The Legacy of Reliability
With the roots of its design originating back in 1969, the MAS series is engineered for the harshest conditions. For over 50 years, Harrison has been the one name professionals have staked their lives on; and the lives of others.
The airflow pattern of the MAS makes it perfect for compartments, dunnage areas, under chassis, and anywhere you have a straight-thru airflow requirement. It is built to be maintained, with every maintainable part accessible in under a minute.
Straight-Thru Airflow
Perfect for compartments, dunnage areas, and under chassis installations where linear airflow is critical for cooling.
Built with the Mechanic in Mind
All maintainable parts are top accessible in under a minute, drastically reducing service time and keeping your fleet operational.
Trusted in Critical Response
Over 50 years of proven durability in the field.
