Produkteinführung

The 1455 CFM model is a defined medium-duty inline fan rather than a scaled label change. Its 17 x 17 x 21 inch casing contains an 11 inch aluminum impeller driven by a 1/4 hp motor, giving it a distinct size and service range for general cleanroom exhaust or return air.

Key Features

Defined medium hardware

The documented wheel, motor and enclosure dimensions simplify replacement and duct-layout coordination.

Aluminum rotating assembly

The 11 inch impeller combines low rotating mass with corrosion resistance for general air service.

Inline service access

The square enclosure keeps the motor and wheel accessible without adding an external scroll casing.

Applications

Medium cleanroom return systems, general exhaust headers, makeup-air transfer and non-corrosive process support ventilation.

Solutions for Your Application

An undersized local fan cannot overcome the medium branch resistance at peak airflow.Select the operating point within the 831-1455 CFM range and verify available pressure against the duct calculation.

Maintenance staff need known dimensions for a planned fan replacement.Use the 17 x 17 x 21 inch envelope and 11 inch wheel specification to coordinate the opening and service clearance.

Verfügbare Optionen

Motor voltage, speed control, factory disconnect, backdraft damper, isolators and corrosion-resistant finish can be selected.
