Air Exchanger VENMAR AVS® AI2 SERIES A210E75RS Greater Montreal
Is it the right size for your home?
It delivers 206 cfm net, enough to ventilate 2,400 to 3,900 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 206 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
$27.33
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 65% at 83 cfm.
Airflow and efficiency: manufacturer's data; airflow at 0.4 in and power draw from the V210E75RS spec sheet. Cost: 28 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.
19.5 inSide ports: 19.5 in tall, 27.13 in wide
The RS version keeps the A210E75RT's published performance, but its 6 in collars exit on the side: the cabinet is 19.5 in tall and 27.13 in wide, versus 21.69 by 24.81 in for the top-port version.
8 in8 in ducts advised above 200 cfm
Venmar recommends 8 in instead of 6 in ducting when the required airflow is over 200 cfm with long runs or many elbows. 6-to-8 in transitions then go on the ports, secured with duct tape only.
65%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.
−4 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 210 to 206 cfm. Most spec sheets show only the first number, precisely because it looks better.
28 WMeasured at the airflow it actually runs at
Its 81% at 0 °C is measured at 64 cfm, the continuous airflow of a typical home. At that setting it draws 28 W, or about 245 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, side 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.
