LIFEBREATH 267 MAX Air Exchanger Greater Montreal
Is it the right size for your home?
It delivers 261 cfm net, enough to ventilate 3,100 to 4,900 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 261 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
$21.47
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 70% at 72 cfm.
Airflow and efficiency at 0 °C and −25 °C: HVI directory, Section III. Cost: 22 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.
ECMECM motor: more airflow, very low power draw
Its ECM motor delivers 267 cfm at 0.3 in of static pressure while using very little power. In a cabinet the same size as the RNC 205, that is 85 cfm more (the RNC 205 delivers 182 cfm).
DXPL03DXPL03 digital wall control included
The DXPL03 digital wall control comes in the box and is easy to program. It mounts on a wall in a central spot in the home (3-wire 20 ga cable, up to 100 ft).
70%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 72 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.
2505096Its 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.
−10 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 271 to 261 cfm. Most spec sheets show only the first number, precisely because it looks better.
22 WMeasured at the airflow it actually runs at
Its 75% at 0 °C is certified at 64 cfm, the continuous airflow of a typical home. At that setting it draws 22 W, or about 193 kWh a year.
LifetimeThe 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 and a condensate drain. It weighs 57 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. 2505096. 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.
