Variflow® HT Filters are designed to provide high filtration efficiency in high temperature applications. Three temperature ranges are available (500°F, 750°F and 900°F) to meet the operating requirements of any system.

The cell sides are constructed of Aluminized Steel, which will not flake off or become brittle at elevated temperatures. Cross braces and expanded metal faceguards on the air entering and leaving sides provide additional support and rigidity. Corrugated Aluminum separators with rolled edges maintain proper spacing between pleats at all air flow rates and operating temperatures.
