MicroMetl Powered Exhaust

In some applications when economizers bring in outside air, barometric relief dampers aren't capable of removing enough return air to provide the desired building space pressure. Power exhausts can be added to an economizer to relieve this building pressure.

Most power exhausts are activated based on the position of the economizer's outside air damper, however MicroMetl also offers power exhaust control systems that modulate the amount of power exhaust based solely on the pressure in the space. This allows many applications to meet current ADA requirements related to pressure required to open and close doors in retail and commercial applications.

Power exhausts are available for all economizer and HVAC applications and include those with propeller fans and centrifugal blowers.
