The MHT-7300 High Tech Compressed Air Regulator is a high-capacity, true-diaphragm regulator for spray booths and critical refinishing operations.
FEATURES
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
Inlet/Oulet Size: 1/2 NPT
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. A water/trap filter installed upstream of the unit will protect the unit from contamination which could
lead to improper operation. 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. Install pressure gauge on open port using pipe sealing compound or tape. Installation of a supply valve (not provided)
can be used to isolate unit during servicing and adjustment.
Pressurize slowly to avoid high-pressure surge.
Open service valve (1) 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.
Regulator should be disassembled, cleaned and serviced periodically.
