SPRINGFIELD, OHIO VENTILATING SPECIALISTS IN ALL PRINCIPAL CITIES Designed by Propellair to deliver maxi mum air with minimum horsepower. Air flow is even over all of blade--the whole fan works, not just the tips! Non-over loading--from free air to block-off, horse power is virtually constant as long as motor speed is constant. Number of blades, angle and shape, depend on use. PROPELLAIR VERTI-VENT For Roof Ventilation A fool-proof, auto matic ventilator in stalled easily on roof. Butterfly dampers, v within wind guard, \ offer virtually zero -i---------------------resistance. High velocity, vertical discharge throws heat and fumes far above the roof and prevents rain from entering when the fan is in operation. Dampers close gently and posi tively when fan coasts to a stop. 12 to 60 in. diameters, with capacities from 2100 to 68,000 cfm. I PROPELLAIR DRUM-TYPE Belt-Drive Fans for Heat, Acids, Alkalis, Fumes, Gases or Dust "CS" and "CSV" drum-type, belt-drive fans for severe, heavy-duty jobs involving elements listed for "CE" type. Sturdy, welded drum construction. Motor com pletely isolated from fan, driving belt protected in steel tube. 20 to 48 in. duct sizes, capacities 2400 to 43,000 cfm. CURVED ENTRANCE RING . An Important ' Propellair Feature' In addition to serving as a sturdy support assembly, jt reduces tip loss and enables Propellair Fans to deliver maximum air per horsepower. Introduced in 1930 as a result of exhaustive experiments and tests by Propellair engineers, this design makes possible the utilization of the "Airfoil" air-movement principle in the entrance ring as well as in the propeller. PROPELLAIR EXTENDEDSHAFT FANS For Handling Excessive Heat, Moisture, Fumes, Dust and Gases Type "CE" extended-shaft fans for severe conditions involving excessive heat, moisture, harmful fumes, explosive gases, etc.--where a motor should not operate within air stream. Drive shaft housed and sealed within steel tubing. Special formedsteel ring and support assembly. Fan sizes 12 to 60 in., capacities 2000 to 68,000 cfm. PROPELLAIR DIRECT-CONNECTED FANS For Duct, Wall or Hood, Installation Type "CD" directconnected fans for wide range of jobs, from free air conditions such as window or panel mquntings, to instal lation in roof ventilators, hoods, or duct work involving medium to relatively high resistance. Successful whenever a motor can operate directly' within air stream. Sizes 12 to 60 in., capacities 800 to 85,000 cfm. 991
