Materials of Construction

• Main body: 1.2mm, 18 gauge steel with powder-coated finish
• Work table: 1.5mm, 16 gauge stainless steel, type 304
• Side walls: UV absorbing toughened glass (transparent)
• HEPA filters: For Vertical Down Flow (one) and Exhaust (two in series)
• H 14 as per EN 1822 – 99.997% @ 0.3 micron housed in a negative pressure envelope (shroud) to prevent escape of contaminated air to atmosphere and work area

Airflow Pattern

Unidirectional Vertical down flow with 70% re-circulated and 30% exhausted with makeup air coming in as inflow through table front perforations.

Average Air Flow Velocities with a uniformity of +/- 20%:

• Vertical down flow: 0.3 to 0.45 mps (60 to 90 fpm)
• Inflow: 0.45 mps (90 fpm)

Two independent hot-wire transmitters monitor real-time Down flow and Exhaust velocities.

Motor Blowers

• Single-phase 220-240 V 50 Hz AC induction motors with backward curve impellers separate for Vertical down flow and exhaust air.

Control Panel

• Microprocessor-based control panel is located at the front of the equipment, away from the contaminated airflow path.

Work Area Illumination

• >1200 Lux (>100 foot candles) using fluorescent tube lights located on the front panel away from the work zone.

UV Light

• Interlocked and programmed to work only when blowers and fluorescent lamps are off and the front window is fully closed.

Service Connections

• 2 gas/vacuum cocks are provided on one side panel with provision for 2 more on the other side panel.
• 2 ports each are available on side panels for signal cables.
• Two 5 A female electrical sockets with switches are provided on the unit’s back panel.

Mounting Stand, Front Sash, and Arm Rest

• Powder-coated square pipe mounting stand with castor wheels and locking arrangement is provided.
• Ergonomic design includes angled front sash with counterweights, magnetic switches for door positions, arm rest, eye-level LCD displays, alarms, etc., for operator comfort.

Testing and Certification

• Each unit is factory tested to meet international guidelines and dispatched in ready-to-plug and play condition with Operating Manual and IQ, OQ, PQ test certificates.
