Product description

The Nederman LEV Monitor airflow indicator has been designed to provide continuous monitoring, at regular intervals, of individual extraction points in a Local Extract Ventilation (LEV) system. At a glance, personnel working in hazardous industries can be reassured that their extract system is working correctly and that their safety has not been compromised by malfunction or blockage. The LEV Monitor is simple to fit, simple to set up and simple to use.

The LEV Monitor has been specifically designed to address the monitoring requirements of Local Extract Ventilation (LEV) systems. It allows operators to comply with the requirements of HSG258 and the COSSH regulations. Nederman LEV Monitors can be an integral part of fume cupboards and biological safety cabinets manufactured not only by Nederman but by any brand of LEV equipment.

Principle of operation:
The LEV Monitor operates by monitoring the static pressure in the extract duct. The sample tube from the unit is fitted to the duct, close to the point of extract, using an extended grommet or tapped hosetail. Firstly, the extract system (LEV) is set up to ensure a safe working environment, using dampers, fan speed controllers and bypasses. This process is continued until every extract point in the system is working safely and within the guidelines for the material being extracted.

The calibration mode is then selected on the LEV Monitor airflow indicator, using a simple magnetic actuator. This ‘normalises’ the LEV Monitor to the conditions now observed, and continuous periodic monitoring commences. The Nederman LEV Monitor measures negative pressures in the range of -100 to –2000 Pascals.

The duct pressure is sampled every 15 seconds, and the display updated accordingly. Whilst the static pressure in the duct stays adequate for safe air removal, the LEV Monitor shows this, continuously moving, display. If the negative static pressure within the duct drops by more than 20%, the LEV Monitor recognises this as an unsafe condition. This triggers a series of flashes of the LED below the display, after which the display changes to the graphic shown, flashing on and off approximately twice per second. Thereafter, the red LED below the display flashes approximately every 5 seconds.
