Double L's DIrectAire 4413 reduces heating costs and bird drafting. Its phenomenal curved blade throws air to center of house for optimal mixing, especially in wider poultry houses. The DirectAire 4413 poultry sidewall inlet channels fresh air to the ceiling peak , even in wider houses to reduce or eliminate bird drafting and save heating costs. The 4413 delivers significantly more CFM than conventional metal inlets and reduces the number of inlets needed. Double L's Direct Aire 4413 is rodent and corrosion resistant as well as insulated and fully sealed against air leakage. Its superior sealing and airflow mean superior value.
