Air Exchanger VENMAR AVS® S SERIES 41700 Greater Montreal
Is it the right size for your home?
It delivers 102 cfm net, enough to ventilate 1,200 to 1,900 sq ft. Choose your home's living area.
It's the right size.
For a 900 to 1,500 sq ft home, about 63 cfm of air needs to be renewed continuously. This unit delivers 102 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
$39.04
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.
Below the Code threshold for a new home. 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 46% at 51 cfm. The requirement applies to new buildings and major renovations: for a replacement, talk to us about your project before choosing.
Airflow and efficiency at 0 °C and −25 °C: HVI directory, Section III. Cost: 40 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.
9 in9 in cabinet designed for the ceiling
Horizontal installation only, under a ceiling or inside a dropped ceiling. The built-in anti-vibration device limits noise transmission, even when the unit is fastened directly to a concrete ceiling.
ColdShieldColdShield guards against freezing supply air
If the air supplied to the home drops below freezing (abnormal conditions), the unit first adds defrost time, then switches to protection mode and stops supplying the home, to avoid blowing ice-cold air into the rooms.
46%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 51 cfm.
ExhaustIt defrosts by pausing the fresh air for a few minutes
In cold weather, the supply fan stops for a few minutes while the exhaust keeps running, so warm indoor air thaws the core. During the cycle the house is briefly under negative pressure; if you have a fireplace or a naturally vented combustion appliance, mention it to our estimator.
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.
2005001Its HVI certification number
Listed in Section III of the Home Ventilating Institute's certified products directory. Anyone can check it, and it's the first condition for the Rénoclimat grant.
−6 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 108 to 102 cfm. Most spec sheets show only the first number, precisely because it looks better.
40 WMeasured at the airflow it actually runs at
Its 66% at 0 °C is certified at 49 cfm, the continuous airflow of a typical home. At that setting it draws 40 W, or about 350 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.
5 inWhat it needs on site
5 in ducts, side connection. It weighs 32 lb, and it needs enough clearance to slide the core out once a year.
Rénoclimat: $500 to install or replace an HRV or ERV
First condition met: HVI Section III certified, No. 2005001. Second: your EnerGuide rating must improve between the two evaluations. Québec warns that an air exchanger installed on its own can increase a home's energy use; that's why we balance it to the calculated airflow rather than running it at full speed.
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.

The VENMAR AVS® S SERIES™ ERV 108 CFM 65% SRE SIDE PORTS 41700, commonly known as the S10 ERV, is your perfect choice for condominiums, and other residential units. Capable of delivering an airflow rate up to 108 CFM, the S10 ERV presents an unbeatable combination of compact design and unmatched energy efficiency.
Compact Design for Easy Installation
With a thickness of merely nine inches, the S10 ERV installs effortlessly in the ceiling of any living unit. Despite its compactness, it provides a cost-effective solution that does not compromise on performance.
Advanced Blower Design
The S10 ERV features an advanced blower design that significantly reduces the noise generated from air displacement in the ERV. Additionally, its integrated anti-vibration installation system eliminates noise associated with installation directly onto concrete ceilings, ensuring a quiet, peaceful indoor environment.
Convenient and Quick Installation
The S10 ERV promises an easy and fast in-ceiling installation with its innovative snap-fit brackets and an ingenious snap-in hooking system. These features greatly reduce installation time, while the robust, 100% metal components cater to rigorous jobsite conditions.
MERV 8 Filtration Option
For those seeking a higher degree of air purity, the S10 ERV offers an optional MERV 8 filtration.
ColdShield™ Cold Protection System
A remarkable feature of the S10 ERV is its ColdShield™ cold protection system. This advanced system ensures that supply air is tempered even under extremely cold conditions, which protects the equipment. Furthermore, this technology requires no drain, simplifying the installation process.
Warranty
To provide you with peace of mind, the S10 ERV comes with a 5-year warranty on parts, with the original proof of purchase.
Superior Construction
The S10 ERV showcases exceptional construction with its galvanized steel housing and door. The one-piece molded insulation shell, made of expanded polystyrene (UL 94 HF-1 certified), ensures superior insulation. Additionally, it features galvanized steel 5" diameter ports*, steel door hinges and latches, and cold side ports with a plastic ring that allows vapor barrier sealing. All these attributes contribute to the unit's durability and high performance. It does not require a drain, further easing the installation process.
(*Please note, all unit ports are created to be connected to ducts having a minimum of 5” diameter. However, they can be connected to larger sized ducts using an appropriate transition, e.g., a 5” diameter to 6” diameter transition.)
Reliable Motors
The S10 ERV is powered by two high-reliability, external rotor PSC motors, which are totally enclosed and thermally protected. These backward blowers are designed to support high static pressure environments.
ERV Core
The heart of the S10 ERV is its crossflow aluminum-polymerized paper core. This UL723 certified core leverages hydroscopic polymer exchange water by direct vapor transfer, using molecular transport without the need for condensation. It's constructed of alternate layers of corrugated aluminum material and polymeric bactericide dessiccant impregnated media, which do not promote the growth of mold or bacteria.
Controls
The S10 ERV comes equipped with an integrated push-button control for low or high-speed operation. The LED indicator shows operating modes and error codes. The unit must be permanently energized, meaning no control should be installed on the power supply of the unit.
Defrost Cycles
The unit operation includes a choice of regular or extended defrost cycles, according to climatic conditions. The unit is equipped with Coldshield™ protection to stop air supply in the dwelling if the air supply temperature drops below the freezing point due to abnormal conditions.
Air Flow Balancing
Unit door is equipped with pressure taps and a balancing chart to allow verification of balancing of the ERV unit. Balancing dampers are integrated into cold supply and cold exhaust ports.
Compliance with Standards
The S10 ERV is certified as per CSA C439 Standards. It's certified to UL 1812 safety standard for ducted heat recovery ventilators, to CSA C22.2 No. 113 safety standard for fans and ventilators, and it complies with CSA C444 requirements regulating the installation of Energy Recovery Ventilators.
