LEV Air Flow Indicators

The Need for Airflow Indicators.

Regulation 9 of COSHH 2002 (Maintenance, Examination and Testing of Control Measures) states that all LEV systems must be maintained in “efficient working order”. As an employer you therefore have a legal obligation to ensure that LEV systems keep working properly.

One simple way of achieving this is the use of airflow indicators at the extraction hoods to provide reassurance that the flow-rate is maintained and that the protection for employees is present at all times. The use of indicators is recommended within HSG 258 (Controlling Airborne Contaminants at Work), the latest guidance on LEV compliance from the HSE

About AES Airflow Indicators

The AES airflow indicator has been specifically designed for use in LEV systems. Constructed in stainless steel, the gauge displays the vacuum level at the adjacent duct or hood. All gauges are available with an adjustable ‘safe working zone’ visual indicator, which can be set to display the correct working range for the specific LEV hood. Gauges can be surfaced mounted or duct mounted.
