Air Supply Anemostat SpiroFlex AN100 (ANEMOSTAT NAWIEWNY 100) — round ceiling diffuser, Ø100 mm

SpiroFlex AN100 air supply anemostat is a round ceiling diffuser with a nominal diameter of 100 mm designed for supply air distribution in ventilation and HVAC systems. The AN100 delivers controlled directional airflow for rooms where localized air distribution or balancing is required. Constructed for installation in duct outlets or suspended ceilings, this diffuser is compatible with residential and commercial ventilation setups and provides a compact option for finishing supply air terminals.

Advantages

The round design and fixed outlet geometry ensure even distribution of supply air while maintaining a low profile in ceilings. The AN100 is simple to install and integrates into standard ductwork and suspended ceiling tiles. Its compact dimensions make it suitable for installations with limited ceiling space and enable precise directional airflow control for improved indoor comfort and system balancing.

Suitable for

• Supply air outlets in residential ventilation systems
• Localized supply in offices and small commercial rooms
• HVAC balancing and room air distribution adjustments
• Installation in suspended ceilings or directly on ducts

Key specifications

• Nominal diameter: 100 mm (round)
• Application: supply air diffuser for ceiling or duct outlet
• Air distribution: directional supply with controlled plume
• Installation: suitable for suspended ceilings and duct-mounted outlets
• Typical uses: residential and light commercial ventilation

How to use

Mount the AN100 diffuser at the supply air outlet in the duct or into the suspended ceiling tile opening sized for the nominal diameter. Ensure the diffuser is securely fastened and sealed to avoid leaks at the connection to the ductwork. Adjust the orientation to direct airflow toward the intended zone; final balancing and airflow adjustment should be performed via the system’s dampers or balancing valves according to design airflow rates.

Usage recommendations

For optimal performance, use the AN100 as part of a balanced ventilation system and verify airflow with anemometers during commissioning. Keep the diffuser clean and free of obstructions; periodic inspection and gentle cleaning will maintain airflow characteristics. When integrating into suspended ceilings, confirm cut-out dimensions and support to avoid vibration or air leaks.
