SHUTTERS ARE AN IMPORTANT PART
OF YOUR 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 patented 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.

Fully tested as described by the Air Movement and Control Association, Double L's custom made PVC Shutters are manufactured to ISO9001 standards. Custom made to specifications, Double L's PVC Shutters are low maintenance, can withstand heavy pressure washing, and are easy to repair. PVC Shutters will never rust, rot, or corrode.
