SKU CH-3E5C-SRHE4

Double-inlet forward-curved belt-drive blower delivers 2,100–5,270 cfm at up to 1 1/2 in wc static pressure

  • typeDouble Inlet Forward Curve, Belt Drive, Less Motor
  • Double inlet design moves more air per rotation
  • Belt drive allows flexible motor placement and speed control

  • Ball bearings reduce friction for quieter, longer operation
  • Airflow range from 2 100 to 5 270 cfm suits varied ventilation needs

Double Inlet Forward Curve Blower

This Dayton blower uses a double inlet forward curve wheel to move air through belt drive operation. The unit arrives unassembled without a motor so the installer selects a matching drive package. Steel housing and steel wheel construction suit industrial ventilation and air handling installations.

Installers needing a 12 3/4 inch wheel diameter

This blower suits projects that specify a 12 3/4 inch forward curved wheel with belt drive and ball bearings. Buyers who want a complete motorised unit or a direct drive configuration should look at something else. The unassembled state also means it is not for installers who need a ready to mount assembly.

12 3/4 inch wheel diameter and belt drive

The wheel diameter of 12 3/4 inches combined with belt drive determines whether this blower fits the ductwork and drive layout. Airflow ranges from 2 100 cfm to 5 270 cfm with a maximum static pressure of 1 1/2 in wc. Inlet diameter is 10 1/8 inches and outlet height is 13 3/8 inches.

Questions about this item

What belt maintenance will the 1 in shaft and ball bearings need over time?

The 1 in shaft runs on ball bearings that should be lubricated periodically and the belt tension checked regularly to prevent slippage on the forward-curved wheel.

What airflow limit appears first when the blower runs continuously at 5,270 cfm and 1 1/2 in wc static pressure?

The 1 1/2 in wc maximum static pressure is reached before the 5,270 cfm airflow ceiling, so duct resistance will limit output first.

How much heat does the steel housing add to the airstream when inlet air reaches 150 Degrees F during all-day operation?

The steel housing and wheel absorb and radiate some of the 150 Degrees F inlet heat, raising discharge temperature slightly above the intake level.
