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.
