The MHT-7000 High Tech Air Preparation System is an advanced air for spray booths and critical refinishing operations. The system offers Six Stages
of air preparation in a single unit and provides for the quickest, cleanest cartridge change in the industry.
FEATURES
MHT-7100
High-volume water trap combined with a hydrophilic depth cartridge
that removes particulates, oil and water aerosols. Overnight drain valve drains
accumulated moisture when pressure is off. Uses (1)
M-710
drop-in replacement
cartridge.
MHT-7200
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)
M-720
drop-in replacement cartridge.
MHT-7300
High-capacity, true diaphragm regulator designed to set and hold
pressure over a wide range of flows and conditions. High-visibility, multi-scale
pressure gauge features a scratch and solvent resistant glass lens. Large,
ergonomic adjustment knob locks to hold pressure setting.
SPECIFICATIONS
Nominal Airflow Rating:
30 SCFM
Maximum Inlet Pressure:
125 PSIG
Outlet Pressure Range:
2-125 PSI
Operating Temperature Range: 40-120 °F
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 (1) should be closed when unit is not in use.
A 1/4” ID flexible drain hose may be connected to overnight drain valve (3) and routed to an approved drain to prevent water accumulation in work area.
Before pressurizing, be sure bowls are turned fully clockwise. Pressurize slowly to avoid high-pressure surge.
Open service valve (2) fully so that handle is parallel to inlet pipe. Turn knob on regulator clockwise to increase air pressure, counter-clockwise to
decrease. To reduce pressure setting, first reduce pressure to a setting lower than desired, then increase to the desired setting. Push knob up firmly to
lock and prevent accidental adjustment.
Inspect daily for leaks.
Check drain by shutting off supply pressure and relieving downstream pressure. Accumulated liquid should drip slowly from drain.
