Lomanco manufactures a range of static roof vents, with the 750 series being a prominent offering. These vents are designed for residential roof ventilation and are available in several variations to accommodate different roofing materials and installation needs. The 750 series includes models designed to prevent roof discoloration, provide enhanced weather protection, and facilitate installation on various roof pitches. A lifetime limited warranty is offered on certain 750 series models.
Lomanco 750 Series Overview
The Lomanco 750 series consists of several models, each with specific features. The original 750 Slant Back vent is frequently imitated but remains a core product. The series also includes the 750-GES, 750-S, 770, 770-S, 770-D, and 770-DS. The 730 is described as a smaller version of the 750 and is included in the EVA Combo vent package, while the 750-E features an extended flange size. The 770 is a larger version of the 750, and the 770-D and 770-DS are twin 770 vents designed for off-ridge installation. The 750-GES and 750-S models utilize heavy-duty galvanized steel construction for enhanced weather protection.
Installation Considerations
Lomanco Static Roof Vents, including the 750 series, are designed for relatively easy installation. They feature a large nailing flange to simplify the process. The Slant Back vents are specifically designed to be installed on roofs with any pitch. Installation instructions for specific models, such as the LomanCool 2000TH, Omni Solar Gable Vent, PCV1, and Whirlybird BEB, are available separately. The 600-S and 550-S models include a tall throat to accommodate air circulation on shake roofs after shake installation.
Materials and Construction
The Lomanco 750 series vents are available in aluminum and galvanized steel. The 750 vent is also available in copper. Other Lomanco vents utilize various materials, including plastic and galvanized steel. The 550 PRO model features a one-piece molded plastic collar combined with aluminum top and bottom construction. The P60 PRO model is constructed from impact-resistant polypropylene, designed to resist denting, cracking, and degradation from UV exposure. This polypropylene material has been used in Lomanco’s Omni Series Ridge Vents for over 20 years.
Weather Protection Features
Several features contribute to the weather protection offered by Lomanco vents. The 750-GES, 750-S, 770-S, and 770-DS models provide enhanced weather protection. The 550 PRO includes a flange on the vent stack for superior weather protection. The 135 series features an 8x8 aluminum screen and a weather-shielding rain guard. The P60 PRO incorporates an 18x16 mesh screen for enhanced weather protection.
