Flat Roof Ventilators

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.

Filtre média - Ventilation Maximum

Media filter

Used for snow infiltration applications, the media filter is available for residential, commercial, and industrial ventilators. When applied to the ventilator, please consider a 20% efficiency reduction from the specified ventilator specifications.

Bassin

Retention pan

Often use with the media filter. The polypropilen retention pan is constructed of galvanized steel and includes 4 metal straps, one on each corner, for easy installation. Available Colours: Black, Brown, and Grey.

MODEL VMAX-102-12 

Deflectors: 1 Base: 45 degree cant. Height : 23 1/4 in. Ventilation area: 100 to 150 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.

This model has been designed to be installed onto a wooden curb. The thickness of the wooden curb in conjunction with the thickness of the roofing membrane will determine the size of the ventilator required. The interior dimension of the wood curb should equal to the opening in the deck to allow for unobstructed air flow. The suggested roof area for one (1) ventilator model VMAX-102-12 has been calculated based on a 10 in. x 10 in. opening or (hole) of curb and roof deck.
Model : VMAX-102-12
Deflectors : 1
Net Free Evacuation : 96 in.2
Suggested Ventilation Area : 100 to 150 ft.2
Tested Extraction Rate : 134 CFM
Base Flashing : 45 degree cant flashing
Storm Proof : Unique precision engineered deflector system
Solid : Built of structural galvanized steel
Standard Gauge : 24 & 26
Rodent Proof : Built-in galvanized wire mesh screen
Finish : Interior and exterior powder coated polyester baked paint with UV protection
Warranty : Limited Lifetime Warranty on all manufacturing defects, 5 years on paint & corrosion
