Part Number: DJK466
All new for 2013, In-O-Vate Technologies unleashed the ultra-high efficiency DryerJack series of roof vents. This new generation of roof caps is engineered with intense focus on three critical aspects: zero back pressure, denial of access to birds and rodents and duct cleaning accessible; amenities not found on any other roof termination vent in the industry.
- A damper design providing substantial defenses to bird and rodent entry
- Tuned design providing zero airflow resistance (no back pressure)
- Will meet the 2017 ICC code requiring that the passageway not diminish in size
- Duct cleaning accessible
- Small footprint and low profile "scoop" design
- A watertight extended collar for secure duct docking
- Heavy 26 gauge Galvalume® metal construction
- Nailing flange with rounded corners and 2 nail holes
- Equally suitable for new construction or retrofit installation
- Superb workmanship and pleasant eye appeal
- Available in powder coated in brown, black or white (see below)
The airflow passageway increases 63% (12.56 sq. inch opening to 20.5) through the DryerJack; this along with the curved damper provides zero inches of water column pressure in real-life testing. Note: Not recommended for use with high to medium-high profile roof tiles like Barrel, Spanish S or S-Tile.
Galvalume: A patented alloy of barrier-resistant aluminum and corrosion-fighting zinc gives Galvalume its superior corrosion resistance. Most Galvalume substrates feature an alloy that is 55% aluminum, 43.5% zinc and 1.5% silicon. Tests have proven this alloy superior to the zinc-only coating used in regular Galvanized sheeting. Additionally it is Acrylic Coated, coating designation AZ-55.
The Goose-neck style DryerJack (Model 486) provides the same zero result on back pressure but is better adapted to medium snowfall regions and sloped roofs with medium profile tiles like S and Spanish S tile.
