500 CFM Energy Recovery Ventilators (ERV)

A 1,200-square-foot home should not be sized from floor area alone. The required ERV airflow depends on occupancy, outdoor-air requirements, airtightness, room-by-room needs, and exhaust strategy. The product information provided is focused on a 500 CFM unitary ERV system for commercial, light commercial, and industrial applications, so residential sizing should be confirmed through a dedicated HVAC design.

An ERV transfers heat and also helps exchange moisture between outgoing and incoming air, while an HRV primarily transfers sensible heat. An ERV can be advantageous where managing indoor humidity and maintaining balanced ventilation are important. The appropriate choice depends on the building, climate, ventilation loads, and indoor-air-quality objectives; a designer should evaluate the complete HVAC system before specifying either technology.

The 500 CFM ERV category is suited to commercial office buildings, light commercial spaces, industrial facilities, machine shops, HVAC retrofits, and new installations requiring fresh-air intake and exhaust-air heat recovery. The system can be configured with separate in-line fans and filter boxes, allowing designers and contractors to coordinate the ERV with the broader ventilation arrangement.

The direct counter-flow heat exchanger is specified with 70–90%+ thermal efficiency, depending on the configuration and operating conditions. Actual project performance can vary with airflow, temperature conditions, controls, duct arrangement, and maintenance. Equipment selection should therefore consider the complete design rather than relying on a single efficiency figure in isolation.

Yes. The product information identifies HVAC system retrofits and new installations as applications. The stackable modular design, lightweight and man-portable construction, low-static-pressure operation, and ability to fit through a 36-inch door can help address access and installation constraints. Final suitability depends on the available space, ductwork, airflow requirements, and project-specific mechanical design.

The unitary ERV systems use galvanized steel construction and are factory-wired and field-tested. Their modular design allows units to be stacked, while compatibility with separate in-line fans and filter boxes supports flexible system planning. Installation teams should confirm access, support, duct connections, controls, and operating conditions during equipment selection and project coordination.
