MODEL
VMAX-302-8

Adjustable sloped flashing from 2/12 to 7/12
Suggested ventilation area: 50 to 250 ft2.

Unlike the turbine, the Maximum Ventilators are CSA approved and do not require to rotate to prevent water or snow infiltrations. Its unique storm proof system prevents infiltrations while at the same time capturing 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 build-up within the attic space.

The model VMAX-302-8 has been designed for slope roof application varying from a 2/12 to 7/12 pitch. This ventilator was designed for the application on smaller roofs such as sunrooms, extensions, etc., where the aesthetics as well as efficiency is important. Has no moving parts, requires no electricity, it is completely silent and maintenance free. Built tough to endure the harshest weather conditions that nature has to offer including hail storms. It sits high enough off the roof deck to allow it to weather through snow accumulations without being covered, thus, finally giving the home owner a peace of mind.

MODEL
VMAX-401-12

Replacement head for any 12 in. round ventilator.
Adapter: Sold seperately for 10 & 14 in. units.
Suggested ventilation area: 800 to 1000ft2.

Unlike the turbine, the Maximum Ventilators are CSA approved and do not require to rotate to prevent water or snow infiltrations. Its unique storm proof system prevents infiltrations while at the same time capturing 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 build-up within the attic space.

This ventilator has been designed to replace faulty turbines of 12 in. diameters but can also replace a 10 in. or 14 in. turbines by installing an adaptor that can be ordered separately. No need of removing or replacing the shingles, allows for fast and easy installation.

MODEL
VMAX-CATHEDRAL

Special order: Custom made to the slope of the roof.
An insulated duct installed on the ridge of the roof to assure an efficent ventilation between the joists of the roof.

Ventilation Maximum designed and engineered a ventilation system in combination with the VMAX-301-12 ventilator that will allow, due to the ventilators exceptional drawing power, to draw fresh air from the soffits up between each rafter (between the insulation and underside of the roof deck) into an assembled weather tight duct system. It will then be extracted out the ventilator, thus, allowing for continuous fresh air flow throughout the attic space and preventing heat and moisture buildup from deteriorating the structural integrity of the building & its components.

Another valuable feature to this system is that it has been designed and developed to withstand the harshest weather conditions that Mother Nature could offer including hail & snow accumulations, thus, finally, giving the home owner peace of mind.

Model : Cathedral system
Storm Proof : Unique precision engineered deflector system
Solid : Built of galvanized steel
Standard Gauge : 24 & 26
