The integrated stainless steel strainer protects the valve, optimising the discharge performance. Drains have an IP68 rating for higher enclosure protection.

The GMNL series uses specially selected long-life magnets that ensure a reliable discharge operation. The discharge process is automatic, does not require electricity and there is no compressed air lost during the condensate discharge cycle. They are ideally suited in applications where power is not available, too expensive or not reliable.

Draining the moisture from compressed air systems ensures less downtime and damage due to rust and scale. Gardner Denver drains are designed for long life and require minimum maintenance. They are critical components in the quest for system efficiency and reliability. When a drain fails to discharge the condensate, the condensate can carry over into the system, causing a build-up of contaminants in dryers, receivers and filters. On multiple stage compressors, moisture carryover from the intercooler may allow liquid into the next stage, causing premature wear and a potentially catastrophic failure.
