MODEL ER exhausts in summer and re circulates in winter. During the recircu lating cycle the butterfly dampers, which seal the opening between the roof jack collar ana sleeve section, remain in closed position and the heated air trapped at the roof line is recovered through the opening between the venturi and jet and returned to the occupied areaj thus improving the efficiency of the heating system and reducing operating costs as well as initial costs. The cycle of operation may be changed at any time through a three-position switch or ther mostat. In new design the amount of heat normally required can be greatly reduced when used in conjunction with these units. This model, with slight modifications, can also provide for sup ply of fresh air. MODEL ES either exhausts or provides for supply of fresh air merely by revers ing fan rotation through a three-posi tion switch. MODEL PRE is a typical power roof ventilator. This unit is equipped with butterfly dampers, which prevent heat loss in winter. MODEL RS recirculates or supplies: also, any proportion of recirculated and supply air may be obtained by varying the opening between the venturi and je. thru a manually, pneumatically, or elec trically-operated mechanism. Filters are optional. DELUXE MODEL ERS provides all four functions listed above. Filters are op tional. Raise the sleeve or fan section for recirculated or exhaust air and close it for supply. The sleeve or fan section is raised or lowered by: (1) gear ratio motor and rack assembly, controlled either by a three-position switch or ther mostat or (2) manual mechanism. Tms model available in sizes 31 and 38 only. NOTE: Cfm delivery of all models has been calculated on the basis of the static pressure through the unit. As the per centage of cfm delivery is reduced when fan blade rotation is reversed, specify on which cycle of operation the greater cim is required. Units having larger capaci ties or special combinations of fa blades, motor sizes and speeds are avail able on special order. 238 Air System Equipment valuator.
