Air Exchanger VENMAR AVS® AI2 SERIES A180E75RT Greater Montreal
Is it the right size for your home?
It delivers 182 cfm net, enough to ventilate 2,100 to 3,400 sq ft. Choose your home's living area.
It's the right size.
For a 2,500 to 3,200 sq ft home, about 150 cfm of air needs to be renewed continuously. This unit delivers 182 cfm net — enough for the house, with extra capacity to boost ventilation for the bathroom and kitchen.
Calculation: 0.35 air changes per hour over the living volume, with 9 ft ceilings. Our estimator sets the exact airflow room by room, following CSA F326.
What it does, in numbers
$22.45
Electricity per year
Less than a 60 W light bulb
Bulbs left on day and night. Same calculation for every line: wattage × 8,760 h × 11.142 ¢/kWh.
Meets the Québec Construction Code everywhere in the province. The Code requires 54% at −25 °C below 6,000 degree-days (Montréal, Laval, Longueuil and both shores) and 60% above that. This unit is rated at 64% at 83 cfm.
Airflow and efficiency: manufacturer's data; airflow at 0.4 in and power draw from the V180E75RT spec sheet. Cost: 23 W over 8,760 h at Hydro-Québec's Rate D second tier (11.142 ¢/kWh).
What you should know about this one
Published, verifiable facts, not brochure claims.
Top onlyThe 180 cfm size comes with top ports only
The platform comes with top or side ports, but Venmar notes the 180 cfm models are only available with top ports. The 210 and 230 cfm models also come in a side-port (RS) version.
−30 cfmProtects its core membrane when ducts are too restrictive
If the maximum airflow reached during auto-balancing is 130 cfm or less, the unit takes 30 cfm off to keep the ERV core membrane from deforming under very high static pressure (over 1.3 in w.g.).
64%What it still recovers at −25 °C
The only efficiency figure that matters for a Québec winter, and the one the Code uses. An efficiency quoted without its temperature means nothing; this one is measured at a test airflow of 83 cfm.
DamperIt defrosts without depressurizing the house
In cold weather, a motorized damper closes the outdoor air intake and recirculates indoor air through the core to thaw it. The house doesn't go into negative pressure during the cycle: no cold air drawn in through leaks, and none of the imbalance manufacturers warn about when there's a fireplace or a combustion appliance.
ERVIt moves moisture too, not just heat
An ERV transfers some moisture between the two airstreams. Useful in a house that gets too dry in winter or takes on a lot of humidity in summer. The trade-off: it generally recovers less heat than a comparable HRV.
−7 cfmWhat the ducts cost it
Between a nearly unrestricted test bench (0.2 in) and a real duct system (0.4 in), it drops from 189 to 182 cfm. Most spec sheets show only the first number, precisely because it looks better.
23 WMeasured at the airflow it actually runs at
Its 81% at 0 °C is measured at 66 cfm, the continuous airflow of a typical home. At that setting it draws 23 W, or about 201 kWh a year.
5 yearsThe core warranty
The core does the work and is the most expensive part to replace. Motors and parts: 5 years. We register the warranty in your name at commissioning.
6 inWhat it needs on site
6 in ducts, top connection. It weighs 47 lb, and it needs enough clearance to slide the core out once a year.
What it needs on site
In a condo with no floor drain, or with little ceiling clearance, we usually look at a side-port model instead. Our estimator checks the location, the drain and the duct route before ordering.
