Enclosure	FRP panels — light, corrosion resistant, UV stabilised
Arrangement	Multi-cell modular for capacities above one cell

Notas de diseño

• Structure you can walk onGalvanised columns and beams carry walkways and ladders without relying on the FRP shell for stiffness.
• Energy-recovery fan cylinderThe diffuser-shaped cylinder recovers exit kinetic energy, which shows up as lower shaft power for the same airflow.
• Drive condition on displayOil temperature and vibration alarms on the reducer turn an unplanned outage into a scheduled service call.
• Single cell, large capacityOne GFNL₂ cell covers the duty of several smaller FRP cells, which cuts plot area and interconnecting piping.
