FANTECH SHR 3205RD Air Exchanger Greater Montreal
Is it the right size for your home?
It delivers 267 cfm net, enough to ventilate 3,200 to 5,000 sq ft. Choose your home's living area.
It's the right size.
For a 3,200 to 5,000 sq ft home, about 215 cfm of air needs to be renewed continuously. This unit delivers 267 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
$132.74
Electricity per year
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 67% at 123 cfm.
Airflow and efficiency: manufacturer's published data. Cost: 136 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.
2 sidesAccess doors on both sides of the cabinet
The SHR 3205RD has access doors on two sides, allowing several installation layouts and easier service. The core slides on improved guide channels and comes out with only 14 in of clearance.
2 coresTwo cores and four fans for large volumes
With four fans, two aluminum cores and 8 in connections, Fantech intends it for very large homes or small commercial buildings. Its sheet lists 267 cfm at 0.4 in.
67%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 123 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.
HRVIt recovers heat, not moisture
Excess moisture leaves the house. In Québec, that's the right choice in most cases: in winter, the problem is almost always too much humidity, not too little.
136 WMeasured at the airflow it actually runs at
Its 66% at 0 °C is measured at 118 cfm, the continuous airflow of a typical home. At that setting it draws 136 W, or about 1191 kWh a year.
LifetimeThe core warranty
The core does the work and is the most expensive part to replace. Motors: 7 years. Parts: 5 years. We register the warranty in your name at commissioning.
8 inWhat it needs on site
8 in ducts, side connection and a condensate drain. It weighs 80 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.

Introducing the Fantech SHR 3205RD Heat Exchanger
AirGreen is a top-tier HVAC company located in Montreal. We specialize in selling and installing Air Exchangers. In our product lineup, we're proud to feature the Fantech SHR 3205RD Heat Recovery Ventilator (HRV). This particular product is ideal for larger residential or small commercial applications, thanks to its compact design and high efficiency.
Premium Efficiency with the Fantech SHR 3205RD
The SHR 3205RD is designed for superior energy efficiency and improved indoor air quality. Its design is perfect for applications that require high static pressure and high airflow. The unit ensures a constant supply of fresh air into a space while exhausting an equivalent amount of stale air. During winter months, the heat from the outgoing air is transferred to the fresh incoming air, resulting in energy savings. In summer, if the building has an air cooling system, the incoming air is pre-cooled. The SHR 3205RD is equipped with automatic defrost mechanisms to ensure year-round use.
Unbeatable Features of the SHR 3205RD
The Fantech SHR 3205RD is packed with numerous features to provide top-notch ventilation and energy efficiency.
Compact Design and Versatile Installation
The SHR 3205RD features a compact design, making it suitable for various installation scenarios. Access panels on both sides of the unit offer installation versatility and facilitate servicing.
High-Performance Motors
The unit includes four factory-balanced fans with backward-curved blades. These fans are powered by motors with permanently lubricated, sealed ball bearings that ensure long life and maintenance-free operation.
Advanced Heat Recovery Core
The SHR 3205RD has two aluminum heat recovery cores, designed for efficient cross-flow ventilation. Despite their compact dimensions, these cores offer superior heat transfer performance, ensuring optimal indoor temperature regulation.
Effective Defrost Mechanism
During the defrost sequence, a motorized damper temporarily blocks the incoming fresh air stream. The warm air from the interior can then circulate through the HRV, ensuring effective defrosting without the risk of negative pressure or the intrusion of household odors from the kitchen or bathroom.
Superior Serviceability
The core, filters, fans, drain pan, and electrical panel can be accessed easily through an access panel. The core can slide out conveniently with only 14” (356 mm) clearance, simplifying maintenance and servicing.
Durable Casing
The casing of the SHR 3205RD is made from 24-gauge galvanized steel and features a baked powder-coated paint finish for additional durability and resistance to corrosion.
High-Quality Insulation
The SHR 3205RD is fully insulated with 1” (25 mm) high-density expanded polystyrene. This insulation enhances the thermal performance of the unit, contributing to overall energy efficiency.
Efficient Filtration
The unit comes with four washable electrostatic panel-type air filters. These filters effectively remove airborne particles, improving indoor air quality and can be washed and reused multiple times.
User-friendly Controls
The SHR 3205RD features an external three-position (Low/Stand By/Medium) rocker switch for continuous ventilation. Fantech also offers a variety of external controls for greater flexibility and control over ventilation levels.
Comprehensive Warranty
The Fantech SHR 3205RD is backed by a comprehensive warranty – a limited lifetime warranty on the aluminum core, a 7-year warranty on the motors, and a 5-year warranty on other parts.
In summary, the Fantech SHR 3205RD HRV is an exceptional solution for maintaining excellent indoor air quality and energy efficiency in larger residential or small commercial buildings.
