The entrainment of condensate along with air flow in compressed air systems to end-use applications is extremely harmful if the system is not drained regularly. The ideal solution for regular, effective draining of oil and moisture from a Compressed Air System is the Lenora Auto Drain Valve (LADV).
The Problem
Compressed air systems inevitably produce condensate — a mixture of water, oil, and dust. Without regular drainage, this condensate is carried downstream into pneumatic valves, actuators, and production tooling, causing corrosion, contamination, and premature failure.
Manual draining is unreliable. Float-type drains, drain the condensate but is prone to frequent repairs due to dust and debris. Neither solution gives you the precision control that a modern compressed air system demands.
The Lenora Solution
The LADV Series uses an advanced microprocessor-based timer controller to open the drain valve for a precise, adjustable duration at a configurable interval — draining condensate periodically.
Microprocessor-based controller for accurate, consistent drain cycle functioning. No drift, no wear-out of mechanical timing components.
Digital display for viewing the time set and time remaining for draining. Instant visual confirmation of operating parameters at a glance.
Adjustable ON time (1–9 seconds) and OFF time (1–99 minutes) to match your system's condensate generation rate precisely.
1–99 hours OFF time available upon request.
Precise digital setting eliminates the guesswork of manual draining intervals. Set once, and the microprocessor maintains exact timing indefinitely.
Virgin ABS enclosure for the timer. Aluminium diecast valve body. Every unit tested at Lenora's in-house facility before dispatch.
