Vertical Laminar Air Flow Bench

CRESCENDO make Vertical Laminar Airflow Benches are designed to provide Class 100 workstations for creation of a bacterial dust free air space.

VLAFs are used for work with low risk substances and materials, when protection of working material from environment is necessary or the item requires a sterile working zone.

• SS 304 / CRCA powder coated construction except filters and motor-blower assemblies which will be in standard execution.
• Conventional Hepa Filter for supply which conforms to EU 12 Grade with an efficiency rating better than 99.97% for 0.3 µ. Also, Minipleat HEPA Filter with hot melt technology, which conforms to EU 13 Grade, with an efficiency rating better than 99.99% for 0.3 µ at supply position can be used.
• Primary pre filter for suction, which conforms to EU 6 Grade, with efficiency of 95% down to 5 micron. These Filters are basically made from micro-Fibre-glass washable media.
• Motor, Blower provided are statically and dynamically balanced to supply air flow with sufficient capacity and static pressure for entire life of HEPA. Blower is high performance, noise abated and light weighted.
• Magnehelic Differential Pressure Gauge (0 - 25 mm or 0-50 mm) to monitor pressure drop across HEPA Filter with respect to ambient.
• Fluorescent Light (250 Lux)
• ON/OFF Switches for motor & lights.
• 5/15 Amp single-phase switch socket for external equipment
• DOP Test port at upstream of HEPA filter
• Soft wall curtain to make Laminar Airflow direct on the work table

• Client to provide layout drawings (with respect to unit location) with dimensional details to enable us to work out exact dimensions of the Laminar Flow Unit. Also following details will be required to enable us to calculate length of ceiling suspension members & Polycarbonate / Equivalentside panels :
  Floor to Main Ceiling height
  Floor to False Ceiling height
  Floor to work table height
• Client to confirm the preferred location of the Control Panel and ON/OFF switch.
• In case of wall mounted or remotely located control panel, provision of any electrical cabling required from unit to control panel & control panel to the ON/OFF switch will be in Client scope.
• Client to confirm the location of supply pendant to enable us to decide on the entry of main cable in the unit to avoid any loose from projecting out.
• Concealing of electrical cabling (if required ) is in Client's scope.
• Client to provide facility of 20 psig compressed air / nitrogen cylinder any compressed gas not harmful to personnel for carrying out the HEPA Filter Integrity Test.

• HEPA Filter Integrity Test
• Particle Count Test
• Air Velocity Measurement Test
• Smoke Profile Test (Video Shooting/ Photography to be arranged by client )
