Overview
The document describes the ATM Measuring and Control Unit, a system designed for accurate air flow measurement and control in ventilation systems. It highlights the unit's patented technology, ease of installation, and unique features that ensure optimal ventilation.

Specifications
The ATM unit is a chimney module equipped with an airflow transmitter and a control valve. It is designed to be mounted below a Fancom fan unit or between sections and a central duct in a central exhaust system. The unit is available in diameters ranging from 35 to 80 cm.

Accurate Ventilation
The system guarantees precise ventilation by continuously measuring and adjusting airflow, which helps maintain optimal living conditions for animals. This precision reduces energy consumption and heating costs by preventing excessive ventilation and heat loss.

Simple Mounting
The ATM unit features a robust chimney design with an ingenious click system for easy installation and removal, facilitating cleaning and maintenance.

Unique Features
- Minimum tip wobble of the airflow transmitter ensures comprehensive measurement of the chimney surface.
- The patented shape of the airflow transmitter ensures RPM is proportional to air volume, crucial for accurate measurement in minimum ventilation zones.
- Direction-sensitive RPM feedback prevents wind interference in measurements.
- The contra-rotating control valve promotes unimpeded airflow.

Properties of Patented Fancom Airflow Transmitter
The system is designed to remove excess heat and unwanted gases like CO2, with ventilation levels adjusted according to the age of the animals. The Fancom ATM unit ensures continuous and precise measurement and control of ventilation levels.
