Specification before selection

Start with the duty.
Not just the diameter.

A fan is part of a system. The operating point and installation conditions help define the right configuration.

01 / PERFORMANCE

Airflow & pressure

Design volume flow, static or total pressure, operating range and duty cycle.

02 / ENVIRONMENT

Temperature & medium

Air temperature, dust, humidity, corrosion exposure and hazardous-area requirements.

03 / INTEGRATION

Installation & power

Available space, mounting direction, voltage, frequency and drive arrangement.

04 / VERIFICATION

Standards & records

Required approvals, inspection documents, test scope and project specifications.

Beyond the fan

Complete the
airflow system.

Coordinate the fan with the components around it. TWOSUN’s portfolio includes dampers, silencers, air terminals and control cabinets.
