Application
The Macurco DMK-1 is an air tight enclosure that provides a means to mount any Macurco gas detector to an air
duct. By duct mounting a Macurco gas detector it can monitor the air inside of the duct and provide early detection
of carbon monoxide or other gases moving through the HVAC system. The DMK-1 used with Macurco gas detectors
can provide automatic control to prevent recirculation of these gases into additional areas by the air handling
systems, fans and blowers in commercial and residential applications.
