Air Exchanger VENMAR AVS® E15 SERIES 43911 Greater Montreal
Is it the right size for your home?
It delivers 140 cfm net, enough to ventilate 1,600 to 2,600 sq ft. Choose your home's living area.
It's the right size.
For a 1,500 to 2,500 sq ft home, about 105 cfm of air needs to be renewed continuously. This unit delivers 140 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
$29.28
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 60% at 70 cfm.
Airflow and efficiency: manufacturer's published data. Cost: 30 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.
5 rangesFive speed ranges from 40 to 140 cfm
The installer picks one of five airflow ranges, from 40–80 cfm up to 85–140 cfm (factory set 55–125 cfm; maximums rated at 0.4 in). One unit can thus suit a small dwelling as well as a mid-size home.
ECMTwo ECM motors: 90 W maximum
Supply and exhaust each run on their own electronically commutated (ECM) motor. Rated draw on the sheet: 1.3 A and 90 W maximum; at 52 cfm the measured draw is only 24 W.
60%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 70 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.
−17 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 157 to 140 cfm. Most spec sheets show only the first number, precisely because it looks better.
30 WMeasured at the airflow it actually runs at
Its 67% at 0 °C is measured at 65 cfm, the continuous airflow of a typical home. At that setting it draws 30 W, or about 263 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 (oval) ducts, top connection. It weighs 65 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.

Unparalleled Efficiency: VENMAR AVS E15 ECM ERV 43911
As AirGreen, an HVAC specialist based in Montreal, we pride ourselves on offering top-tier HVAC sales and installation services all over Greater Montreal, Laval, Longueuil, South Shore, and North Shore. We have curated a dedicated Air Exchanger section on our website featuring a range of Venmar Air Exchangers. One exceptional product from this selection is the VENMAR AVS E15 ECM ERV 43911.
The VENMAR AVS E15 ECM ERV 43911 is a flagship offering from Venmar, setting new benchmarks in innovative design and energy efficiency. Equipped with high-performance motors that operate at a power equivalent to a compact fluorescent bulb (13.5 watts each), the E15 ECM ERV substantially lowers energy costs without any compromise on performance.
In addition, the E15 ECM ERV's advanced core not only absorbs heat but also moisture from the air streams passing through it, without any intermixing. This two-pronged functionality is particularly useful in summer when the indoor heat and humidity are transferred to the exhaust air stream, keeping your interiors cool. During winters, this process reverses, ensuring your home remains warm and comfortable.
This balanced system, ideal for small to mid-sized homes, promises superior indoor air quality. Paired with the state-of-the-art programmable Altitude wall control, the E15 ECM ERV surpasses energy-saving standards while effectively providing heat recovery and ventilation.
