Donaldson Ambient Air Tubesheet

Customized Ambient Air Dust Control

The Donaldson Torit® Ambient Air Tubesheet is a unique filtration unit designed to be a pre-filter in existing or built-up air handling and HVAC systems. ​​​​

Ambient Air Tubesheet

Main Benefits of the Ambient Air Tubesheet


The 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
The Ambient Air Tubesheet is an 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 with a MERV* 15 filtration efficiency rating per ASHRAE 52.2-2007 and an automatic pulse-cleaning design for continuous operation.


The low operating pressure drop reduces energy costs and
easy filter changeout for quicker maintenance reduces downtime.

Ambient Air Tubesheet 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.


*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.
