Series MAC is designed specifically for the control of cold fresh air into buildings, mechanical rooms and fruit rooms. The body is insulated and the damper has a tight metal-to-metal seal that ensures dependable low temperature operation.

Passive fresh air inlet ducts are sometimes plugged and therefore become unsafe. Alternatively, Motorized Dampers are safe as there is no need to plug the duct. The result is added comfort, added safety and a saving in energy costs.
