Pressurization Module (PM300/450)
Home » Products » Pressurization Units »
VoltAire Systems Pressurization Modules are fan powered to provide positive pressure to a building or room. The module is designed to be economical and attach seamlessly to a wall mount HVAC unit. Pressure levels are manually adjusted using a rotary potentiometer. A mist eliminate and final filter reduce the amount dust or debris from entering the pressurized area. A separate building pressure monitoring station (sold separately) may be provided to allow the user to adjust the potentiometer to the desired building pressure.
