Units to pressurize buildings or rooms with filtered air to maintain positive or negative pressure.
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.
