Magnetically operated level sensed condensate drain GMNL10, 100 & 500
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.
The GMNL10 is a magnetically operated zero air loss drains that discharge condensate from all compressed air systems by using a unique technology based on magnetic forces and without the usage of electricity. The environmentally-friendly GMNL100 removes all types of condensate from compressed air systems up to 100 m3/min while the GMNL500 is ideal for larger applications up to 500 m3/min with exceptionally large condensate discharge capacity of 4,800 l/h at 16 bar.
Product features
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. The integrated stainless steel strainer protects the valve, optimising the discharge performance. Drains have an IP68 rating for higher enclosure protection.
