The Series-M molecular filtration fume hoods represent the ideal solution for protecting personnel exposed to the inhalation risks associated with harmful volatile chemical substances generated during handling operations. Thanks to their integrated filtration system, they provide personnel protection without the construction and energy costs associated with complex ventilation systems required to duct air outside the building.

The distinctive reverse-flow architecture, with the filtration system located beneath the work surface, allows for generous internal working heights (up to 120 cm) while maintaining an extremely compact overall external height of only 220 cm.

It can equip one or more activated carbon filters for vapors retention or absolute filters for particles (HEPA H14 or ULPA U17). Combination of different types of filters can be equipped as well,  in order to enanche the retention capability in accordance to user’s needs. In compliance with BS and EN Standards and international health & safety regulations.

It features:

• High containment factor ensured by an especially designed aerodynamic
• High efficient activated carbon filtration system, BS7989:2001 certified with specific tests against isopropyl alcool, ammonia, sulphur dioxide and formaldehyde showing a 99% filtration efficiency
• Absolute particles filter availability HEPA classe H14 (99.995% @ 0,3 µm-Rif. EN1822:2009)
• Pre-filtration through dust-prefilter M6 class to prevent premature saturation of the main filters
• Counterweighted sliding front and lateral panels made with laminated safety glass (3+3 PVB) that ensure high chemical resistance and durability
• Variable speed embedded fan according to frontal sash position (VAV system – variable air volume)
• Internal IP65 lighting wiith 1000lux capability
• Three sizes availability: 1200/1500/1800 mm widths

CE marking

• 2006/42/UE Machinery Directive
• 2014/35/UE Low Voltage Directive (50-1000 V)
• 2014/30/UE Electromagnetic Compatibility Directive
• 2011/65/UE ROHS Directive

The M-Series hoods are quipped with a continuous fan-speed change triggered by sliding sash movement (VAV: variable air volume), electronic control system TIMELOG that through a touch screen display allows the reading and setting of fume cupboard functions.

The control panel of the fume cupboard (TIMELOG) allow a real-time showing of  main functional parameters such as:

• air face velocity and exhausting flow rate
• residual time to next filter or prefilter replacement/control (two different timers)
• working opening height
• air temperature
• warming-up cycle with self-testing routint of the prefilter saturation level

The TIMELOG allow the showing of the following alarms:

• air face velocity below the safety-threshold
• working opening height above maximum
• air-temperature beyond maximum level for a good absorption capacity
• expired filter/prefilter estimated lifetime

STANDARDS

The whole range of filtration fume cupboard GS-Series has been designed, manufactured and certified following the prescriptions of the best international standards:

• BS7258:1994 – Laboratory fume cupboards: specification for safety and performance
  Containment and face air-velocity test
• BS7989:2001 – Specification for recirculatory filtration fume cupboards
  Retention capacity and efficiency test of the activated carbon filtration system installed on a recirculating fume cupboard. The reference chemicals used within this standard are: isopropyl alcohol, ammonia, formaldehyde and sulfur dioxide
• ANSI/ASHRAE110:1995 – Method of Testing Performance of Laboratory Fume Hoods
  Containment and face air-velocity test
