Class II Fans offer quiet operation.

QEI Class II fans provide static pressure capability from 4.0 to more than 8.0 in. wc, making them suitable for supply air applications. They use mixed flow inline design to combine efficiency of vane axial fan with quietness of centrifugal fan. Blades are specifically pitched to handle high pressures. All QEI fans are AMCA licensed for sound and air performance.

Energy Recovery Ventilator recovers 80% of energy.

Model ERH recovers energy from exhaust air and transfers it to supply air stream, substantially reducing energy costs. It provides airflow from 1,000 to 10,000 cfm, with static pressure capabilities up to 2.0 in. Heating options include indirect gas, hot water coil or electric coil. Because it handles heat tempering only, it is smaller and more economical than units that can also handle cooling.

Fan is quiet enough for libraries.

QEI mixed flow fan comes with Sound Vault Housing that is lined with 2 in. of sound-attenuating insulation, integral isolators, and flexible connections to lock-in radiated sound and minimize vibration transmission. Housing reduces radiated sound levels by more than 50%, making it suitable for fans located adjacent to occupied workspace. Applications include office buildings, libraries, or...

Make-Up Air Unit is direct gas-fired.

Part of X-series modular make-up air units, Model DGX direct gas-fired unit provides heated make-up air to commercial and industrial facilities. It is available with various housing sizes and capacities to 23,000 cfm. It also offers mechanical and evaporative cooling capacities, as well as industrial space heating capabilities.

Make-Up Air Supply has flexible, modular construction.

Model MSX is suitable for make-up air applications where gas-fired heating is not desired. Coil heating and/or cooling tempering options are available, or unit may be used for untempered applications. MSX provides 15,000 cfm capacity (max), mechanical and evaporative cooling capacities, and mixing box capabilities.
