Pressurization Units

Home » Products » Pressurization Units

VoltAire pressurization systems provide positive or negative pressure to a building or room. The systems automatically maintain pressure relationships with adjacent areas or ambient air with a high efficiency variable capacity fan. Air is filtered with 1″ pre-filter and 2″ final filter with MERV ratings up to 14. The pressurization controller modulates the pressurization system capacity to maintain the set point pressure, measured in inches of water column. A low pressure alarm is provided via dry contacts.

PU1600 Series

VoltAire Systems PU1600 Series Pressurization Units are designed to provide the ability to apply positive or negative pressure to a building or room. Pressure levels are monitored by an internal controller that modulates airflow to maintain room/building pressurization. Filters prevent any potential dust or debris from entering the pressurized area.
