The DIRECT AIR space at AirGreenSold and installed by AirGreen
DIRECT AIR × AirGreen · Air exchangers
DIRECT AIR air exchangers: eight units, from the condo to the large house.
Seven HRVs and one ERV, from 59 to 203 CFM at 0.4 in. wc of static pressure per the HVI directory. What sets them apart: airflow, recovery in deep cold, recirculation, and where they go. Here are the figures side by side, and a tool to choose.
8exchangers: 7 HRVs, 1 ERV
59–203CFM at 0.4 in. wc (HVI)
80%sensible recovery at 0 °C, HE series (HVI)
Lifetimelimited warranty on HRV cores (brochure)
Three families
With recirculation, without recirculation, or energy recovery.
An HRV recovers heat from the exhaust air; an ERV also recovers part of its moisture. Recirculation moves the house air around without exhausting it.
HRV with recirculation
PHRVR 120HE · 150HE · 200HE · PHRVR70 ES · PHRVR 104
- HE series: up to 81% sensible heat recovery, counterflow hexagonal core, compatible with IAQ controls
- Recirculation defrost and recirculation mode
- ENERGY STAR and Novoclimat 2.0: HE series and PHRVR70 ES
- PHRVR 104: bathroom turbo mode
HRV without recirculation
PHRV 96 · PHRV 140
- Aluminum recovery core, automatic defrost
- PHRV 96: designed for condos, 4 in. round ports
- PHRV 140: designed for single-family homes, 6 in. oval ports
ERV (energy recovery)
PVRE 70
- Water-permeable, frost-tolerant core: it also recovers moisture, up to 45% (latent)
- Ceiling or wall mount, bracket included; no drain needed (spec sheet)
- Only 9.75 in. thick (spec sheet), for the condo with no mechanical room

The choice
Tick your constraints: we keep the exchangers that meet them.
Ranking is by recovery at −25 °C, the one that matters in a cold snap.

The figures
Eight exchangers, the same measurements, side by side.
Airflow at 0.4 in. wc of static pressure, sensible recovery at 0 °C and power at the test flow: HVI directory. Maximum recovery at −25 °C, ports and dimensions: Direct Air brochure.

Questions
What people ask us, and what the sources say.
HRV or ERV: which one?
An HRV recovers heat from the exhaust air; an ERV, like the PVRE 70, also recovers part of the moisture (up to 45% at 0 °C per its spec sheet). In a house where the air gets very dry in winter, the ERV keeps more moisture; elsewhere, an HRV is enough.
What airflow does my house need?
The ventilation airflow is calculated for the house and the applicable code. We calculate it during the visit, then choose an exchanger whose airflow at 0.4 in. wc covers that need.
What is the warranty on DIRECT AIR exchangers?
Per the brochure: HRV cores for life (limited warranty), ERV cores 5 years, sealed motors 7 years (limited warranty), other parts 5 years, controls 2 years; filters are not covered.
Which ones are ENERGY STAR and Novoclimat 2.0?
The HE series (PHRVR 120HE, 150HE and 200HE) and the PHRVR70 ES, per the brochure.
Why does the PVRE 70 have no HVI figures?
It is not in the HVI directory we consulted. So we give the values from its spec sheet: 70 CFM at 0.4 in. wc, 70% sensible recovery at 0 °C (at 51 CFM) and 34% at −25 °C.
AirGreen × DIRECT AIR
Your air exchanger, chosen for your home and installed by AirGreen.
We calculate the required airflow, look at where the ducts and drain can go, then choose the exchanger and its control. The quote shows the exact model.
