The GS-Series filtration fume cupboards represent the most comprehensive and advanced range of safety cabinets to protect laboratory personnel and the environment from toxic chemicals released during handling of harmful chemicals within laboratory applications. Thanks to the its own embedded filtration system allows the protection of personnel without the need of any complex ventilation system and energy wasting for air renewal. The units can be ducted also using a wide range of available accessories such remote-blower, thimble, manifolds connections keeping at the same time the filtration system on board.

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, tested to EN14175-3 and EN14175-6 at 0.3m7s and 0.5m/s face velocity from authorized body
• 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
• Air-tight plenum that guarantees zero leakages
• 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
• Four sizes availability: 1000/1200/1500/1800 mm widths

Functional flexibility

The whole GS-Series fume cupboard range can work within three different modes:

• R-MODE: 100% recycle mode. The fume cupboard is equipped with filtration system and fan and recycle lab-air without affectin the ventilation system of the lab
• FE S/M-MODE: filtration+exhaust mode with embedded fan. The fume cupboard is equipped with filtration system and fan and works exhausting the air thorugh a duct collard in a exhausting-pipe using on-board fan but keeping at the same time the filtration system on board. This solution simplifies the installazion of the unit as no remote-fan is required.
• FE-C/M-TH-MODE: filtration+exhaust mode with embedded fan and THIMBLE connection to the ventilation system. The fume cupboard is equipped with embedded filters and fan; the filtered air is conveyed outside through a thimble connection linked to an existing ventilation duct equipped with an auxiliary remote blower as well. This solution allow to decouple the containment of the hood from the design point of the ventilation system.
• FE C/M-MODE: filtration+exhaust mode with remote fan. The fume cupboard is equipped with filtration system and works exhausting the air thorugh a duct collard in a exhausting-pipe using a frequency-conveter-controlled fan but keeping at the same time the filtration system on board. This solution allow to fit installation-sites where long-exhausting pipes are present and where total negative pressure is strictly required from the working area within the unit up to the external. According to exhaust-system layout the fume cupboard can even be equipepd with a parzialization valve.

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 GS-Series is available in two versions:

• STANDARD: equipped 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.
• BASE: equipped with automatic variation on three steps of pre-settable speed of embedded fan in accordance with the opening of the sliding glass, visual low air-flow alarm (risk of loss of containment) and device hour counter for the management of the maintenance scheduled actions.

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
• DIN 12924

Furthermore, the whole range of GS-Series is manufactured according to EN14175-2 requirement, and it is provided with conformity declaration certificate.

All models have been tested and certified to EN14175-3 and EN14175-6 both at 0.3 and 0.5m/s face velocity.
