NA750 Mechanical Drain

NA750 Series

No Air Loss Condensate Drain

The NA750 is the ultimate high pressure demand operated drain.The unit is fully automatic -no electricity is required. Its low profile gives you the advantages of installing it in areas where the vessel to be drained is only a few inches from the ground. A unique air valve design uses a magnetic force to ensure both a positive opening and closing that will prevent air loss.The magnetic force is positioned away from the condensation level to prevent any attraction of metal particulate. An innovative ball valve support and positioning system prevents the side loading problem which otherwise would cause premature sealing failure around the valve stem. The ½” ball valve ensures that scale and rust will exit the vessel. The NA750 will not clog which eliminates the need for a strainer.
