Ambient Air Tubesheet


  • Unique filtration design is especially useful in applications that require customized packaging of the filters to meet requirements for airflow, physical size, or integration with other equipment
  • Excellent alternative in industrial environments where dust loading is too high for standard HVAC panel-type filters


  • Ultra-Web® cartridge filters provide high filtration efficiency and long filter life
  • MERV* 15 filtration efficiency rating per ASHRAE 52.2-2007
  • Automatic pulse-cleaning design for continuous operation

Cost Effective

  • Low operating pressure drop reduces energy cost
  • Easy filter changeout for quicker maintenance

*The Minimum Efficiency Reporting Value (MERV) of this filter cartridge has been determined through independent laboratory testing using ASHRAE 52.2 (2007) test standards. The MERV rating was determined at a face velocity of 36 meters per minute / 118 feet per minute and loading up to 101.6 mm / 4 in. water gauge. Actual efficiency of any filter cartridge will vary according to the specific application parameters. Dust concentration, airflow, particle characteristics, and pulse cleaning methods all affect filtration efficiency. MERV 15 available in the U.S. only.

Ambient Air Tubesheet airflow

Operational Explanation

During normal operation, air flows inward through the intake duct and passes through the filter elements. Dust is collected on the outside surfaces of the elements. Clean air flows through the center of the elements into the clean air plenum.
