ECOTIGHT SHUTTER IMPROVES FAN EFFICIENCY
AND REDUCES COLD AIR LEAKAGE
Manufactured to your desired custom size, the EcoTight Shutter is made of heavy-duty, durable twin wall profile frame for longer life and stability. Its aerodynamic design allows for maximum air performance while minimizing light into animal room. Based on a 30" shutter test (airflow only - not on a fan), the EcoTight Shutter had 21.8% more airflow and 17.1% less air leakage than Double L's current PVC Shutter.
