SHUTTERS AN IMPORTANT PART OF VENTILATION SYSTEM

PVC ECOTIGHT SHUTTER IMPROVES FAN EFFICIENCY
AND REDUCES COLD AIR LEAKAGE

Don't let your expensive positive pressure system be compromised by losing pressure in the room when a shutter blade gets flipped over or stuck in an open position. The EcoTight Shutter was designed so there will be NO blade flip over or blades stuck in an open position. Manufactured to your desired custom size, the patent pending EcoTight Shutter improves fan efficiency and reduces cold air leakage. Its heavy-duty, durable twin wall profile frame was designed for longer life and stability of shutter. Individual Eco Adapter clips allow for expansion and contraction while reducing air leakage and light. Excellent cleanability with durability to withstand pressure washing. Widely used today in the outlet dampers of positive pressure facilities.

The IS8 TopJet Insulated Shutter minimizes air leakage and seals up tight with no cracks or spaces for air to come through. It also maximizes fan performance with minimal air restrictions. Double L's unique design has counterweight louver blades made of 3/4" insulation board encased in fiberglass with an R-value of approximately 6. Multiple infrared tests have shown a 20+ degree difference between the TopJet Gravity Insulated Shutter and the Standard Shutter - providing great energy savings, a safer environment for animals, and less buildup of moisture in buildings. The counterweight louver blades are uniquely designed to open from the top, directing airflow up towards the ceiling area. Easy to assemble and install.
