The MHT-7200 High Tech Air Compressed Air Dryer is an advanced desiccant dryer / oil removing filter with an integrated, disposable cartridge. The
unit removes water and oil vapor from compressed air for spray booths and critical refinishing operations and provides for the quickest, cleanest
cartridge change in the industry.
FEATURES
.
Combines an activated carbon inner element to remove oil vapor to >.003 ppm
with a high-capacity silica gel desiccant dryer that delivers -40°F dew point air.
Color change indicator changes from blue to pink, signaling the need to replace
cartridge. Uses (1)

Install unit in spray booth or near critical operation with at least 20 feet of supply line between unit and compressor. Failure to maintain this distance will
cause excessive water vapor to pass through unit. Unit is designed for installation in a 1/2" line; use appropriate fittings for installation in other line sizes.
Apply pipe thread compound to male thread connections. Before installing unit, relieve upstream pressure completely. Install unit level and in direction
of airflow as noted. Unit should be mounted to a rigid structure and should not be supported by the supply line.
WARNING: This product is intended for use in industrial compressed air systems only. Do not install where pressures or temperatures can
exceed those listed above.
Unit is supplied ready for use. Air tight plugs should be removed just prior to installation to ensure desiccant and activated carbon are not exposed to
air. Supply valve (not provided) can be used to isolate4 unit during servicing and should be closed when unit is not in use.
Before pressurizing, be sure bowls are turned fully clockwise. Pressurize slowly to avoid high-pressure surge.
Open service valve (1) fully so that handle is parallel to inlet pipe
Inspect daily for leaks.
Check color change indicator (2) often and replace both cartridges when indicator has turned completely pink.
Dryer should be disassembled, cleaned and serviced periodically.
