Types of Ventilators, Active and passive
Active Ventilators create circulation within an attic space using either mechanical or natural principals. While passive ventilators work on an imbalance in atmospheric temperature.
Why ventilation is important –
How ventilation works – air intake starts with your soffit and circulates through
For a proper functioning attic make sure;
- Soffits are not blocked by insulation, boards or other debris
- Adequate amount of exhaust – remember intake dictates amount of exhaust – never have more exhaust then intake – 50% intake 50% exhaust
How to calculate Net free air for attic spaces – attic square footage/144/2 = square footage of intake and exhaust required

The Maximum Ventilators do not require to rotate to prevent water or snow infiltrations. Its unique storm proof system checks infiltrations while simultaneously catching the wind flow from all directions and at wind velocities as low as 6 km/hr (4 mi./hr.). With this combination of technology, wind, and pressure differentials, a “chimney or vacuum effect” results in drawing the stale air and moisture out, thus preventing moisture & heat buildup within the attic space.
For structures with restricted air intake, this product has been specifically engineered to provide the required amount of intake for a properly balanced attic.
Maximum ventilators 301,302, and 303 work on two principals, the Venturi and Bernoulli effect providing superior ventilation without the need of mechanical assistance.https://www.ventilation-maximum.com/en/sloped-roof-ventilators/
One best way to save money and the environment is to go for a solar power roof vent instead of the traditional electric version. It’s cleaner, safer, and more efficient. Solar vents have no running costs, so they eventually pay for themselves, so your only cost would be the initial purchase of the vent itself. They offer four different sizes of roof vent to fit several attic spaces. All work in ambient sunlight which means that you can be more flexible with the mounting of the panels while getting durable power from each unit than a unit that must be in direct sunlight.
Slant Back Vent is classified as a passive ventilator, and they work on reducing heat and moisture buildup that can lead to ice damming, roof deterioration, and mold infestation. It also improves airflow through the attic to manage temperature and moisture.
Classified as a passive ventilator, these vents work when there is an imbalance in temperature.
The primary purpose of an exhaust fan is to eliminate the moisture out of the bathroom. These fans help to regulate and eliminate bathroom odors. Additionally, they add to the safety of the home and its residents by decreasing fumes from cleaning agents that could possibly cause health-related issues. Bathroom exhaust fans will enhance the quality of indoor air.
Exhausts bathroom fans
These fans are used to pull excess moisture and unwanted smells out of a specific room or area. They are commonly found in kitchens, where moisture can build up due to activities such as washing, or cooking. They give ventilation to areas, decreasing chemical fume buildup and eliminating other contaminants that can be dangerous when breathed in.

These vents are set into the roof’s peak and are one of the most effective “passive” roof ventilation systems. They are created along with the continuous space on each side of the ridge cap. Hot air gathering in the attic will rise and flow outside through ridge venting. Ridge vents are almost invisible to untrained eyes. As the warmer air flows out, fresher outside air is pulled into the attic through soffit vents.
Installed along the peak of a structure allows for humid and hot air to exhaust from the apex of the roof.

For structures with restricted air intake. This product has been specifically engineered to provide the required amount of intake for a proper balanced attic
Provides continuous intake airflow at the roof's edge and provides proper intake ventilation for homes with little or no overhang.
Uses a fan to create a draw in attic space, they can be solar powered or electrically powered. Good units have a humidistat and thermostat.
