Centrifugal Roof Exhaust Fan 1049 CFM

A compact direct-drive upblast fan for small general exhaust systems discharging vertically above the roof.

199-1049 CFM range
1/8 hp direct drive
19 x 19 in curb cap

Introduction de produit

This small centrifugal roof fan covers 199-1049 CFM with a 1/8 hp direct-drive motor and 19 x 19 in curb cap. Its compact aluminum wheel and upblast discharge suit small cleanroom general exhaust where discharge should be directed away from the roof surface. The model is intended for ordinary ventilation air; grease, corrosive or hazardous exhaust requires construction selected for that specific duty.

Key Features

Compact roof footprint

The 19 in-square cap fits a small curb and low-volume exhaust riser.

Vertical upblast discharge

Air leaves above the roof rather than washing directly across the roof membrane.

Simple direct drive

The motor couples directly to the wheel without belts requiring periodic tensioning.

Solutions for Your Application

The actual duct static reduces flow below the required room exhaust rate.Select the fan at the calculated system pressure rather than using the 1049 CFM free-air endpoint.

Roof leakage develops around an incorrectly sized curb or flashing.Match curb cap, curb height and roofing details before installation and preserve service access.

Options disponibles

Confirm airflow and static, voltage, speed control, curb, backdraft damper, disconnect, coating, birdscreen and roof weather details.
