Produkteinführung

This small centrifugal exhaust unit packages a backward-inclined composite impeller inside a short square casing. Its documented 188-821 CFM range suits local cleanroom extract and return branches, and the inline arrangement can be oriented horizontally or vertically to follow available duct space.

Key Features

Restricted-space casing

The compact square body can replace a long scroll-fan assembly in a crowded ceiling or service chase.

No belt transmission

Direct drive removes belt tensioning and the associated maintenance access requirement.

Flexible duct orientation

The same inline form supports horizontal or vertical airflow when installed within its mounting limits.

Technische Parameter

Applications

Small cleanroom exhaust branches, gowning-room return air, laboratory support extract and equipment-cabinet ventilation.

Solutions for Your Application

There is insufficient ceiling length for a housed centrifugal fan and transitions.Install the short square inline unit directly between rectangular duct sections.

A belt drive would add particulate-producing wear components above a controlled zone.Use the direct-drive wheel and maintain access to the motor and impeller through the service panel.

Verfügbare Optionen

Speed controller, disconnect, motorized isolation damper, coated casing, flexible connectors and vibration isolation can be supplied.
