Tpi Ce 24-DS Direct Drive Exhaust Fan 0.25 Hp 24 Inch

Product Description

The TPI CE 24-DS is a totally enclosed, direct drive exhaust fan built for continuous ventilation in demanding commercial and industrial environments. Powered by a 0.25 HP motor running on 120 volts single phase, it moves up to 3,400 CFM at high speed and 2,770 CFM at low speed. The 24-inch blade and totally enclosed motor construction make this unit suitable for locations where airborne contaminants, dust, or moisture could damage an open-frame motor. Licensed HVAC technicians and ventilation contractors typically specify this fan for wall or ceiling exhaust applications where reliable, sustained airflow is required.

The CE 24-DS fits standard rough openings of 27.125 inches height by 27.125 inches width. Its direct drive design eliminates belt and pulley maintenance, reducing long-term service time. The two-speed operation gives installing technicians and building operators control over airflow volume to match varying ventilation loads. Typical installations include manufacturing facilities, warehouses, equipment rooms, and other commercial spaces requiring code-compliant mechanical exhaust.

Compatibility

Designed as an OEM-style direct drive exhaust fan replacement or new installation for commercial and industrial wall exhaust applications requiring a 24-inch blade and a 27.125-inch by 27.125-inch rough opening.

Installation Notes

Installation should be performed by a licensed HVAC or mechanical contractor in accordance with local mechanical codes and ASHRAE ventilation standards. Disconnect and lock out all electrical power before mounting, wiring, or servicing the unit. The rough opening framing should be verified to match the 27.125-inch by 27.125-inch requirement before mounting. Refer to the manufacturer wiring diagram for proper two-speed motor connections and confirm circuit ampacity against the 2.5-amp draw.
