About the NET.Pro+ Energy Recovery Ventilator Mair ERV Exchange Core
The heart of the NET.Pro+ Energy Recovery Ventilator is the Mair ERV Exchange Core, which uses nanotechnology technology to enable the transfer of heat as well as moisture into and out of your home.
This means:
In the summer, the ERV uses the stale, conditioned indoor air you’re expelling to cool the incoming hot air.
In the winter, the ERV uses the stale, heated indoor air you’re expelling to preheat the incoming cold air.

FAQs

How does an ERV fit into the MENRED Wuheng Climate System? How does an ERV fit into the MENRED Wuheng Climate System?

The MENRED Wuheng Climate System takes an integrated approach to indoor climate by coordinating temperature control, humidity management, fresh air, cleanliness, and quietness.

Can an ERV work with radiant heating and cooling? Can an ERV work with radiant heating and cooling?

Yes. An ERV can work alongside radiant heating and cooling as part of an integrated indoor climate system.

How often should an ERV be serviced? How often should an ERV be serviced?

Routine maintenance generally includes checking filters, inspecting the heat or enthalpy exchange core, checking fans and accessible air passages, and verifying that supply and exhaust airflow remain appropriate.

How often should ERV filters be replaced? How often should ERV filters be replaced?

Filter maintenance intervals depend on the filter type, outdoor air quality, operating hours, and the manufacturer's instructions.

Can an ERV be installed in an existing home? Can an ERV be installed in an existing home?

Yes. Depending on the building layout and the selected model, an ERV may be suitable for retrofit projects as well as new construction.

Is an ERV noisy? Is an ERV noisy?

ERVs contain fans and moving air, so some operating noise is unavoidable. The perceived noise depends on fan speed, unit design, installation quality, duct sizing, airflow velocity, vibration isolation, and the location of the unit.

Where should an ERV be installed? Where should an ERV be installed?

The installation location depends on the ERV model, building layout, duct routing, outdoor air intake and exhaust locations, and access requirements.

How do I choose the right ERV for my home? How do I choose the right ERV for my home?

Start with the required ventilation airflow, then evaluate the unit's delivered airflow at the planned external static pressure, recovery performance, filtration, sound levels, dimensions, power consumption, controls, and maintenance access.

Does an ERV provide clean air without opening windows? Does an ERV provide clean air without opening windows?

An ERV can provide a controlled supply of outdoor air while reducing the need to open windows solely for ventilation.

Can an ERV remove PM2.5, dust, and pollen? Can an ERV remove PM2.5, dust, and pollen?

An ERV can reduce incoming airborne particles when equipped with suitable filters. Its effectiveness depends on the filter's tested efficiency, the particle size, sealing, airflow, and filter maintenance.

Can an ERV reduce indoor CO₂ levels? Can an ERV reduce indoor CO₂ levels?

An ERV can help reduce indoor carbon dioxide (CO₂) concentrations by replacing CO₂-rich indoor air with outdoor air, provided that the outdoor airflow and air distribution are adequate for the occupancy.

How much fresh air does a home need? How much fresh air does a home need?

Required outdoor airflow depends on the applicable building code, occupancy, floor area, room use, and the ventilation design standard used for the project.

Is an ERV suitable for hot and humid climates? Is an ERV suitable for hot and humid climates?

An ERV can be part of a ventilation strategy for hot and humid climates, but the design must account for both heat and moisture loads.

Does an ERV work in both summer and winter? Does an ERV work in both summer and winter?

Yes. An appropriately designed ERV can operate in both heating and cooling seasons.

Can an ERV control indoor humidity? Can an ERV control indoor humidity?

An ERV with an enthalpy exchange core can transfer moisture between incoming and outgoing air streams. This may help moderate indoor humidity, but it does not actively remove moisture in the same way as a dedicated dehumidifier.

Does an ERV save energy? Does an ERV save energy?

An ERV can reduce the energy required to condition outdoor ventilation air by recovering part of the heat and, where applicable, moisture from the exhaust air.

What is the difference between an ERV and a standard exhaust fan? What is the difference between an ERV and a standard exhaust fan?

A standard exhaust fan removes indoor air but does not normally recover energy from it. Replacement outdoor air must enter through designed inlets or other openings, and its temperature and moisture can add to the building's heating or cooling load.

What is the difference between an ERV and an HRV? What is the difference between an ERV and an HRV?

An HRV (Heat Recovery Ventilator) primarily transfers sensible heat between incoming and outgoing air. An ERV (Energy Recovery Ventilator) can transfer sensible heat and moisture when equipped with an enthalpy exchange core.

How does an ERV system work How does an ERV system work

An ERV draws outdoor air into the building and exhausts stale indoor air through separate air passages. Inside the energy recovery core, heat and moisture can transfer between the two air streams without intentionally mixing the bulk air streams.

What is an Energy Recovery Ventilator (ERV)? What is an Energy Recovery Ventilator (ERV)?

An Energy Recovery Ventilator (ERV) is a mechanical ventilation system that supplies outdoor air and exhausts stale indoor air while transferring heat and, in enthalpy recovery systems, moisture between the two air streams.

What is the difference between an ERV and a dehumidifier? What is the difference between an ERV and a dehumidifier?

An ERV primarily provides controlled ventilation and energy recovery. A dehumidifier primarily removes moisture from indoor air.

Can an ERV control indoor humidity? Can an ERV control indoor humidity?

An ERV can transfer moisture between incoming and outgoing air depending on its core technology and operating conditions.

How enthalpy exchanger works? How enthalpy exchanger works?

By recovering and reusing the energy from the exhaust air, enthalpy exchangers effectively reduce the energy demand of the HVAC system, improve indoor air quality, and enhance overall energy efficiency in buildings.

what is an enthalpy exchanger what is an enthalpy exchanger

Enthalpy exchangers are particularly useful in climates where there are significant temperature and humidity differences between the indoor and outdoor environments. Apart from transferring sensible heat (temperature), they also transfer latent heat (moisture) between the airstreams, providing the benefits of both heat and moisture recovery.
