HSG258 Guidance now requires ‘Airflow indicators’ to be installed on LEV systems. Our new range of analogue manometers with a vacuum range between 750 and 2500 Pascals are ideal for this task.
Section 106 states: “ Employers need to ensure that LEV systems continue to work properly. There are several ways of checking this, such as using an anemometer, dust lamp or smoke tracer – with the work process running. But the simplest way is probably to use an airflow indicator. This will give the operator a simple indication that the hood/LEV is working properly. It becomes critical when the operator has to adjust a damper to get adequate airflow. The airflow indicator must indicate simply and clearly when the airflow is adequate. The simplest indicator is usually a manometer “
