About this item

The Parker Airguard Variflow® Series are rigid-cell extended surface filters engineered for commercial and industrial HVAC systems requiring consistent efficiency and structural integrity under demanding conditions. Available in MERV 11, 13, and 14 efficiencies, Variflow filters use microglass paper media and corrugated aluminum separators to maintain low pressure drop and uniform airflow.

Constructed for durability, the Variflow family includes multiple configurations—such as the VMA model, featuring all-metal construction without headers, is ideal for high-temperature or high-humidity environments. Designed to perform in variable air volume (VAV) systems, these filters are rated for temperatures up to 500°F (260°C) and deliver energy-efficient, long-lasting air filtration for commercial buildings, healthcare facilities, and industrial plants.

  • Available in MERV 11, 13, and 14 efficiencies
  • Nominal depths of 6" and 12" for flexible installation
  • Rated for 250 to 500 FPM face velocity
  • Handles airflow capacities from 500 to 2000 CFM
  • Rigid cell construction ensures durability in turbulent or variable volume systems
  • Water-resistant microglass paper media with antimicrobial option
  • Operating temperature limits: 350°F (metal construction)
