45-55%), and three capacity levels. Constructed with high loft media
enclosed in a durable, moisture resistant beverage board frame, the
Multi-Pleat provides high dust arrestance and long life at rated air flows
up to 625 FPM. Multi-Pleat filters are also available in a wide
range of styles for specialized applications, such as Side-Access and High
