Product Introduction

This 800 mm fan uses the largest selected rotor, tubular casing, motor and flanges in the hazardous axial group. Available temperature classes span T1-T4 depending on the complete build, and motor protection uses PTC sensors with compatible converter control. The large blade span supports central classified exhaust, but system inertia, structural loading and safe-speed limits require engineered starting and support arrangements.

Key Features

Central hazardous-air capacity

The large diameter serves exhaust mains that would require several smaller fans.

Temperature-class selection

Complete builds can be matched within the stated T1-T4 range to the actual ignition hazard.

Converter-ready protection

PTC monitoring protects the motor when used with the specified variable-speed control arrangement.

Technical Parameters

Primary Duty	High-volume classified exhaust main
Customization	Available based on the intended application and operating environment.

Applications

For high-volume hazardous clean manufacturing, chemical exhaust mains and large classified process ventilation systems.

Solutions for Your Application

Large rotating inertia causes excessive starting current or mechanical stress.Use the approved starter or converter ramp and coordinate motor protection with the wheel inertia.

Support movement reduces blade-tip clearance in the 800 mm casing.Provide rigid aligned supports, flexible duct connectors and vibration monitoring appropriate to the large assembly.

Available Options

Confirm zone, gas and temperature class, airflow, pressure, motor, converter, PTC interface, casing, guards, supports and monitoring.
