If the fan fails, or the duct gets damaged, or if a blockage reduces the duct airflow, the Chevron will tell you \u2013 unambiguously.<\/p>\n<p><strong>Easier to Afford.<\/strong>\u00a0Constantly measuring and remeasuring static pressure as the LEV is commissioned and balanced is an arduous and time-consuming task. Changes to the system, such as adding in new hoods, or increasing or balancing existing air velocities requires repeating the process, taking further precious time. Because the Chevron can be re-calibrated quickly and as often as you need, you save time and money.<\/p>\n<p>*<strong>\u00a0<em>\u2018Controlling airborne contaminants at work: A guide to\u00a0local exhaust ventilation\u2019<\/em><\/strong>\u00a0\u00a0\u00a0is an HSE publication \u2013 commonly know\u00a0as\u00a0<a href=\"https:\/\/www.hse.gov.uk\/pubns\/priced\/hsg258.pdf\" target=\"_blank\" rel=\"noopener\">HSG258<\/a>\u00a0\u2013 that sets out guidelines for designers and users of LEV.
